Question

If ramu is 6 times as old as shamu and shamu is half of age of Dhruv.Sum of their ages is 108 ...this was scenerio of 2011 .find their ages in year 2031.

Answer 1

Answer:

Step-by-step explanation:

Let ramu's age be x , shamu's be y and dhruv's be z

According to the question,

Ramu's age, x= 6y

Shamu's age, y= z/2

So Dhruv's age z= 2y  (Shamu's age is 1/2 of dhruv's age. So dhruv's age is 2             times shamu's age)

x+y+z=108

6y+y+2y=108

9y=108

y=108/9=12

So, y=12

     x=6y=6*12=72

     z=2y=2*12=24

So, Ramu is  72 years old

     Shamu is 12 years old

     Dhruv is 24 years old

 These are the ages in 2011.

In 2031, Ramu's age= 72+20=92

             Shamu's age= 12+20=32

             Dhruv's age= 24+20=44
