Question

John sold an article to Peter at 20% profit and
Peter sold it to Mohan at 5% loss. If Mohan
paid 912 for the article; find how much did John pay for it?​

Answer 1

Step-by-step explanation:

Let

Cp=₹100

Sp on which Peter buy it =₹120 (sold at 20% profit)

Now Peter sold it on 5% loss

Sp=cpx(100-loss%)/100

Sp=120x(100-5)/100

Sp=120x95/100

Sp=120x19/20

Sp=6x19

Sp=₹114

But according to question mohan pay ₹912 for it

So

One unit assumed =912/114

=8

So initial cp was =100x8=₹800

John pay ₹800 for it
