Q. Present age of S is 45 years, while present age of P is 33.33% more than that of Q. Ratio of age of R after 5 years to that of S after 5 years is 2:5 years respectively. Q is 3 years older than R. M = Find the present average age of S after 5 years and Q together.
N = T is 3 years older than U, while the present age of Q is 40% less than that of U. Find the present age of T.
L = Find average age of P, Q, R, and S together after 9 years.
A.M > N > L
B.M < N > L
C.M > N = L
D.M = N < L
E.M > N < L
Ans:M > N < L
Sol:
Present age of S = 45 years Age of S after 5 years = 45 + 5 = 50 years So, age of R after 5 years = 50 x 2/5 = 20 years Present age of R = 20 – 5 = 15 years Age of Q = 15 + 3 = 18 years For M Average age of S after 5 years and Q together = (50 + 18)/2 = 34 years For N Age of U = 18/60 x 100 = 30 years Age of T = 30 + 3 = 33 Years For L Average age of P, Q, R, and S after 9 years = (24 + 15 + 18 + 45 + 36)/4 = 34.5 years So, M > N < L Hence the answer is option E
