Answer 1

Step-by-step explanation:

Your question: The sum of the ages of Sejal and Sonal is 30 years. Sejal is elder to Sonal by 2 years. Then find the age of Sejal.

Your answer:

Let the age of Sonal be 'x' years

So, the age of Sejal is '2x'

Given, Their sum of ages = 30

Therefore, according to the question:

the question: $2x + x = 30$

the question: $2x + x = 30$[ adding 2x and x ]

$3x = 30$

[ now, let's divide 30 by 3]

$x = \frac{30}{3}$

[tex]x = 10[/tex]

Therefore, the age of Sejal is 2x = 2*10 = 20 years

Answer 2

Step-by-step explanation:

Sejal age = x

Sonal age = x + 2

x + (x+2) = 20

2x + 2 = 20

2x = 20 - 2

2x = 18

x = 18/2

x = 9

Therefore,

Sonal age = x = 9

Sejal age = x+2 = 9+2

= 11

9+11

20
