Question

Jayanti buys oranges at 3 for 80 paise and sells 5
for 1.50. How many oranges should she sell to
earn a profit of 10?​

Answer 1

Step-by-step explanation:

Given,

cost price of 3 oranges = 80paise =80/100 =0.8 rupees

then,

cost price of 1 orange = 0.8/3 = 0.2

therefore, CP of 1 orange = 0.2

profit = 10

then , SP = CP + Profit

SP = 0.2+10 =10.2

If SP of 1 pen =1.5/5 = 0.3, then

SP of no of pens = 10.2

no.of pens = x

then, x=10.2/0.3

=34

therefore no.of pens to be selled =34
