1. The average weight of 13 boys in a class is 57 kg and if a boy walks out of the class the average is decreased by 3/4 kg. What is the weight of the boy who walked out of the class?

Ans: 2
Let the weight of the boy, who walked out of the class be ‘x’.
So, x = 13*57 – 12*(57-3/4)
The weight of the boy = 13 * 57 – 12 * (57 – 3/4) = 66.

 

2. Ratio of girls to boys in a class in 2016 was 20 : 9 and the ratio of girls to boys in the same class in 2017 is 11 : 9. Find the total number of boys in the class in 2016 if the ratio of total number of students in the class in 2016 to the total number of students in the class in 2017 is 29 : 40 and total number of girls in the class in both the years is 84.

Ans: 4
Let number of girls and boys in 2016 = 20x and 9x respectively.
Let number of girls and boys in 2017 = 11y and 9y respectively.
According to question-
=> (20x + 9x) : (11y + 9y) = 29 : 40
=> 29x : 20y = 29 : 40
=> y = 2x
And,
=> 20x + 11y = 84
=> 20x + 22x = 84
=> x = 2 and y = 4
Total number of boys in the class in 2016 = 9x = 9 * 2 = 18

 

3. A, B and C entered into a partnership such that the initial investment of A is half of C and initial investment of B is 25% less than that of C. A, B and C withdrew Rs.2000, Rs.5000 and Rs.8000 respectively after 4 months, 5 months and 3 months respectively such that at the end of 6 months profit is divided in 56: 85: 96 ratio. Find the sum of initial investment of A, B and C.

Ans: 2
Let initial investment be,
C = 2t
A = t
B = 1.5t
Ratio of profit share after 6 months is,
=> {t*4 + (t – 2000)*2} : {1.5t*5 + (1.5t – 5000)*1} : {2t*3 + (2t – 8000)*3}
=> (6t – 4000) : (9t – 5000) : (12t + 24000)
Now, ratio given = 56: 85: 96
(6t – 4000) /(9t – 5000) = 56/85
85*6t – 56*9t = 85*4000 – 56*5000
6t = 60000
We get,
t = 10000
So,
Investment are,
A = 10000, B = 1.5t = 15000 and C = 2t = 20000
Sum = 10000+15000 + 20000 = Rs.45000

 

4. To promote his movie SRK announces 20% instant cash back on LayTm app booking which otherwise had costed Rs.250. Due to this the sales of the movie tickets increased by 28%. Find the increase in percentage of number of people who have watched the movie.

Ans: 2
=> Let the initial number of people =100
=> Total revenue =100*250= 25000
=> New cost after cash back =80/100*250
=> =200
Since, sales increased by 28%.
=> Thus, now, total revenue =128*25000/100=32000
=> New no. of people who have cash back= 32000/200
=> =160
=> % increase = ((160-100)/100)*100
=> 60%

 

5. A’s salary is 25% lower than B’s salary, which is 20% lower than C’s salary. D’s salary is 14.28% more than C’s salary. By how much percent (approx.) D’s salary is more than A’s salary?

Ans: 3
Let B’s salary be Rs. 100. Then,
A’s salary = (100% – 75%) 100 = Rs. 75
C’s salary = 100/((100%-20%))= Rs. 125
D’s salary = (100% + 14.28%) 125 = 8 * 125 / 7 = Rs. 142.85
Required % = (142.85 – 75)/75 = 90.47%

 

6. A whole seller mixes three variety of rice costing Rs.40/kg, Rs.48 per kg and Rs.55/kg in the quantity 3 kg, 5 kg and 8 kg respectively. He sells this mixture to a shopkeeper at a profit of 5% and the shopkeeper sells the same mixture to his customer at a profit of 10%. Find the amount paid by customer if he purchases 12 kg rice.

Ans: 4
Total quantity of rice mixed = 3 + 5 + 8 = 16 kg
Total cost of mixer = (40 * 3) + (48 * 5) + (55 * 8) = 120 + 240 + 440 = Rs.800
Per kg cost of mixer for whole seller = 800/16 = Rs.50
Per kg cost of mixer for shopkeeper when whole seller made 5% profit = 105% of 50 = Rs.52.5
Per kg cost of mixer for customer when shopkeeper made 10% profit = 110% of 52.5 = Rs.57.75
Total amount paid by customer for 12 kg of this mixture of rice = 57.75 * 12 = Rs.693

 

7. A sum of money becomes two times in 8 years at simple interest and it becomes four times in 2 years at compound interest. Find the ratio of rate of simple interest to rate of compound interest –

Ans: 2
Let principal is P and rate is r1 for simple interest and r2 for compound interest.First Case:-

P = (P * r1 * 8)/100

r1 = 12.5%

Second Case:-

4P = P(1 + r2/100)2

r2 = 100%

Ratio = r1:r2 = 12.5:100 = 1:8

 

8. Average age of 8 persons of a team is 22.5 years, out which A is 4 years older to B. 2 years ago the average age of team excluding the age of A and B is 20 years. Find the ratio of ages of A and B respectively after 6 years from present.

