Question

Sarthak bought 20 chairs for Rs.3200 and spent Rs.400 on cartage. He sold 15 of them for Rs220 each. For how much should he sell each of the remaining chairs so as to gain 25% on the entire transaction? (Ans is 240, I need the steps to solve it)

Answer 1

Answer:

240

Step-by-step explanation:

Sarthak Purchased 20 chair for 3200 and 400 for cartage so the Cost price will be 3600

Then he sold 15 chairs for 220 each = 15x 220 = 3300

Let the rest he sold for x rupees each

Profit% = (Selling price- Cost Price)/ Cost price x 100

So, (3300 + 5x -3600)/ 3600x 100 = 25

by solving the equation we get x= 240

Answer 2

Answer:

Rs. 240

Step-by-step explanation:

CP = 3200 + 400 = 3600

25% of 3600 = 25/100 x 3600 = 900

SP = 3600 + 900 = 4500

SP of the 15 chairs at Rs. 220 each = 15 x 220 = 3300

4500 - 3300 = 1200

SP of the remaining chairs = 1200/5 =Rs. 240
