Question
Kiran lent Rs. 40,000 to a friend at a compound interest
rate of 'b%' per annum, compounded annually. After one year, the friend returned Rs. 44,800. If Kiran had lent the money at simple interest of (b + 2)% per annum instead, how much interest would he have earned?Solution
ATQ, Determine the compound interest rate 'b': 
Compute the simple interest: 
The interest earned would have been Rs.5600.
(804/65) ÷ (11/798) × (129/131) = ?
1254.04 – 440.18 + 399.98 ÷ 10.06 = ?
( 19.95%  of 799.89 ) × 12.05 = ? 2 + 18.99 × 6250 ÷ 1250
