A toy is sold for Rs. 220, what was the cost if the rate of profit was 10% of the cost?
Explanation
Given Data
S.P = 220 Gain=10% C.P=?
We know that :
S.P=[ 100 +Gain]/100 * C.P
We Have to find C.P, so re-arrange the formula
⇒ C.P= 100/[ 100 +Gain] * S.P
Putting given data:
⇒ C.P= 100/[ 100 +10] * 220
⇒ C.P=200
