Table of Contents – A Number Whose Fifth Part Increased by 4
Important Points To Solve The Problem
- A number whose fifth part increased by 4.
- Is equal to its fourth part diminished by 10.
The number can be find out in the way.
Let suppose the number is y.
The fifth part of “y” increased by 4
y/5 + 4
Fifth part of y increased by 4 is equal to its fourth part diminished by 10.
y/5 + 4 = y/4 – 10 ________ (i)
Through this equation we can easily figure out the value of y (y = 280).
Number = ?
Solution & Video Solution
Number = y
According to the given condition
y/5 + 4 = y/4 – 10
4(y + 20) = 5(y – 40)
4y + 80 = 5y – 200
80 + 200 = 5y – 4y
y = 280
Required Number = 280 answer
A number whose fifth part increased by 4 is equal to its fourth part diminished by 10, is 280.
