Question

by selling a 100 mangoes,a fruit seller gains the s.p of a mangoes.find the gain%​

Answer 1

Answer:

Now let us consider our question. Let us take the selling price (S.P) of each mango = Rs. x.

So, we get the selling price (S.P) of 20 mangoes = Rs. 20x.

Also, we get the selling price (S.P) of 100 mangoes = Rs. 100x.

We are given that by selling 100 mangoes, fruit seller gains S.P of 20 mangoes, so we get,

Gain on selling 100 mangoes = S.P of 20 mangoes.

By substituting the value of S.P of 20 mangoes = 20x, we get, Gain on selling 100 mangoes = Rs. 20x.

Now, we know that Gain = S.P – C.P. So, we get (S.P of 100 mangoes) – (C.P of 100 mangoes) = 20x.

By substituting the value of S.P of 100 mangoes = 100x, we get, 100x – (C.P of 100 mangoes) = 20x.

So, we get 100x – (C.P of 100 mangoes) = 20x.

So, we get, (C.P of 100 mangoes) = 100 – 20x = Rs. 80x.

So, for 100 mangoes, we get,

C.P = 80x

S.P = 100x

Gain = 20x

Now, we know that,

Gain % =GainC.P×100

.

By substituting the value of Gain and C.P, we get,

Gain % =20x80x×100

=14×100

= 25 %

So, we get the gain % on selling 100 mangoes as 25 %.