Ans: 4
Let the present age of B = P years and present age of A = (P + 4) years.
Total age of 8 persons at present = 22.5 * 8 = 180
Average age of 6 persons before 2 years = 20 years. So, average of those 6 persons at present = 20 + 2 = 22 years.
Total age of 6 persons at present = 22 * 6 = 132
Sum of ages of A and B = P + P + 4 = 180 – 132 = 48
=> 2P = 44
=> P = 22
Age of A after 6 years = P + 4 + 6 = 22 + 10 = 32 years
Age of B after 6 years = P + 6 = 22 + 6 = 28 years
Required ratio = 32: 28 = 8: 7

 

9. Harish going in his car from city X to city Y takes eight hours travelling at a speed of 75 kmph, while Mahesh travels the same distance in ten hours. If Harish travelled the distance at a speed of 5 kmph more and Mahesh at 10 kmph less then what would be the difference between the time taken by Mahesh and Harish to cover the distance?

Ans: 1
The distance between cities X and Y = 75 x 8 = 600km.
Speed of Mahesh = 600/10 = 60 kmph
Therefore, the difference between the times taken by Mahesh and
Harish = (600/(60 – 10)) – (600/(75 + 5)) = 4.5 hrs.
Hence the correct option is (1).

 

10. A is twice as good as workman as B and together they finish a piece of work in 16 days. In how many days will A alone finish the work ?

Ans: 2
(A’s 1 day’s work) : (B’s 1 day’s work) = 2 : 1
(A + B)’s 1 day’s work = 1/16
Divide 1/16 in the ratio 2 : 1
Therefore, A’s 1 day’s work = (1/16 * 2/3)
= 1/24
= 24 days
Hence, A alone can finish the work in 24 days

This time, he joined Beer Biceps YouTube page for an interview to discuss many aspects of bodybuilding, together with his first steroid cycle.
    As bodybuilding evolves, the controversy on steroid ethics continues, challenging newcomers to make aware selections. Ronnie Coleman once mentioned he used up to 7,000 milligrams of steroids a week6. He various his steroid types, using testosterone, Trenbolone, and Winstrol. Sooner or later, anabolic steroids do begin to showcase their damaging impact on the physique.
    He reflects on the importance of heavy lifting and muscle density in bodybuilding, noting these were key to his distinct physique and success. As a matter of fact, I’d by no means be confused with how Coleman would have turned out with similar work ethic and dedication and no medication in any way. Ronnie Coleman opened up a couple of run-in with the DEA and the consequences of his again surgical procedures. Ronnie Coleman is amongst the finest bodybuilders to ever step on the Olympia stage.

Ron Coleman was a choose at (drug-tested) MuscleMania contests and wrote for All-Natural Muscular Development journal for years.
    By following the recommended dosage and steering, users can confidently enjoy the optimistic outcomes of the product with out undue concern about these manageable side effects. Regardless Of his legendary standing, Mr. Coleman remains remarkably humble. He shares experiences from his time as a police officer, witnessing life’s harsh realities.
    Eight Mr. Olympia titles from 1998 to 2005, an era characterised by unparalleled dominance, solidified Ronnie Coleman’s standing as one of many greatest bodybuilders of all time. He added that for the final 5 or 6 years of his career, he procured steroids legally, which usually required blood exams, prescriptions, and specific pharmacies. It’s essential to notice that the specifics of Ronnie Coleman’s steroid cycle are based mostly on real interviews and details. In Ronnie Coleman’s case, the controversy surrounding steroid use is notable due to his standing as one of the sport’s greatest champions. While he never failed a drug take a look at during his aggressive profession, there was widespread hypothesis and discussion about the extent of his steroid use. First, let’s clarify that there are actually two former pro bodybuilders named Ronald Coleman, and so they both started on the identical path.
    It is essential to make use of proper form and technique when lifting weights and to include different forms of exercise and bodily activity into your routine.
