Question

Find the selling price, if : (i) C.P. = Rs. 352; overheads = Rs. 28 and profit = 20%. (ii) C.P. = Rs. 576; overheads = Rs. 44 and loss = 16%.

Answer 1

C.P. = Rs. 352
Overheads = Rs. 28
Net C.P. = Rs. 352 + Rs. 28 = Rs. 380
Profit = 20%
We know : S.P. = $\frac{(100+gain}{100}\times$ C.P.
= $\frac{(100+20)}{100}\times Rs.380=Rs.\frac{120}{100}\times 380$
= 12 $\times$ 38 = Rs. 456
(ii) C.P. = Rs. 576
C.P. = Rs. 576
Overheads = Rs. 44
Net C.P. = Rs. 576 + Rs. 44
= Rs. 620
Loss = 16%
We know : S.P. = $\frac{(100-Loss}{100}\times C.P.=\frac{(100-16)}{100}\times Rs.620=Rs.\frac{84}{100}\times 620$
= Rs. $\frac{5208}{10}$ = Rs. 520.80
