Cash Price of Sewing Machine =  1470.68 Rs

Step-by-step explanation:

Down Payment = Rs 500

Remaining amount to Pay = P Rs

Rs 1000 Paid in 5 month

=> EMI = 1000/5 = 200 Rs

Interest Rate = 12 % per annum = 1 % Per month

n = 5 month

EMI = P *  (R/100)  ( 1 + R/100)ⁿ/ ( ( 1 + R/100)ⁿ - 1)

=> 200 = P * (1/100)  * 1.01⁵ /(1.01⁵ - 1)

=> P = 970.68

Cash Price of Sewing Machine = 500 + 970.68

= 1470.68 Rs

Cash Price of Sewing Machine =  1470.68 Rs

Answer:

 

- 1452.38 Rs ( Rounded figure )

* if interest charged is Simple interest

Step-by-step explanation:

Since Mr. Aslam pays Rs.500 as down payment and Rs.1000 in 5 months.

The interest should be charged on Rs.1000 over 5 months at a rate of 12% per annum.

*interest is not charged on down payment in a typical transaction.

Hence we can form the equation:

x + (12/100) (x) (5/12) = 1000

Formation: The amount of interest charged per annum on principle amount in the time ( years ) + the principle amount is equal to 1000.Rs

here;

- x is taken as a variable for the principle amount

- 12% = 12/100 is the interest charged

- 5/12 ( 5 months / 12 months ) is the time taken in years ( since there are 12 months in a single year )

Solving:

x + 0.05x = 1000

1.05x = 1000

x = 1000/1.05

x = 952.38 ....

adding principle amount and down payment to get the price of the machine without interest.

952.38 + 500 = 1452.38

- so it costs 1452.38 Rs
