Correct Answer - Option 1 : Rs 110
Given
Selling Price = Rs. 121, Profit = 10%
Formula used
S.P = C.P × (100 + Profit%)/100
If there is a loss, then
S.P = C.P × (100 – Loss%)/100
Calculation
S.P = C.P × (100 + Profit %)/100
S.P = C.P × (100 + 10%)/100
⇒121 = C.P × 110/100
⇒ C.P = 110
∴ Cost Price is Rs. 110
