Correct Answer - Option 1 : (a), (b) are correct

Given:

A's share = Rs. 16000

B's share = Rs. 12000

C's share = Rs. 21000

Total profit = Rs. 26400

Calculation:

A's share = Rs. 16000

B's share = Rs. 12000

C's share = Rs. 21000

A's investment in 3 months = 3 × 16000 = Rs. 48000

After 3 months A withdraw Rs. 5000

A's final profit in one year = 48000 + 9(16000 - 5000) = Rs. 147000

B's investment in 3 months = 3 × 12000 = Rs. 36000

After 3 months B invested Rs. 5000 more

B's final profit in one year = 36000 + 9(12000 + 5000) = Rs. 189000

C invest after 6 months = 6 × 21000 = Rs. 126000

The ratio of three shares = 147000 : 189000 : 126000 = 7 : 9 : 6

Total share = 22

Total profit = Rs. 26400

Difference between B's and C's profit =  (9 - 6)/(22) × 26400

Difference between B's and C's profit = (3/22) × 26400 = Rs. 3600

Share of A = (7/22) × 26400 = Rs. 8400

a and b are correct statement

∴ The correct answer is option 1.
