Let the Number be x
when x is decreased by 10%, it becomes 108

=> x - 10% of x = 108
=> x - (10/100)×x = 108
=> x(1 - 10/100) = 108
=> x(90/100) = 108
=> 90x = 108×100
=> x = 120

Therefore,
Number is 120

120 + y% of 120 = 144
=> y% of 120 = 144-120
=> (y/100)×120 = 24
=> y/10 = 2
=> y = 20%

Therefore,
the number 120 when increased by 20% gives 144
