Answer 1

Answer:

Here is your answer

Explanation:

Profit = S.P. - C.P.

Let the cost price be C.

The selling price:

= 10% discount

= discount price = 100%(marked price) - discount (10%) = 90%

= 90%/100% × 22000

= 0.9 × 22000

= Rs. 19800

This discount price is the S.P.

Therefore profit = 19800 - C

% profit = profit/ cost price ×100%

= 19800-c/ c ×100% = 20%

= 100(19800-c)/c = 20

= 100(19800-c)/c = 20

= 1980000 - 100c = 20c

= 120c = 1980000

= c = 1980000/120

c = Rs. 16500
