Correct Answer - Option 3 : 1500, 1800
Given:
The income of R and S ratio = 10: 12
And expenditure ratio = 10: 16
Each saves = Rs. 1000
Formula used
Income = expenditure + saving
Calculation
Let Income = 10x and 12x
Then
Income – saving = expenditure
In ratio terms,
(10x - 1000) ÷ (12x - 1000) = 10 ÷ 16
160x – 16000 = 120x – 10000
40x = 6000
x = 150
Therefore, then their incomes R = 1500 and S = 1800
Hence, their incomes R = 1500 and S = 1800
