Answer:
Lalit's age - 7 years, his father's age - 42 years
Step-by-step explanation:
Present age of Lalit = x years
Present age of his father = y years
After 7 years,Lalit's age = x + 7 years
His father's age = y + 7 years = 6x
A/Q ,3( x + 7) = 6x
3x + 21 = 6x
3x = 7 years
Lalit's age = 7 years
His father's age = 6 x 7 = 42 years
