A woman buys an item for Rs. 950 and sells it for Rs. 1,150. What is her percentage profit (rounded off to the nearest integer) ?

Correct option is A

Given:
Cost Price (C.P.) = ₹950
Selling Price (S.P.) = ₹1150
Formula Used:
Profit = S.P. – C.P.
​$$\text{Profit \%} = \left(\dfrac{\text{Profit}}{\text{C.P.}}\right) \times 100$$​​
Solution:
Profit = 1150 – 950 = ₹200
​$$\text{Profit \%} = \left(\dfrac{200}{950}\right) \times 100 \\[8pt]= \dfrac{200 \times 100}{950} \\[8pt]= \dfrac{20000}{950} \\[8pt]= 21.05\% \;\;\approx\;\; 21\%$$​​
