Question
Meena is eight years older than Sita. Eight years ago,
three times the age of Sita is 15 more than the age of Meena. Find the present age of Sita.Solution
ATQ,
Let the present age of Sita be βSβ years.
Present age of Meena = (S + 8) years
ATQ,
3 Γ (S - 8) = (S + 8) - 15
Or, 3S - 24 = S - 7
Or, 2S = 17
Or, βSβ = 8.5
So, present age of Sita = 8.5 years
