Question

The ratio of present age of  Manish and Kamal is 3 : 5 and the sum of their age is 80 years. Then what will be the ratio of ages of Kamal and Manish respectively after 10 years ?
​

Answer 1

Answer:

2:3

Step-by-step explanation:

Manish:Kamal

3x+5x= 80

8x= 80

x=80/8

x= 10

Manish= 3x= 30×10

Kamal= 5x= 50×10

AFTER 10 YEARS MANISH:KAMAL= 40:60

Manish:Kamal= 2:3

Answer 2

Ratio of age of Manish and Kamal = 3:5

Sum of their ages = 80

Ratio of age of Manish and Kamal = 3x : 5x

According to the question

$3x + 5x = 80 \\ </p><p>8x=80 \\ </p><p>⇒x= \frac{80}{8} \\ </p><p>⇒x=10$

Present age of Vimal = 3 x 10 = 30 years

Present age of Aruna = 5 x 10 = 50 years

10 years after age of Manish = 30 + 10 = 40 years

10 years after age of Kamal = 50 + 10 = 60 years

Ratio of age of Manish and Kamal after 10 years = 40:60=2:3
