Answer 2

Correct Question:-

Rohan sold a toy for 220 making a profit of 10%. Find the C.P. of the toy.

Answer:-

Given:-

• Rohan sold a toy for Rs. 200
• He made a Profit of 10%

Solution:-

Formula need:-

$\boxed{\boxed{ \sf{C.P. = \dfrac{100}{(100 + gain\%)} \times S.P.}}}$

Therefore,

According the question,

$C.P. = \dfrac{100}{(100 + 10\%)} \times 200$

$= \dfrac{100}{110} \times 220$

( dividing 220 and 110 )

$= 100 \times 2$

$= Rs.200$

Therefore, Cost Price is Rs. 200

Required Answer:-

• The Cost Price of the toy is Rs. 200

☆ Remember:-

• If S.P. > C.P. then, Gain = S.P. - C.P.

• If C.P. > S.P. then, Loss = C.P. - S.P.

• When, S.P. and Loss% is given

$C.P. = \dfrac{100}{(100 - loss\%)} \times S.P.$

• When, S.P. and gain is given

$C.P. = \dfrac{100}{(100 + gain\%)} \times S.P.$
