Question

By selling 130 cassettes, a man gain amount equal to the selling price of 5 cassettes find the gain percent

Answer 1

✦Answer ✦


Let the selling price of a cassettes = x Rs

so , selling price of 130 cassettles = 130 Rs

selling price of 5 cassettles = 5x

so

✺according to given condition .

(a man gain amount equal to the selling price of 5 cassettes )


=>profit = 5x


✺ FORMULA .....


✺PROFIT = S.P - C.P


=> 5x=130x-c.p

=> c.p= 125x

=>
cost of 130 cassettles =125x

cost of 1 cassettles =
$\frac{125}{130} x$


= 0.96 x Rs (approx)


profit of each cassettles =


s.p of 1 cassettles- c.p of 1 cassettles

$x- 0.96x$


=0.04x Rs



✺profit %


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


=>
$\frac{0.04 \: x}{x} \times 100$




$= > 4\%$

Answer 2

Solution :-

let the cost price of each cassette be rs.10

cost price of 130 casts = 130× 10=1300

by selling , he gained sp of 5 cassettes

therefore , cost price of 130 cassettes = selling price of 125 cassettes

sp of 5 cassettes = 1300/125 × 5 = 52

he gained Rs. 52 on selling 130 cassettes

gain℅= gain/total cp × 100

=> 52/1300× 100

=> 4℅ Ans.
