Humayra borrowed Tk. 240, free of interest, to pay for her new hair band. If she pays back 20% of the amount each month and has already paid back Tk. 120. how many months have passed since she took the loan?

A 3 months
B 3.5 months
C 2.5 months
D 2 months

Correct Answer: 2.5 months

As She pays 20% of the amount each month So, 20% of 240 = 20/100 × 240 = 48 tk She paid back 120 tk So, remaining (240 - 120) = 120 48 tk pays back in 1 month So, 120 tk pays back in 120/48 = 2.5 months (ans)
