Question

A trademan gains 20% at the selling price. if cost is increased by 12% and the selling price is increased by 8% , then find the revised profit​

Answer 1

Answer:

Solution:

Let the cost price of the article =x

Given tradesman sold an article at a loss of 20%

i.e., (

100

100−20

)x=0.8x

If the price is increased by Rs.100

then selling price becomes =(0.8x+100)

He gains 5% with selling price =0.8x+100

Profit =SP−C.P=(0.8x+100)−x

=0.2x+100=

100

5

of C.P

⇒ −0.2x+100=0.05x

⇒ 0.25x=100

⇒ x=400
