Question 68

A is 25% less than B. B is 30% more than 120. What is the value of A?

Solution

B is 30% more than 120.

B = 120 of (100+30)%

= 120 of 130%

= $$120\times\frac{130}{100}$$

= 156

A is 25% less than B.

Value of A = 156 of (100-25)%

= 156 of 75%

= $$156\times\frac{75}{100}$$

= $$156\times\frac{3}{4}$$

= 117
