Question

7. A shopkeeper buys 15 changes for Rs21 and sells them at 20 oranges for Rs25. Find his gains or loss percentage.​

Answer 1

Answer:

Loss of 7 % approx

Step-by-step explanation:

C.P for 15 orange = 21 Rs.

C.P for 1 Orange = 21/15 or 7/5 rupees.

Thus C.P for 20 orange will be 7/5*20 or 28 Rupees

S.P. for 20 Oranges= 25 Rs

As C.P>S.P , there is a loss

Loss: 28-25= 3

Loss percentage= 3/28 *100

= 7 17/19%

Answer 2

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%
