subtracting 40% of a no. from the no. , we get the result as 30. The no. is

Answer 1

x-(40x/100)=30
60x/100=30
60x=3000
x=3000/60=50.
therefore, the no. is 50

Answer 2

Define x:

Let the number be x

40% of the number = 0.4x

Form equation and solve for x:

x - 0.4x = 30

0.6x = 30

x = 30 ÷ 0.6

x = 50

Answer: The number is 50
