Correct Answer - Option 3 : Rs.1512
Given:
Principal (P1) = Rs.4200, Amount (A) = Rs.5523
Rate (R) = 8.75%, Principal(P2) = Rs.4800
Formula used:
S.I. = (P × R × T)/100
Where, S.I. → Simple Interest
P → Principal
R → Rate
T → Time
Calculations:
Let time be T.
S.I. = A - P1
⇒ S.I. = 5523 - 4200 = Rs.1323
So, 1323 = (4200 × 8.75 × T)/100
⇒ T = (1323 × 100)/(42 × 875)
⇒ T = 3.6 years
Now,
P2 = Rs.4800, T = 3.6 years, R = 8.75%
Thus S.I. = (4800 × 3.6 × 8.75)/100
⇒ S.I. = Rs.1512
∴ S.I. is Rs. 1512.
