Question

if you subtract 1.2 from a number and multiply the result by 1.2 you get 1.8 what is the number

Answer 1

Let the number be x.

According to question:-
(x-1.2) × 1.2 = 1.8
x-1.2 = 1.8/1.2
x-1.2 = 1.5
x = 1.5-1.2
x = 0.3

Hope it helps.

Sol : Let the number is x.

 When we subtract 1.2 from x then result is ( x - 1.2 ) and by multiplying it by 1.2, we get 1.8.

So,

 ( x - 1.2 ) 1.2 = 1.8

 1.2 x - 1.44 = 1.8

 1.2 x = 1.8 + 1.44

 1.2 x = 3.24

       x = 3.24 / 1.2

       x = 2.7.

So, the answer is 2.7.
