A man wants to sell his scooter. There are two offers, one at Rs. 12,000 cash and the other a credit of Rs. 12,880 to be paid after 8 months, money being at 18% per annum. Which is the better offer?
Rs. 12,000 in cash
s. 12,880 at credit
Both are equally good
Answer: Option
Explanation:
P.W. of Rs. 12,880 due 8 months hence
= Rs. 12880 x 100
100 + 18 x 8
12
= Rs. 12880 x 100
112
= Rs. 11500.

S.I= (P*T*R)/100.
for P=12000,

S.I = 1440,
Total amount = P+S.I = 13440.
for what present value of P,
The total amount will be=12880 after 8 months with 18% interest is calculated using the formula
P.W= (P * 100)/ 100+ (R*T).

Pv = Fv/(1+n*r) simple interest,
Pv = 12880/(1+.18/12*8),
= 12880/1.12,
PV = 11500.

The question is which one is a better option for the seller not for the buyer, so if he sells it for cash of Rs. 12000 but if he sells for credit he will only receive only Rs. 11500 (solved using formula).

Hence better option is to sell it for cash.
