Answer:
ram is 21years
shyam is 28
Step-by-step explanation:
4years ago the age of Ram = 3(x-4)
4years ago the age of Shyam = 4(x-4)
their sum = 3(x-4)+4(x-4)
42 = 3x-4+4x-4
42 = 3x+4x - 4 - 4
42= 7x - 4 - 4
42 = 7x -8
-7x = -8 - 42
-7x = -50
x =50/-7
x= 7.1
3x = 3*7.1 = 21.3
4x = 4*7.1 = 28.4
the age of Ram = 21 year 3 months
the age of shyam = 28years 4 months
