The monthly salaries of P and Q are in the ratio 4 : 3. If P and Q get an increase of 10% and 5% of their existing salaries respectively, what will be the new ratio?

  1. 88 : 63

  2. 63 : 88

  3. 45 : 60

  4. 60 : 45

Show answer & explanation

Answer: (A) 88 : 63

Explanation

Take the salaries as 4x and 3x. After the raises: 4x × 1.10 = 4.4x and 3x × 1.05 = 3.15x. The ratio is 4.4 : 3.15 = 440 : 315 = 88 : 63.
