Question

Ans:​

Answer 1

THE GRAND ANSWER :

Panna's age now = x

Panna's age 4 years back = x - 4

Panna's age after 8 years = x + 8

Now, Panna's age after 8 years is three times her age 4 years back

Therefore,

Panna's age after 8 years = 3 × (Age 4 years back)

x + 8 = 3 × (x - 4)

x + 8 = 3x - 12

8 + 12 = 3x - x

20 = 2x

x = 10

So, Panna's present age is 10 years

Answer 2

Answer:

x = 10

Step-by-step explanation:

Let the present age of Panna be x years.

4 years ago:

Her age was x-4 years.

After 8 years:

Her age will be x+8 years.

Panna's age after 8 years is three times her age 4 years back.

x+8 is three times of x-4

x+8 = 3(x-4)

x+8 = 3x-12

3x-x = 12+8

2x=20

x=20/2

x=10.

Hence, Panna's age is 10 years.
