Question

A shopkeeper bought 15 hair clips for ₹10 each and sold 12 hair clip for ₹18 each. find gain or loss% .​

Answer 1

${\small{\bold{\purple{\underline{Answer}}}}}$

The gain percentage is 21%.

A shopkeeper bought 11 clips for Rs.10 .

He sold 10 clips for Rs.11 .

Cost price of 1 clip will be Rs. $\frac{10}{11}$ .

Selling price of 1 clip will be Rs. $\frac{11}{10}$ .

Now the gain percentage is given by

Gain percentage = $\frac{Gain}{Cost\ price}$ × 100

Gain = Selling price - Cost price

Now Gain = $\frac{11}{10} - \frac{10}{11}$

Gain percentage = $(\frac{\frac{11}{10} - \frac{10}{11}}{\frac{10}{11} })$ × 100

Gain percentage = $(\frac{121 - 100}{110 } . \frac{11}{10})$ × 100

Gain percentage = 21 %

Answer 2

Answer

He bought 15 hair clips at 10 ₹ each

that means,,, CP = 10×15 = ₹150

SP = 12×18 =216

.

. .

Gain = SP-CP

= 216-150

= 66

Gain% = Gain/Cp×100

= 66/150×100

After Calculating= 44%

He gains at 44%
