Show answer & explanation

Explanation

The correct answer is Option 4 i.e 60

Understanding

Application

Let initial income of B = 100

Then, 

Initial Income of A = 150

Total initial income = 100 + 150 = 250

Income of A is increased by 40%:

New income of A = 150 × 1.4 = 210

Income of B is increased by 90%:

New income of B = 100 × 1.9 = 190

Total new income = 210 + 190 = 400

Hence,

Percentage increase = [(400 – 250)/250] × 100 = 1500/25 = 60%
