Question : A is 25% less than B and B is 30% more than 120. What is the value of A?
Option 1: 117
Option 2: 111
Option 3: 114
Option 4: 108
Correct Answer: 117
Solution :
A is 25% less than B.
B is 30% more than 120.
Value of B = 120 + 30% of 120
$= 120 + \frac{30}{100} \times 120 = 120 + 36 = 156$
Value of A = B – 25% of B
$= 156 - \frac{25}{100} \times 156 = 156 - 39 = 117$
$\therefore$ The required value of A is 117.
Hence, the correct answer is 117.
