A man invested 1/3 of his capital at 21%;1/4 at 16% and remainder at 10%. If his income is Rs 2002 then what is his capital?

Let Capital = X Then, we can write the following equation:

X/3 x 0,21 + X/4 x 0,16 + 5X/12 x 0,10 = 2002

Solving this equation X = Rs 13200

A invested 1/3 of his capital at 7%, 1/4 at 8% and remainder at 10%. If his annual income is Rs.1122, then what is capital?
