Question

The cost of a train ticket from New Delhi to Dehradun has risen by 20% to Rs. 600. What was the original price of the ticket?​

Answer 1

Answer:

Original Price was Rs. 500.

Step-by-step explanation:

Let the original price be Rs. x.

∴ Increase in Price = 20% of Rs. x

                                = 20/100 of x

                                = Rs. x/5

∴ Increase Price = Original Price + Increase in Price

                            = x + x/5

                            = 6x/5

Given,

New cost of the ticket = Rs. 600

∴ 6x/5 = 600

⇒ x = 600 × 5/6

⇒ x = 500

So, Original Price was Rs. 500.

Answer 2

$\huge\red{Answer}$

If original price was X then

New price = X+ 20% of X = X+0.2X = 1.2 X

But given New price = Rs 600

Therefore 1.2X = 600

⇒X= 600/1.2 = 500

Therefore Original Price of ticket was Rs 500
