Correct Answer - Option 3 : 50
Given:
Profit = 200%
Cost increases = 50%
Formula used:
S.P. = C.P. + Profit
Calculation:
Assuming original C.P. to be Rs. 100
⇒ Profit = Rs.200 (∵ Profit = 200% of C.P.)
⇒ S.P = 100 + 200
⇒ S.P. = 300
⇒ New C.P. = 100 + (0.5 × 100)
⇒ New C.P. = 150
⇒ New Profit = 300 - 150
⇒ New profit = 150
⇒ Required profit = (150/300) × 100
⇒ Required profit = 50%
∴ Required profit is 50%
