Set-75
Study the following graphs and answer the given questions.
Total investment of Virat and Krish in six schemes (in lakhs)


1. What is the respective ratio between total amounts invested by Virat in schemes B and E together and total amount invested by Krish in the same schemes together? 

Ans:3
Total amount invested by Virat in schemes B and E together= 56% of 6000000+ 40% of 7200000 = Rs 6240000
Similarly, Total amount invested by Krish in schemes B and E together= 44% of 6000000+ 60% of 7200000 = Rs 6960000
Required ratio= 6240000:6960000
= 26:29

2. Scheme A offers simple interest at a certain rate of interest. If the difference between the interests earned by Virat and Krish from scheme A after 5 year is Rs 638400, then what is the rate of interest per annum?

Ans:1
Amount invested by Virat in scheme A= 64% of 7600000
= Rs 4864000
Amount invested by Krish in scheme A=7600000-4864000
= Rs 2736000
Let the rate of interest be r% per annum.
Then [(4864000*r* 5)/100]-[(2736000*r*5)/100] = 638400
2128000*r*5= 63840000
r=6%

3. Amount invested by Virat in scheme H is equal to the amount invested by him in scheme A.  The rate of interest per annum of schemes A and H are same.  The only difference is scheme H offers compound interest, whereas the scheme A offers simple interest. If the difference between the interests earned by Virat from both the scheme after 2 year is Rs 70041, then what is the rate of interest? (Approximately)

Ans:3
Amount invested by Virat in schemes A and H=64% of 7600000
= Rs 4864000
Let the rate of interest be r% per annum.
Then,
70041= (4864000*r*r)/1002
r2 = 144
r= 12%

4. If scheme E offers compound interest at 16% per annum, then what is the difference between interest earned by Virat and Krish from scheme E after 3 years?

Ans:1
Difference between the amount invested by Virat and Krish in scheme E=20% of 7200000 = Rs 1440000
Then Difference of interest earned by both of them= 1440000[((1+ (16/100)3) -1]
= 1440000(1.5608-1) = 1440000(0.5608) = Rs 807690

5. If Krish invested in Scheme F for 4 years. If scheme F offers simple interest at 9% per annum for the first two years and then the sum with interest is invested for compound interest at 15% per annum for the third and fourth year, then what will be the interest earned by Krish after 4 year?

Ans:5
Amount invested by Krish in scheme F=40% of 10000000
=Rs 4000000
Then total interest earned by Krish after 4 year= (4000000*2*9/100) + 32.25% of 4720000
= 720000+1522200
= Rs 2242200

Set-76
Study the following and answer the following questions.
The following line graph gives the annual percent profit earned by a Company during the period 2010-2015. Read the graph carefully and answer the following questions.
Percent profit earned by Two Companies during 2010-2015

Note: Profit percent= [(Income-Expenditure)/Expenditure]*100
6. If the expenditure of Company A in 2013 is 25% more than the expenditure of Company B in 2015, then the income of Company B in 2015 is what percent less than the income of Company A in 2013?

Ans:3
Let us take the expenditure of company B in 2015 is Rs.100
Expenditure of company A in 2013 is Rs.125
Income of company B in 2015 = 100 * 150/100 = Rs.150
Income of company A in 2013 = 125*160/100 = Rs.200
Required percentage = (200-150)/200*100
=> 50/200*100 = 25%

7. If in the year 2010, the profit made by company A was Rs 60 crores, then what was its income in that year?

Ans:2
Let the expenditure of Company A in 2010 be Rs 100x crores.
Since the profit percentage is 50 %, the income of Company A in 2010 be Rs 150x.
Since, the profit made by company A was Rs 60 crores we can say that
50% of 100x= 60
(i.e) 50x=60
X = 6/5
Then the income of Company A=150*6/5= Rs 180 crores

8. If in the year 2012, the expenditure of both companies A and B were equal, then what is the ratio of their respective incomes of Company A and B in the same year?

Ans:1
Let the expenditure of Company A and expenditure of Company B in 2012 be Rs x.
Also let income of Company A be Rs P and income of Company B be Rs Q.
Now, In 2012 for Company A,
45= [(P-x)/x]*100
45/100= (P/x)-1
145/100=P/x
P=145x/100
Similarly, For Company B,
35= [(Q-x)/x]*100
35/100= (Q/x)-1
135/100=Q/x
Q=135x/100
Required ratio= (145x/100)/ (135x/100) = 29:27.

9. If company A and company B has equal profit in 2013, then income earned by company B is approximately what percent of the expenditures incurred by company A?

Ans:3
Let the expenditure of company A be Rs 100x and the expenditure of company B be Rs 100y.
Then the income of company A and company B be Rs 160x and Rs 135y.
Since, company A and company B has equal profit in 2013,
60% of 100x=35% of 100y
(i.e) 60x=35y
x/y=7/12
Then, required percentage = (135y/100x)*100
= 135*12/7
= 230% (Approximately)

10. During which year the ratio of percentage profit earned to that in previous year by the company A is maximum?

Ans:1
In 2011=30/50=0.6
In 2012=45/30=1.5
In 2013= 60/45=1.33
In 2014=55/60=0.91
In 2015= 40/55=0.72
Thus, In 2012 the ratio of percentage profit is Maximum.
