Correct Answer - Option 1 : 15%
Given
Principal = Rs 3000
Interest after 2 year = Rs 750
Formula Used
Simple Interest = (Principal × Rate × Time)/100
Calculation
⇒ Total interest = interest in 1st year + interest in 2nd year
⇒ 750 = (3000 × 10 × 1/100) + (3000 × x × 1/100)
⇒ 750 = 300 + 30x
⇒ x = 450/30 = 15%
∴ The value of x is 15%
