Best answer
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.
