Question

six year ago kirti age was 1/4of her parents age what will be her age after 7 years​

Answer 1

Answer:

Kirti present age will be 15 years after 7 years

Step-by-step explanation:

Lets assume "x" years as Kirti's present age.

So,

Age 6 years ago will be "x - 6" years

According to the question, we can write the equation as

x - 6 = \frac{1}{4} xx−6=

1

x

⇒ 4(x - 6) = x4(x−6)=x

⇒ 4x - 24 = x4x−24=x

⇒ 4x - x = 244x−x=24

⇒ 3x = 243x=24

⇒ x = \frac{24}{3}x=

3

24

⇒ x =x= 8 years ← present age of Kirti

Now,

Age after 7 years will be "x + 7" years

∴ Kirti's present age after 7 years = 8 + 7 = 15 years

Thus, Kirti present age will be 15 years after 7 years.
