Question

Buy selling 36 apples a vendor loses selling price of 4 apples.Find his loss percent.

Answer 1

Let the sp be x
Sp of 8 aaples=rs.36x
Sp of 4 aaples=rs.4x
Lost amount==sp of 4 apples=4x

Cp of 36 apples=sp+loss
=36x+4x
=40x

Loss%=loss/cp×100
=4x/40x×100
=10%

Answer 2

Answer: There is 10% loss for the vendor when he sells 36 apples.

Solution:

Let the selling price be denoted as SP and cost price as CP

Let the cost price of 36 apples be 36CP

Given by selling 36 apples, the seller lost the price of 4 apples.

Hence the cost price of 36 apples = 36 SP + 4 SP = 40SP

Loss % $\begin{array}{l} { =\frac { { Los }s }{ { CP } } \times 100 } \\ \\ { =\frac { 4{ x } }{ 40{ x } } \times 100 } \end{array}$

            = 10 %

The loss in % is 10.
