Question

13)A shopkeeper gains 7% by selling a article for Rs 3852. If he sells it for 4050. find his gain percent​

Answer 1

Given :-

S.P= Rs.3852

Profit = 7%

To Find :-

What is his gain Percent ?

Solution :-

$c.p = \frac{100}{100 + profit\%age\: } \times s.p \: \\ = \frac{100}{100 + 7} \times 3852 \\ c.p = rs.3600 \: and \: s.p = 4050$

Profit = S.P - C.P

= Rs. 4050 - Rs. 3600= Rs. 400

$profit\% \: age \: = \frac{profit \:}{c.p} \times 100$

$= > \frac{450}{3600} \times 100 = \frac{50}{4}$

= 12.5%

Hence

12 and 1/2

1/2 = half that is 0.5

hence the total answer is 12.5%

Answer 2

Answer:

107% = 3852(SELLING PRICE)

1%= 3852 / 107

1%= 36

100%=3600(COST PRICE)

=> PROFIT% = (4050-3600)/3600 *100

                     = 450/36

                     = 12.5%(Answer)
