A shopkeeper purchased 200 bulbs for rs.10 each , how ever 5 bulbs are fused and had to be thrown away and the rest were sold at rs.12 each find the gain or loss
Answers
Step-by-step explanation:
bulbs purchased = 200
cost of each bulb = 10
cost of 200 bulbs = 200* 10
= 2000
no of bulb fused = 5
lose of 5 bulb. = 5*10
= 50
sp of bulb = 12
cost of 195 bulbs = 195 * 12
= 2340
note as 5 bulbs are fused we don't concerned about them
loss or profit =CP - SP
= 2000 - 2340
= 340
there fore he earned a profit of 340
Total no. of bulbs purchased by the shopkeeper=
200bulbs
Cost of each bulb = Rs. 10
So, cost of 200 bulbs= 200×10= Rs. 2000
No. of bulbs that were fused = 5
So 200-5= 195
SP ( selling price ) = 195×12= Rs. 2340
Here SP>CP, 2340>2000
there's a profit.
Profit= SP-CP (selling price-cost price)
= 2340-2000
= Rs. 340
Profit % = profit/CP× 100
340/2000× 100
= 17%
