Question

what number is that from which if you subtract 40 the difference will be one third of the original number​

Answer 1

Answer:48

Step-by-step explanation:

Let the number be ‘x'

48 subtracted from it x-48

Reduced to its one third = (1/3)x

x-48= (1/3)*x (equation)

Solving

x-1*x/3=48

(3x-x) ÷3= 48

2x/3 = 48

2x= 48*3

x= 48*3/2=24*3= 72

Two third of the number = 72*(2/3) = 24*2=48

Ans:48

Answer 2

Answer:

60

Step-by-step explanation:

let the number be X

x-40=X/3

x-x/3-40=0

3x-x-120/3=0

2x-120=0

2x=120

X=60
