Step-by-step explanation:
Total no. of bulbs bought = 250
C.P of each bulb = ₹10
Total C.P of all bulbs = ₹10x250 = ₹2500
A/Q, 12 bulbs get fused
Remaining bulbs = 250-12 = 238
S.P of each bulb = ₹12
Total S.P of all bulbs = ₹12x238 = ₹2856
Gain = S.P - C.P
Gain = ₹2856- ₹2500
Gain = ₹356
Gain% = Gainx100/C.P.
Gain% = 356x100/2500
Gain% = 14.24%
