Correct Answer - Option 1 : Rs.6000
Given:
Principal (P1) = 5000, Rate (R1) = 12%, Time (T) = 4 years
Principal (P2) = x, Rate (R2) = 10%, Time (T) = 4 years
Formula Used:
Simple Interest (I) = (P × R × T)/100
Where,
P → Principal
R → Rate
T → Time
Calculations:
Simple interest gained from 5000 = (5000 × 12 × 4)/100 = 2400
Let the other Principal be x.
S.I. gained = (4800 – 2400) = 2400
⇒ (x × 10 × 4)/100 = 2400
⇒ x = Rs. 6000
∴ The correct answer is Rs. 6000.
