Answer 1

SOLUTION

GIVEN

• Amir expects a gain of 24% on his cost price

• In a week, his sale was of Rs. 620,

TO DETERMINE

The profit

EVALUATION

Let C be the cost price

Here it is given that Amir expects a gain of 24% on his cost price

So the profit price

$= \displaystyle \sf{C \times \frac{24}{100} }$

$= \displaystyle \sf{ \frac{24C}{100} }$

So the selling price

$= \displaystyle \sf{ C + \frac{24C}{100} }$

$= \displaystyle \sf{ \frac{124C}{100} }$

So by the given condition

$\displaystyle \sf{ \frac{124C}{100} = 620}$

$\implies \displaystyle \sf{ C = 620 \times \frac{100}{124} }$

$\implies \displaystyle \sf{ C = 5 \times 100 }$

$\implies \displaystyle \sf{ C = 500 }$

So the cost price = Rs 500

Now selling price = Rs 620

Hence the profit

= Rs ( 620 - 500 )

= Rs 120
