Question

a number exceeded 40% of it self by 120. What will be 45% of that number?​

Answer 1

Answer:

Let the number be x

x - 40% of x = 120

or, 60x/100 = 120

or, 3x/5 = 120

or, 3x = 120 x 5

or, 3x = 600

or, x = 600/3

or, x = 200

45% of x = 45% of 200

= 45/100 x 200

= 45/1 x 2

= 90

Therefore, 45% of that number is 90.
