Let the number = x
Third part of the number = x / 3
Fifth part of the number = x / 5
Given relation between these to
terms are ,
x / 3 - x / 5 = 4
Find the LCM of 3 and 5 = 3 ? 5 = 15
( 5x - 3x )/ 15 = 4
2x / 15 = 4
x = (4 / 1 ) ? ( 15/ 2 )
After cancellation
x = 2 ? 15
x = 30
Therefore,
Required number = x = 30
Hope this will helps you.
