Given:
A invested = Rs. 63000 and decreased by Rs. 15000 after 4 months
B invested = Rs. 88000 when A decreased his capital
Formula:

Calculation:
Person

A

B

Amount

63000 and 48000

88000

Time

4 and 8

8

Total money invested by A = 63000 × 4 + 48000 × 8
Total money invested by B = 88000 × 8
Required ratio = 63 × 1 + 48 × 2 ∶ 88 × 2
⇒ 63 + 96 ∶ 176
⇒ 159 ∶ 176
∴ The ratio of their profit after 1 year is 159 ∶ 176.
