Answer 2

Answer:

Rs 198

Step-by-step explanation:

Given,

S.P. of a doll is Rs 220. Rate of profit is 10%.

To find,

C.P. of the doll.

Procedure,

$C.P. = \frac{100 - gain\%}{100} \times S.P.$

$C.P. = \frac{100 - 10}{100} \times 220$

$C.P. = \frac{90}{100} \times 220$

$C.P. = \frac{90 \times 220}{100}$

$C.P. = \frac{19800}{100}$

$C.P. = 198$

Therefore, the C.P. of the doll is Rs 198
