Question

By selling a radio for ₹528,mohit gain10% find the cost price

Answer 1

SP = 528
gain = 10%

let CP be x
=> x +x×10/100=528
=> x+x/10=528
=> 11x/10=528
=> x= 528×10/11
=> x= 480

Answer 2

cp =x
sp =
$x + \frac{10}{100} \times x = 528$
$= > \frac{110}{100} \times x = 528$
$= > x = 528 \times \frac{10}{11}$
$= > x = 48 \times 10 \\ = > x = 480$
so the cp is rs 480
