Answer 1

Step-by-step explanation:

Vijay Seema(present)

Diff of age=12yr

4 years ago

Vijay Seema

4x x

Diff=3x=12 (ciz Diff of age ll always be same)

X=4

Vijay Seema(4yr ago)

4×4=16 4×1=4

Present ages of Vijay =16+4=20 Seema=4+4=8

Answer 2

Answer:

⇢ ${\boxed{\bold{Seema= 16}}}$

⇢ ${\boxed{\bold{Vijay = 28}}}$

Step-by-step explanation:

Given:-

⇢ Vijay is older then his sister seema by 12 years. Four year ago, Vijay was four times as old as his sister.

ㅤ

Find:-

⇢ Find their present ages.

ㅤ

Calculations :-

Let x be age of Seema and x + 12 be age of Vijay.

ㅤ

Four years ago:-

⇢ $\rm{Seema = x - 4}$

⇢ $\rm{Vijay = x + 12 - 4 = 8}$

ㅤ

Finding seema's age:-

⇢ $\rm{2(x - 4) = x + 8}$

⇢ $\rm{2x - 8 = x + 8}$

⇢ $\rm{2x - x = 8 + 8}$

⇢ ${\boxed{\bold{x = 16}}}$

ㅤ

Therefore, we know that 16 is the age of seema using seema's age we can find the age present age of Vijay.

ㅤ

⇢ $\rm{x + 12}$

⇢ $\rm{16 + 12}$

⇢ ${\boxed{\bold{28}}}$

ㅤ ㅤ ㅤ ㅤ ㅤ ㅤ

Therefore, 28 is the present age of Vijay.
