Question

A dealer of scientific instruments allows 20% discount on the marked price of the instruments and still makes a profit of 25% . If his gain over the sale of instrument is ₹150 , find the marked price of instruments . [Please show the steps]

Answer 1

Answer:

d%=20, p%= 25 , p=150

let mp=x

p%=p/cp. ×100

20= 150/cp. ×100

cp=150/20×100

cp=750

now find sp= (100+ p%)/100. ×cp

then find mp=100/(100-d%). ×sp

I think that you can get answer thanks

Answer 2

Answer:

Let P be the cost price

The dealer makes a profit of 25%

So by the given condition

P × 25/100 = 150

P = 600

So the selling price = 600 + 150 = ₹ 750

Let M be the market price

So by the given condition

M × 80/100 = 750

M = 750× 100/80 = 937.50

So the market price = ₹ 937.50
