Question

Answer the given questions.

1. The ratio of present age of Ramesh and Mahesh is 5 : 7. After four years the ratio of

their age will be 3 : 4. Find out their present age.​

Answer 1

Step-by-step explanation:

The present age of Ramesh is 20 years

The present age of Mahesh is 28 years

Step-by-step explanation:

Let,

The present age of Ramesh = 5x

The present age of Mahesh = 7x

After four years,

The age of Ramesh = 5x + 4

The age of Mahesh = 7x + 4

And

The ratio of thier age will be 3 : 4

So,

⇒

⇒ 4 (5x +4) = 3 (7x + 4)

⇒ 20x + 16 = 21x + 12

⇒ 20x - 21x = 12 - 16

⇒ -1x = - 4

⇒ 1x = 4

⇒ x = 4

★ Value of 5x :

⇒ 5 (4)

⇒ 5 × 4

⇒ 20

★ Value of 7x:

⇒ 7 (4)

⇒ 7 × 4

⇒ 28

Therefore,

The present age of Ramesh is 20 years

The present age of Mahesh is 28 years

Answer 2

Answer:

RAMESH AGE 20 yrs and MAHESH AGE 28yrs present age of ramesh be 5x and mahesh 7x .

5X+4

7X+4

RATIO IS 3:4

4(5X+4)=3(7x+4)

20x+4=21x+4

-1x=-4

x=4

5×4=20
