Question

The sum of Shikha and Ravi's present age is 20. Five years from now, Shikha's age will be twice of Ravi's age. Find their present age.​

Answer 1

Let Hema's present age be x years.

After 20 years,her age will be (x+20) year.

according to the question ,

2x = x + 20

2x - x = 20

x = 20

x= 20

Hence,Hema's present age is 20 years.

Answer 2

Step-by-step explanation:

Let the present age of Shikha be x years.

Therefore,

the present age of Shikha’s brother Ravish

= (x + 3) years.

So,

sum of their ages = x + (x+ 3)

⇒ x +(x + 3) = 37

⇒ 2x + 3 = 37

Subtracting 3 from both sides,

we get

⇒ 2x+ 3 – 3 = 37 – 3

⇒ 2x = 34

Dividing both sides by 2,

we get

⇒ 2x/2 = 34/2

⇒ x = 17

Therefore, the present age of Shikha = 17 years, And the present age of Ravish = x + 3 = 17 + 3 = 20 year
