Question

A man bought oranges at 25 for Rs.100 and sold them at 20 for Rs.100. Find his gain or loss percent.

Answer 1

CP of 25 oranges = 100

SP of 20 oranges = 100

SP of 25 oranges = 100/20 × 25 = 125

gain = 125-100 = 25

gain % = 25/100 × 100 = 25%

Answer 2

Answer - $\bold{Gain \: Percentage \: = 25 \%}$


Explanation -

Given :

CP of 25 oranges = Rs 100

SP of 20 oranges = Rs 100



Finding the CP of 1 orange -

25 oranges = ₹ 100

1 orange = 100/25 = 4

CP of 1 orange = ₹ 4


Finding the SP of 1 orange -

20 oranges = ₹ 100

1 orange = 100/20 = 5

SP of 1 orange = ₹ 5


Here, SP is more than CP. Hence, it is Gain.

Gain = SP - CP

Gain = 5 - 4

Gain = 1


Finding Gain Percentage -

Gain Percentage = (Gain/CP) x 100

= (1/4) x 100

= 25 %


Hence :

$\bold{Gain \: Percentage \: = 25 \%}$
