Question

if 11% of a number is exceeds 7% is18

Answer 1

Hi ,

let the number = x 

11 % of the number = 11x / 100

7 % of the the number = 7x/ 100

According to the problem,

11% of a number is exceeds 7% is 18

write the above statement into equation form

11x /100 - 7x / 100 = 18

⇒ (11x - 7x ) /100 = 18

⇒ 4x / 100 = 18

⇒ x = (18 /1 ) × ( 100 / 4 ) 

after cancellation,

x = 450 

∴∴ Required number = x = 450

I hope this will helps you.
