Question

Find the value of x if

Answer 1

Answer:

a) 270

b) 800

c) 400

Step-by-step explanation:

a) 10% of x is 27

 => (10/100)*x = 27

 => x = (27 * 100) /10

 => x = 270

b) 1% of x is 8

 => (1/100)*x = 8

 => x = 8*100

 =>x = 800

c) 45% of x is 180

 => (45/100) * x = 180

 => x = 180*(100/45)

 => x = 4*100

 => x = 400
