Question

Fifteen years from now Ravi's age will be four times his present age. What is Ravi's present age?

Answer 1

Step-by-step explanation:

Let present age be x

then 15 years from now ravis abe will 4 times the present =

                                            (x+15) = 4x

                                             15 = 4x - x

                                             15 = 3x

                                             15/3 = x

                                             5 = x

thus present age of ravi is 5 years

Answer 2

Let Ravi's Present age be x
His age after 15 years will be (x+15)

Ravis age will 4 times

4x = x+15
3x=15
x=15÷5
so,x=5

Ravis present age is 5 years and his age after 15 years will be 20...
