SP=18000

Loss%=20%

⟹

CP

CP−SP

×100=20

⟹

CP

SP

=

5

4

CP=

4

5

×18000=5×4500=22500

Profit%=10%

⟹

CP

SP−CP

×100=10

22500

SP−22500

×10=1

SP−22500=2250

SP=22500+2250=24750

Answer 2

Answer:

Let x be the cost price.

Sale price with loss = x * 96.5/100 = 0.965x

Sale price with profit = x * 109.5/100 = 1.095x

Now , 1.095x — 0.965x = 0.13x = 2054

Hence, x = 2054/0.13 = Rs. 15800

So, sale price with 15 % profit = 15800 * 115/100 = Rs. 18170
