Explanation

Let A = 3x, B = 5x

Increase B by 20% → new B = 5x × 1.2 = 6x

New ratio = A : B = 3x : 6x = 3 : 6 = 1 : 2

Green ratio = 5 parts = 60

1 part = 60 ÷ 5 = 12

Total ratio = 3 + 4 + 5 = 12 parts

Total value = 12 × 12 = 144

Explanation

Profit is divided in the ratio of (capital × time).

Given:

• Capital ratio A : B = 4 : 5
• Time: A = 9 months, B = 9 months

So time is same, only capital matters:

Profit ratio = 4 : 5

Total profit = 22000

Total parts = 4 + 5 = 9

A’s share:

4/9​×22000=9777.78≈9778
