Question

By selling an article for 1680 a man gains 12% find the cost price​

Answer 1

S.P. = Rs. 1, 128, Profit = 12%

C.P. = (100)/(100 + Profit) × S.P.

∴ C.P. = 100/(100 + 12) × 1680

= (100 × 1680)/112 = (25 × 1680)/28 = 25 × 60 = Rs. 1500

(ii) S.P. = Rs. 1, 128, Loss 6%

C.P. = 100/(100 – Loss) × S.P.

∴ C.P. = (100 × 1128)/(100 – 6) = (100 × 1128)/94 = 100 × 12

= Rs. 1200
