One third of a number subtracted from 40 is 10. What is the number?

One third of a number subtracted from 40 is 10. What is the number?

Friends…!

Let the number be x

One third of number x is 1/3x or x/3

One third of a number subtracted from 40 is 10. Accordingly:

40 - x /3 = 10

Now solving the equation

(120 - x)/3 = 10

Cross multiplication

120 - x = 10 × 3

120 - x = 30

-x = 30 - 120

x = 90

The number is 90

Answer the number is 90

Now checking the correctness of answer by putting the value of derived number in the equation

40 - x/3 = 10

40 - 90/3 = 10

40 - 30 = 10

10 = 10
