Answer 2

Answer:

The ratio of Ages after 8 years is 6 : 5.

Step-by-step explanation:

Given :

Ratio of ages = 4 : 3

Their sum of Ages = 28

To Find :

Ratio of Ages after 8 years

Solution :

Let the present Ages be -

• Vishnu as 4x
• Jyothi as 3x

➠ 4x + 3x = 28

➠ 7x = 28

➠ x = 28/7

➠ x = 4

$\rule{300}{1.5}$

Vishnu's present age =

➠ 4 × 4

➠ 16

Vishnu = 16 years old

$\rule{300}{1.5}$

Jyothi's present age =

➠ 3 × 4

➠ 12

Jyothi = 12 years old

$\rule{300}{1.5}$

Ages after 8 years =

➠ Vishnu = 16 + 8 = 24 years

➠ Jyothi = 12 + 8 = 20 years

$\rule{300}{1.5}$

Ratio of their Ages =

➠ Vishnu/Jyothi

➠ 24/20

➠ 6/5

➠ 6 : 5

$\therefore$ The ratio of Ages after 8 years is 6 : 5.
