in a deal of tv with selling price of 50000, a customer can purchase it for cash down payment of 10000.

and balance in 12 monthly installments of 3800

calculate flat rate and effective rate..

soln..( as per me)

selling price 50000

cash down payment 10000

balance in 12 monthly installments of 3800

Amt = 12* 380 = 45600

i.e interst 5600

flat rate 5600/40000 = 14%( this soln is correct)
