Correct Answer - Option 4 : Rs. 12,950
Given:
Investment of Rahul = Rs. 16000
Investment of Mohit = Rs. 20000
Total profit = Rs. 1,55,000
Formula:
Profit = investment × time period
Calculation;
Ratio of profit of Rahul and Mohit
= [(16000 × 4 ) + ( 16000 + 4000 ) × 8 ] ∶ [(20000 × 4 ) + ( 20000 + 4000 )× 8]
⇒ 56 ∶ 68
⇒ 14 ∶ 17
Profit share of Rahul = 155000 × 14/31 = Rs. 70,000
Profit share of MOhit = 155000 × 17/31 = Rs. 85,000
Now, equivalent CI of two year at the rate of 20%
⇒ 20 + 20 + ( 20 × 20 )/100 = 44%
Equivalent CI of two year at 10%
⇒ 10 + 10 + (10 × 10)/100 = 21 %
Difference between compound interest got by Rahul and Mohit
=( 70000 × 44/100 ) – ( 85000 × 21/100 )
⇒ 30800 – 17850 = Rs. 12,950
∴ Difference between interests got by both at the end of two year is Rs. 12,950
