Question

2. An apple were being sold at 50 per kg in the last season. This season they are being sold at 80 per kg. Find the percentage increase in price.​

Answer 1

Answer:

Given, cost price of 1 kg apples =Rs12.50

=> Cost price of 50 kg apples =Rs12.50×50=Rs625

Now, Loss on 50 kg apples % =10 %

=>

C.P.

C.P.−S.P.

×100=10

=>

625

625−S.P.

×100=10

=>625−S.P.=62.5.

=>S.P.=Rs562.5

=>S.P. of 50 kg apples =Rs562.5

Now,

For, Remaining 30 kg apples ,

Cost price of 30 kg apples =Rs12.50×30=Rs375

Let Selling price of 30 kg apples =Rsx

So, Total CP of 80 kg apples =Rs625+Rs375=Rs1000

And Total SP of 80 kg apples =Rs562.5+Rsx

Hence, for required Profit on the whole % =

C.P.

S.P.−C.P.

×100=20

1000

562.5+x−1000

×100=20

=>x−437.5=200

=>x=Rs637.5

Thus, Selling price of 1 kg apple =Rs

30

637.5

=Rs21.25
