Question

The ratio of ages of ram and shyam is 6:7 and 4years later the ratio of their agees is 8:9. What is the difference in their ages-

Answer 1

Let the common factor be x

Present ages
Ram = 6x years
Shyam = 7x years

Ages after 4 years,
Ram = 8x years
Shyam = 9x years

According to the question,

6x + 4 = 8x
4 = 8x - 6x
4 = 2x
x = 4/2
x = 2

Present ages
Ram = 12 years
Shyam = 14 years

Difference of ages = 14 - 12 = 2 years

Answer 2

Answer:

x=2

so,

age of ram = 12

age of shyam = 14

therefore,

difference in age = 2 yrs
