Question

ratio of age Ram and Shyam is 10:9 after 8year Ram 28 year. what is present age of Shyam

Answer 1

let the age of ram be 10x and shyam be 9x
after 8 years
ram,
10x + 8 = 28
10x= 20
x= 2
therefore, shyam's age = 9x= 9 x 2 = 18

Answer 2

Let the present age of ram= 10x
And Shyam = 9x
After 8 years
The age of ram = 10 x +8
And Shyam = 9x + 8
According to question
10 x + 8 = 28
10x = 28-8
10x = 20
X = 20/10
X = 2
Then the present age of ram = 10x
=10*2
= 20 years
The present age of Shyam =9 x
= 9*2
=18 years
