When the price of an item decreased by 20%, the number of items sold increased by 30%. What was the percentage increase on the total revenue?

A)
20%

B)
6%

C)
5%

D)
4%


Correct Answer :

4%


Explanation :

Let cost of each item = Rs.100 & sale = 100 item .
Revenue = Rs.(100*100) = Rs.10000

New cost per item= Rs.80 and New sale = 130 item
New Revenue = Rs.(80*130) = 10400

Percent Change =(new - old)/(old)= (400/10000)*100 = 4%

D)
1054


Correct Answer :

1054


Explanation :

The difference in percentage = 78% - 59% = 19%

If 10% of x = 20% of y, then x:y is equal to?

A)
1:2

B)
2:1

C)
5:1

D)
10:1


Correct Answer :

2:1


Explanation :

10% of x = 20% of y

x/10 = y/5
x/y = 10/5 = 2/1
x:y = 2:1

If Aditya’s salary is 25% more than Amit’s salary, then Amit’s salary is how much less than Aditya’s salary?

A)
16.67%

B)
32.5%

C)
20%

D)
22.5%


Correct Answer :

20%


Explanation :

Let Amit’s Salary is Rs. 100. Then,
Aditya’s Salary = (100 + 25% of 100) = Rs. 125.
Difference between Aditya’s Salary and Amit’s Salary = 125 - 100 = Rs. 25.
% Difference (lower) = (25/125)*100 = 20%

Amit’s salary is 20% lower than Aditya’s.

If the numerator of a fraction is increased by 150% and the denominator is increased by 300%,then the resultant fraction is 5/12 . What was the original fraction?

A)
2/3

B)
1/3

C)
3/5

D)
3/5


Correct Answer :

2/3


Explanation :

Let the original fraction =x/y

New fraction =(250x/100)/(400y/100)=5/12
250x/400y =5/12
5x/8y=5/12
x/y =8/12 =>2/3

The boys and girls in a college are in the ratio of 3 : 2. If 25% of the boys and 20% girls are adults, percentage of students who are minor is?

A)
75%

B)
77%

C)
80%

D)
90%


Correct Answer :

77%


Explanation :

Suppose boys = 3x and girls = 2x
Number of minors= (75% of 3x) + (80% of 2x)
=(75*3x/100)+(80*2x/100)
= 9x/4 + 8x/5 =77x/20

Required percentage =(77x/20)*(1/5x)*100 => 77%

The price of a car is Rs. 4,50,000. It was insured against accident to 90% of its price. When the car was damaged completely in an accident, the insurance company paid 95% of the insurance. What was the difference between the price of the car, and the amount received?

B)
Rs. 65,500

C)
Rs. 65,250

D)
Rs. 66,000


Correct Answer :

Rs. 65,250

so amount paid by insurance company=450000*90/100 * 95/100=45*90*95 =384750
the difference between the price of the car and the amount received

=450000 − 384750
=65250
