Correct question : If 40% of 50 = x% of 80 , what is the value of x ? (A) 20 (B) 25 (C) 30 (D) 40

Given :

40% of 50 = x% of 80

To find :

The value of x is

(A) 20

(B) 25

(C) 30

(D) 40

Solution :

Step 1 of 2 :

Write down the given equation

Here the given equation is

40% of 50 = x% of 80

Step 2 of 2 :

Find the value of x

40% of 50 = x% of 80

$\displaystyle \sf{ \implies }50 \times \frac{40}{100} = 80 \times \frac{x}{100}$

$\displaystyle \sf{ \implies } \frac{40}{2} = \frac{80x}{100}$

$\displaystyle \sf{ \implies } \frac{80x}{100} = 20$

$\displaystyle \sf{ \implies }x = 20 \times \frac{100}{80}$

$\displaystyle \sf{ \implies }x = \frac{100}{4}$

$\displaystyle \sf{ \implies }x = 25$

So required value of x = 25

Hence the correct is (B) 25
