Question

A photograph offered to supply 3 copies of photograph
for RS 20and 12copies for RS 50; his profit are RS 8 and RS 18 respectively, for what sum should he supply 30 copies in order to make a profit of RS 26?​

Answer 1

Find the cost price for 12 copies for Rs 60:

Profit = Rs 5

Cost Price = 60 - 5

Cost Price = Rs 55

Find the cost price for 20 copies for Rs 80

Profit = Rs 7

Cost Price = 80 - 7

Cost Price = Rs 73

Find the variable cost price for 1 piece:

Cost Price for 12 pieces = Rs 55

Cost Price for 20 pieces = Rs 73

(20 - 12) pieces = 73 - 55

8 pieces = Rs 18

1 piece = Rs 2.25

Find the fixed cost:

Total cost for 12 piece = Rs 55

Variable cost for 12 pieces = 12 x 2.25

Variable cost for 12 pieces = Rs 27

Fixed cost = 55 - 27

Fixed cost = Rs 28

Find the cost of 30 copies:

30 copies = 28 + 30(2.25)

30 copies = Rs 95.50

Find the selling Price:

Profit = Rs 10

Selling Price = 95.50 + 10

Selling Price = Rs 105.50
