Answer:

Answer:-

\red{\bigstar}★ Age of Kriti's Father \large\leadsto\boxed{\tt\green{25 \: years}}⇝25years

\red{\bigstar}★ Age of Kriti \large\leadsto\boxed{\tt\green{5 \: years}}⇝5years

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Given:-

Kriti's father's age is 5 times as old as Kriti.

After 5 years father will be three times in as old as Kriti.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• To Find:-

The present ages of Kriti and her father.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Solution:-

Let the age of Kriti's father be 'x' and that of Kriti be 'y'.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Given that,

Kriti's father's age is 5 times as old as Kriti.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore,

➪ \sf x= 5y \dashrightarrow\bf\red{[eqn.i]}x=5y⇢[eqn.i]

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Also,

After 5 years father will be 3 times as old as Kriti.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore,

➪ \sf x+5 = 3(y+5)x+5=3(y+5)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ \sf x+5 = 3y + 15x+5=3y+15

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ \sf x - 3y = 15 - 5x−3y=15−5

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ \sf x - 3y = 10 \dashrightarrow\bf\red{[eqn.ii]}x−3y=10⇢[eqn.ii]

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Substituting eqn.[i] in eqn.[ii]:-

➪ \sf x - 3y = 10x−3y=10

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ \sf (5y) - 3y = 10(5y)−3y=10

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ \sf 5y - 3y = 105y−3y=10

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ \sf 2y = 102y=10

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ \sf y = \dfrac{10}{2}y=210

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★ \large\underline{\underline{\bf\pink{y = 5}}}y=5

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Substituting value of y in eqn.[i]:-

➪ \sf x = 5yx=5y

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ \sf x = 5 \times 5x=5×5

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★ \large\underline{\underline{\bf\pink{x = 25}}}x=25

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, the ages are:-

Father = 25 years

Kriti = 5 years
