Question

A PC can be bought by making monthly payments of AED 125 at the end of the month for 2 years.

The first payment is usually due one month after the purchase of the PC. The Company has made a special offer for Ramadan and the first payment is due at the end of the month 2 months after the PC is purchased. The financing cost is 24% compounded monthly.

What is the purchase price of the PC?

Answer 1

you have to find out the actual value of your monthly payments
Va = 125(1/1.02^2+...+1/1.02^26)= 125*(1/1.02^27-1/1.02)/(-0.02)=2392.58
=2392.58
