Currently, the ratio of their ages is 5: 3. Suppose, their ages are: 5x and 3x.

Sara’s age 4 years ago = 5x – 4

Vaishali’s age after 4 years = 3x + 4

Ratio of Sara’s age 4 years ago and Vaishali's age after 4 years is 1 : 1

Therefore,

(5x - 4) / (3x + 4) = 1/1

Solving, we get x = 4

We are required to find the ratio between Sara’s age 4 years hence and Vaishali’s age 4 years ago.

Sara's age: (5x + 4)

Vaishali's age: (3x – 4)

Putting the value of x, we get:

(5x + 4) / (3x - 4) = 3/1 = 3:1

Answer:

hiiiiii

your answer is here !

Step-by-step explanation:

Currently =>

the ratio of their ages is 5: 3.

Suppose,

their ages are =>

5x and 3x.

Sara’s age 4 years ago = 5x – 4

Vaishali’s age after 4 years = 3x + 4

Ratio of Sara’s age 4 years ago

and

Vaishali's age after 4 years is 1 : 1

Therefore,

(5x - 4) / (3x + 4) = 1/1

Solving,

we get x = 4

We are required to find the ratio between Sara’s age 4 years hence and Vaishali’s age 4 years ago.

✓ Sara's age => (5x + 4)

✓ Vaishali's age => (3x – 4)

✓ Putting the value of x, we get =>

(5x + 4) / (3x - 4) = 3/1 = 3:1

follow me.
