Question

A dealer purchase 250 bulbs for RS 10 however 12 bulbs were found defective so he threw them away he sold the remaining bulbs for RS 12 each find his gain or loss percent

Answer 1

Answer:

wrong question. it should be 250 bulbs for rs 10 each.

cp of 1 bulb=rs10

cp of 250 bulbs= 250*10=rs 2500

remaining bulbs after he threw away 12= 250-12= 238 bulbs

sp of 1bulb= rs12

sp of 238 bulbs= 238*12 = rs2856

sp>cp

then profit = sp-cp= 2856-2500=rs 356

now profit%= profit/cp *100

= 356*100/2500

=14.24% or 14 6/25 %

hope this help
