Answer:
Let the present ages of Sreelata, Pinki and Ronit be S, P and R, respectively.
S = 2P/7 …(1)
P-7 = 5R …(2)
R+18 = 25 …(3)
From (3), R = 25–18 = 7 years.
From (2), P = 5R+7 = 5*7 + 7 = 35 + 7 = 42 years.
From (1), S = 2P/7 = 2*42/7 = 12 years.
At present, Sreelata is 12 years, Pinky is 42 years and Ronit is 7 years. Answer
