Question
Anjali invested Rs. 9,150 at a simple interest rate of 4%
p.a. for 5 years. If she receives Rs. '2n' in total, what is the product of all digits in 'n'?Solution
ATQ,
Simple interest = Principal × Rate × Time ÷ 100
Interest earned = 9,150 × 4 × 5 ÷ 100 = Rs. 1,830
2n = 9,150 + 1,830
Or, 2n = 10,980
Or, n = 5,490
Required product = 5 × 4 × 9 × 0 = 0
