What annual instalment will discharge a debt of Rs.9,600 due in 5 years at 10% simple interest?
Answer & explanation
Correct answer: option 4
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
