Answer 2

Answer:

Step-by-step explanation:

Present age of Ram is 20 years

Present age of Sham is 28 years

Step-by-step explanation:

Let,

Present age of Ram = 5x

Present age of Sham = 7x

★ Four years from now,

The age of Ram = 5x + 4

The age of Sham = 7x + 4

Also,

The ratio of their age will be 3 : 4

So,

⇒$\tt{\dfrac{5x \: + \: 4}{7x \: + \: 4} \: = \: \dfrac{3}{4}}$

7x+45x+4 = 43

⇒ 4 (5x + 4) = 3 (7x + 4)

⇒ 20x + 16 = 21x + 12

⇒ 20x - 21x = 12 - 16

⇒ - 1x = - 4

⇒ x = 4

___________________________

★ Value of 5x :

⇒ 5 (4)

⇒ 20

____________________________

★ Value of 7x :

⇒ 7 (4)

⇒ 28

Therefore,

Present age of Ram is 20 years

Present age of Sham is 28 years
