Explanation:

Interest for A = 42000×7×1/100 = Rs. 2940
Interest for B = 48000×7×1/100 = Rs. 3360
Interest for C = 32000×7×1/100 = Rs. 2240
Total interest of (A+B+C) = (2940+3360+2240) = Rs. 8540
Remaining profit = Rs. (32940-8540) = Rs. 24400
A : B : C
Capital→ 42000 : 48000 : 32000
21 : 24 : 16
According to the question,
(21+24+16) units = Rs. 24400
61 units = Rs. 24400
1 units = Rs. 400
Hence, share of A in remaining profit = 400 × 21 = Rs. 8400
Share of B in remaining profit = 400 × 24 = Rs. 9600
Share of C in remaining profit = 400 × 16 = Rs. 6400
∴ Total share of A = 8400 + 2940 = Rs. 11340
