Question

by selling a toy for rs 35 a man gains 25%.find cp

Answer 1

Hi ,

selling price of the toy = s.p = Rs 35

gain= g = 25%

let cost price = c.p

c.p = ( s.p × 100 ) / ( 100 + g )

= ( 35 × 100 ) / ( 100 + 25 )

= ( 35 × 100 ) / 125

= ( 35 × 4 ) / 5

= 7 × 4

c.p = Rs 28

I hope this helps you.

:)

Answer 2

let the cost price of the toys be x
therefore,
... profit%=S.P. - C.P/C.P*100
25=35-C.P/C.P*100
therefore, 1/4=35-C.P/C.P
therefore, C.P=140-4C.P. (Cross-multiplication)
therefore, 5C.P=140

hence, C.P=140/5=₹28
