Question

if a number is 20% more than 50. Find the number ​

Answer 1

Answer:

$60$

Step-by-step explanation:

20% OF 50 = $\frac{20}{100}$×$50$

20% OF 50 = $10$

10 MORE THAN 50 = 50+10 = 60

ANSWER IS 60

Answer 2

If a number is 20% more than 50.

GIVEN

Let the unknown number be x

x = 20%x + 50TO

FIND :- The number

SOLUTION :-

According to the question the number is more than 50 by 20% of that number

.So the equation is :-

$20\%x + 50 = x \\ \\ \\ \implies \frac{20x}{100} + 50 = x \\ \\ \\ \implies 50 = x - \frac{20x}{100} \\ \\ \\ \implies 50 = x - \frac{x}{5} \\ \\ \\ \implies \frac{5x - x}{5} = 50 \\ \\ \\ \implies 4x = 250 \\ \\ \\ \implies \boxed{x = \frac{250}{4} = 62.5}$

The Unknown Number is 62.5

VERIFICATION :-

20%x + 50 = x

LHS

= 20/100 × 62.5 + 50

= 1/5 × 62.5 + 50= 12.5 + 50

= 62.5

= RHS

HENCE OUR ANSWER IS CORRECT
