Question

the ratio between the prices of a scooter and and a refrigerator is 4:1 . if the scooter costs Rs.4500 more than the refrigerator, find the price of of the refrigerator

Answer 1

Let the price of scooter be Rs. 4x and the refrigerator be Rs. 1x (or x)

By condition,
4500+x = 4x
=> 4500 = 4x-x
=> 3x = 4500
=> x = 1500

So, the price of the refrigerator = Rs. x = Rs. 1500

Answer 2

First of all, let the common ratio be x.

Then, the prices of scooter and refrigerator will be - 4x and 1x (or x) respectively.

By condition,
4x = 4500 +x

=> 3x = 4500

=> x = 1500

$\boxed{YOUR\:\:ANSWER\:\:IS\:\:RS. \:\:1500}$
