• A. Rs. 10800
• B. Rs. 11500
• C. Rs. 11700
• D. Rs. 12250

Answer 1

The correct option is C Rs. 11700

Let the investments of A, B and C be =2x,3x and 4x
Let the returns on their investments be =7y,6y and 5y
Their earnings will be =14xy,18xy,and 20xy
Now,20xy-18xy=2xy=450
Total earnings $=52xy=450\times 26=Rs.11700$
