Question

Answer 1

Hello dear !

Given :-

buying 15 at Rs. 21

Selling 20 oranges at Rs. 25

to find:-

Gain or loss percentage

Solution:-

$\large\underline{\boxed{\bf\green{C.P}}}$

first let's find the Cost Price of the Oranges

=> Cost of 15 oranges = 21Rs.

=> Cost of 1 orange = 21/15 = 1.4 Rs.

$\large\underline{\boxed{\bf\green{S.P}}}$

Now let's find the Selling price of the Oranges.

=> Cost of 20 oranges = 25Rs.

=> Cost of 1 orange = 25/20 = 1.25 Rs.

since, CP>SP

so, loss of :-

1.4 - 1.25 = 0.15 Rs

we can clearly observe that it is a Loss of 0.15Rs.

now we have to find the Loss percentage..

by using the formula :-

$\large\underline{\boxed{\bf\blue{Loss \% = \dfrac{Loss}{C.P} \times 100}}}$

substituting the values.:-

loss % = 0.15/1.4 × 100 = 10.7

Hence, there is a Loss of 10.7%
