Question

Arun’s grand mother is ten times older than him. Grand mother is 54 years older than Arun. Find their present ages.​

Answer 1

Answer:

age of arun is assumed to be x years

then age of arun's grandmother is 10x

Also age of grandmother=x+54

on equating 2 and 3 we get

10x= x+54

9x=54

x=6

age of arun=6 years

age of grandmother=10×6=60

Answer 2

Step-by-step explanation:

Let the present age of Arun is x years.

So, the present age of grandmother is 10x years.

According to the given condition, we have

10x - x =54

➡9x= 54

➡ x = 6 ... on dividing 9 from both the sides

Hence , the present age of arun is 6 year and the Grandmother age is 60 years.
