The capital invested by the man was Rs. 10,000.

Step-by-step explanation:

Capital invested by the man be denoted as “x”.

The man’s annual income at simple interest is given as Rs. 965

Simple Interest =  P x R X t / 100

Now by using the formula

2/5x x 8 x 1 /100 + 3/8x x 10 x 1 /100 + (1- 2/5 - 3/8)x x 12 x 1/100 = 965

2/5x x 8 /100 + 3/8x x 10/100 + 9/40x x 12/100 = 965

16x /5 + 30x /8 + 108x/40 = 965 x 100

128x + 150x + 108x/40 = 96500

386x  = 96500 x 40

x = 3860000/386

x = 10,000

Thus, the capital invested by the man was Rs. 10,000
