Question

A dealer sold a camera for rs 1080 gaining 1/3 of its cost price. Find(i) the cost price of the camera, and (ii) the gain per cent earned by the daeler.

Answer 1

Therefore, the cost price of the camera is Rs. 680 and the gain percent earned by the dealer is 33.33%

Explanation:

Selling price of the camera (S.P.) = Rs. 1080

Gain = 1/3 of S.P. = 1/3×(Rs. 1080) = Rs. 360

(i) cost price of the camera (C.P.) = ?

(ii) gain percent earned by the dealer = ?

Solution:

(i) C.P. = S.P.-Gain = Rs. 1080-Rs. 360 = Rs. 680

Again,

(ii) Gain percent =(Gain/C.P.)×100% = (360/1080) ×100٪

= 33.33%
