Question 55

A is 20% more than B, which is 25% less than C. Which of the following is true about A and C?

Solution

Consider C=100

Given B=25% less than C = 100 - (100 $$\times $$ 25%)

= 100 - (100 $$\times $$ 0.25)

= 100 - 25

= 75

A=20% more than B

= $$75+(0.2\times75)$$

= 90

To find C is how much percent less than A, we have C = 100 and A = 90 , B= 75

$$\frac{A}{C}$$ =$$\frac{90}{100}$$

$$\frac{A}{C}$$=0.9
