Ravi 's age is three times that of Gaurav 's. After 18 years Ravi will be twice as old as Gaurav . What are their present ages?

They both aren't born yet. Ravi is -54 years old, and Gaurav is -18 years old.

Step-by-step explanation:

r=3g

r+18=2g

Substitute 3g for r

3g+18=2g

18=-1g

-18=g

r=(-18)*3=-54

This one strikes me as an odd one, but my working is correct, you can see that for yourself. Hope this helps and please tell me if this was the correct answer.

the answer is two. hope this !

47 - 90 = 43

43 - 180 = x

x = 137
