Step-by-step explanation:
Given
A man invested 1/3 of his capital at 7 percent and 1 /4 at 8 percent and the remainder at 10 percent p a if his annual income is Rs 561, the capital is
- Let the total capital be Rs x
- So x/3 x 7 x 1 / 100 + x/4 x 8 x 1 / 100 + (1 – 1/3 – 1/4)x x 10 x / 100 = 561
- 7x / 3 + 2x + 5x / 12 x 10 = 561 x 1001 x
- 14 x + 12 x + 25 x / 6 = 561 x 100
- 51 x = 561 x 100 x 6
- Therefore x = 336600 / 51
So x = Rs 6600
