Question

By selling a toy for rupee 25 , a man gains 25%. find the CP of the toy

find the answer ​

Answer 1

CP=Rs 20

Explanation:

Selling price=Rs 25

Gain percent=25

then,

Cp =100*25/100+25

Cp=2500/100+25

Cp=2500/125

CP=Rs 20

Answer 2

CP = ₹ 20

Explanation:

Finding the Cost price:

`\sf \boxed{CP =(100 )/((100+gain \ percent))*SP}`

Gain % = 25%

SP = ₹ 25

`\sf CP = (100)/(100+25)*25\\\\ CP = (100)/(125)*25`

= ₹ 20
