Question
Ankur invests Rs. 9,250 at 8% p.a. for 3 years on simple
interest. The amount he gets back is Rs. '2k'. Find the product of digits of 'k'.Solution
ATQ,
Simple interest = Principal × Rate × Time ÷ 100
Interest = 9,250 × 8 × 3 ÷ 100 = Rs. 2,220
2k = 9,250 + 2,220
2k = 11,470
k = 5,735
Product = 5 × 7 × 3 × 5 = 525
