Question

1. If a shopkeeper sells an article for 2640, he incurs a loss of 12%. What should the selling price be
in order to gain 12%?
2. If an item is sold for 990 at a profit of 10%, then find its CP.
if CP is 1500 and SP is 3 times CP, what is the profit?
13​

Answer 1

Answer:

S.P. of an article = Rs. 2640

Gain = 10%

(i) ∴ C.P. = (S.P. × 100)/(100 + gain%)

= Rs. (2640 × 100)/(100 + 10)

= Rs. (2640 × 100)/110

= Rs. 2400

(ii) In second case, Gain = 15%

∴ S.P. = {C.P. (100 + gain%)}/100

= Rs. {2400(100 + 15)}/100

= Rs. (2400 × 115)/100

= Rs. 2760

Answer 2

Answer:

1) Selling price(SP) = 2640

Profit% (P) = 10%

P= SP-CP/CP*100

10= 2640-CP/CP*100

CP= 26400-10 CP

11 CP= 26400

CP= 2640/11

CP= 2400

Cost price of article= Rs. 2400
