Question

number 19, please solve as fast as you can

Answer 1

Let the number be 'x'.

Given that 11% of a number exceeds 7% of the number by 18.

⇒ 11% of x = 18 + 7% of x

⇒ (11x/100) = 18 + (7x/100)

⇒ (4x/100) = 18

⇒ 4x = 1800

⇒ x = 1800/4

⇒ x = 450.

Therefore, the number is 450 - Option (C).

Hope this helps!
