Answer 2

If 20% of a number is 12 , then two third of that number = 40

Given :

20% of a number is 12

To find :

The two third of that number

Solution :

Step 1 of 3 :

Form the equation to find the number

Let the number = n

Now it is given that 20% of the number is 12

By the given condition

$\displaystyle \sf{n \times \frac{20}{100} = 12 }$

Step 2 of 3 :

Find the number

$\displaystyle \sf{n \times \frac{20}{100} = 12 }$

$\displaystyle \sf{ \implies n \times \frac{1}{5} = 12 }$

$\displaystyle \sf{ \implies n = 12 \times 5}$

$\displaystyle \sf{ \implies n = 60}$

Step 3 of 3 :

Find two third of that number

Now two third of the number

$\displaystyle \sf{ = \frac{2}{3} \times 60 }$

$\displaystyle \sf{ = 2 \times 20 }$

$\displaystyle \sf{ = 40}$
