Question

If two-third of a number is 30 less than the original number the number is

Answer 1

Answer:

The number is 90.

Step-by-step explanation:

Step 1:

Let the number be x

Step 2:

2/3 of x =( x-30) [product of two third of a given number equal to the subtract the value of x and 30]

Step 3: To find the value of x

(2x)=(3x-90)

2x-3x=-90

Step 4:

-x=-90(both the sides same sign, so neglecting sign on both left hand sides and right hand side)

x=90  

Answer 2

Answer:

2/3 of x = x - 30

2/3 × x = x - 30

2x = 3(x - 30)

2x = 3x - 90

2x - 3x = -90

-x = -90

x = 90
