Table of Contents – A Number is Doubled and 9 is Added (Problem Solved)
Important Points to Solve the Problem
- A number is doubled and 9 is added.
- It becomes 75 if resultant is trebled.
The number can be figure out as:
Let suppose the number is y.
Now, number “y” is double and 9 is added
2y + 9
Resultant (2y + 9) is trebled
3(2y + 9) = 75 ________ (i)
Value of y can be find out easily from equation (i) by just simplifying it (y = 8).
Number = ?
Number = y
According to the given condition
3(2y + 9) = 75
2y + 9 = 25
2y = 25 – 9
2y = 16
y = 8
Required Number = 8 answer
