Question

On increasing a number by 22%
it becomes 610. Find the number.​

Answer 1

Answer:

     x = 500

Step-by-step explanation:

let the number be 'x'

22x / 100 + x = 610

22x + 100x / 100 = 610

22x + 100x = 61000

122x = 61000

x = 61000 / 122

x = 500

Answer 2

Answer:

x = 500

Step-by-step explanation:

let the number be x.

According to question,

x + 22% of x = 610

⇒ x + 22x / 100 = 610

⇒ (100x + 22x) / 100 = 610   -[taking LCM and making the denominators same]

⇒ 122x / 100 = 610

⇒ x = 610 * 100 / 122 = 500 .
