Correct Answer - Option 2 : Rs. 8000
Given:
Total principal = Rs. 17600
Rate = 6% and 5%
Time = 2 years
Formula Used:
S.I = PRT/100
Where,
S.I = Simple interest, P = Principal,
R = Rate of interest, T = Time duration
Calculation:
Let the principal at the rate of 6% and 5% be x and (17600 - x) respectively,
According to the question, we have
(x × 6 × 2)/100 = {(17600 - x) × 5 × 2}/100
⇒ 12x = 176000 - 10x
⇒ 22x = 176000
⇒ x = 8000
∴ The principal at the rate of 6% is Rs. 8000.
