Answer» Correct Answer - Option 4 : Rs. 48,400

Given:

Amount of a bike (P) = Rs. 84000

Rate of interest = 10%

Formula used:

P × {1 + (R/100)}2 = I × {1 + (R/100)} + I

Where p = principal

R = rate percentage at compound interest

I = each installment

Calculation:

84000 × {1 + (10/100)}2 = I × {1 + (10/100)} + I

⇒ 84000 × (11/10) × (11/10) = I × (11/10) + I

⇒ 840 × 11 × 11 = (21/10) × I

⇒ I = (840 × 10 × 11 × 11)/21

⇒ I = 48400

∴ The value of each installment is Rs. 48,400
