Question:

What annual instalment will discharge a debt of Rs.9,600 due in 5 years at 10% simple interest?

Options:

Rs.1450

Rs.1550

Rs.1500

Rs.1600

Correct Answer:

Rs.1600

Explanation:

Let equal installment = 100 Rs

Rate=12%

Payable amount in First year= Principal = Rs 100 

Payable amount in second year = Principal + Interest

                                             = 100 + 10% of 100

                                             = 100+ 10

                                             = Rs 110

Payable amount in third year = Principal + Interest

                                          = 100 + 20 % of 100

                                          = 100+ 20

                                          = Rs 120

Payable amount in fourth year = Principal + Interest

                                              = 100 + 30 % of 100

                                              = 100+ 30

                                              = Rs 130

Payable amount in fifth year = Principal + Interest

                                          = 100 + 40% of 100

                                          = 100+ 40

                                          = Rs 140 

So payable amount after 5 years =

100 + 110 + 120 + 130 + 140 = Rs 600

ATQ

600 unit = 9600 Rs

1 unit = 16

∴ 100 unit = Rs 1600
