Question : A moneylender claims to lend money at the rate of 10% per annum simple interest. However, he takes the interest in advance when he lends a sum for one year. At what interest rate does he lend the money?
Option 1: $10$%
Option 2: $10\frac{1}{9}$%
Option 3: $11$%
Option 4: $11\frac{1}{9}$%
Correct Answer: $11\frac{1}{9}$%
Solution : Given: Rate = 10% Let the amount lent be Rs. 100. Interest =10% of 100 = Rs. 10 Actual amount = 100 – 10 = Rs. 90 Actual rate = $10×\frac{100}{90}=11\frac{1}{9}$% Hence, the correct answer is $11\frac{1}{9}$%.
