a= 16.7-22.2/5
a= -5.5/5

Answer:
Present age of Ramesh=20
Present age of Mahesh=28
Step-by-step explanation:
Let the present age of remesh be 5x and
Age of present Mahesh be 7x
After four years, age of Remesh=5x+4
Age of Mahesh=7x+4
According to the question,
5x+4/7x+4=3/4
By cross multiplication,
20x+16=21x+12
x=4
=>Age of Ramesh=5x=20
Age of mahesh=7x=28
