134. The price of the wheat is increased by 20%, so Shon has decreased its consumption by 20%. What is the percentage of the expenditure of wheat decreased by Shon?

गेहूं की कीमत में 20% की वृद्धि होने पर, शॉन ने इसकी खपत में 20% की कमी की। शॉन द्वारा घटाए गए गेहूं के व्यय का प्रतिशत क्या है?

Option “D” is correct.

Let the initial price of the wheat=Rs.x

Consumption of the wheat=y kg

Expenditure=x * y=xy

After increasing the price=x * 120/100=1.2x

After decreasing consumption of the wheat=y * 80/100=0.8y

Required percentage= [(xy – 1.2x * 0.8y)/xy]* 100

=(0.04/1) * 100

Option “A” is correct.

Let total marks be x.

Then, 225 = (48/100) * x + 9

x=450

Required Difference=225 – 180=45

136. A’s salary is 120% of B’s salary and B spends 60% of his salary for house rent and education fees. If B’s savings is Rs.1800 and A’s expenditure is 40% more than that of B, then what is the saving amount of A?

A का वेतन B के वेतन का 120% है और B अपने वेतन का 60% घर के किराए और शिक्षा शुल्क में खर्च करता है। यदि B की बचत 1800 रुपये है और A का व्यय B की तुलना में 40% अधिक है, तो A की बचत राशि क्या है?

Option “B” is correct.

B’s savings = 1800

B’s expenditure = 60/40 * 1800 = 2700

B’s income = 2700 + 1800 = 4500

A’s income = 120/100 * 4500 = 5400

A’s expenditure = 2700 * 140/100 = 3780

A’s savings = 5400 – 3780 = 1620

137. The sum of (3/5)th a number and 42 % of the same number is 255. What is the 54 % of the number?

किसी संख्या का (3/5) और उसी संख्या का 42% का योग 255 है। संख्या का 54% कितना है?

Option “D” is correct.

 (3/5)x + (42/100)x = 255

(60x + 42x)/ 100 = 255

(102x/100) = 255

x= 255*(100/102) = 250

54 % of the number = 250*(54/100) = 135

138. A saves 40% of his income and B saves 20% more than A. If the income of A is 80% of the income of B and A’s expenditure is Rs.18000, then what is the expenditure of B?

Option “B” is correct.

A’s income=80/100 * B=4B/5

A’s income=100/60 * 18000=30000

A’s saving=30000 * 40/100=12000

B’s savings=12000 * 120/100=14400

B’s income=5/4 * 30000=37500

Expenditure of B=37500 – 14400=23100

139. 18% of the total number of TOI newspaper readers is equals to 8% of the total number of The Hindu newspaper readers. If 7560 people read The Hindu newspaper, then how many of people read TOI newspaper?

TOI अखबार के पाठकों की कुल संख्या का 18%, द हिंदू अखबार के पाठकों की कुल संख्या के 8% के बराबर है। अगर 7560 लोग द हिंदू अखबार पढ़ते हैं, तो कितने लोग TOI अखबार पढ़ते हैं?

Option “B” is correct.

18% of the total number of TOI readers = 8% of the total number of The Hindu readers

TOI readers/The Hindu readers = 8/18 = 4/9

Let TOI readers = 4a then The Hindu readers = 9a

According to the question, 9a = 7560

a = 840

The number of TOI readers = 4a = 840*4 = 3360
