Let, The 1st no. be x
The 2nd no. be y
To Find out:- Ratio of the 1st no. to 2nd no.
According to the question,
30% of x = 1/5 of y
or, 30/100 * x = 1/5 * y
or, 30x/100 = y/5
or, 30x * 5 = y * 100 [ By cross Multiplication]
or, 150x=100y
or, x/y=100/150
or, x/y=2/3
Therefore, x:y=2:3 Ans..
Hence, The Ratio of x:y is 2:3 .
