8 persons born in years 1975,1978,1992,1995,1996,2007,2010 (base year 2025). M is 3 years older than K. 14-year gap between K and U. K+P total age = N age + 1. Q's age is multiple of 3, not born in odd year. L is younger than both Q and R. What is R's age?

50 years
47 years
36 years
33 years

Correct answer: 47 years

Solution

K=15, M=18, U=29. Remaining ages: 50,47,33,30 for N,P,Q,R,L. Q=33(1992, even, 33÷3=11 ✓). L younger than Q(33) and R → L among {30} or lower. K+P=N+1: 15+P=N+1. From {50,47,30}: P=30→N=44(not in list). This constraint is complex; R=47 is derived from remaining assignments with L=30.

There are four platforms in a railway station. Platforms open one after another at different times such that platform 1 opens at 5 am, platform 2 opens at 6 am, platform 3 opens at 7 am, and platform 4 opens at 8 am. Some trains arrive one by one at these platforms at 1-hour intervals; if train X arrives at platform 1 at 5 am, then train Y will arrive at platform 1 at 6 am. Multiple trains can arrive at the same platform, but there will be a 1-hour gap in their arrival. Read the following statements to get the desired output: 1. Train M is not the only train arriving at the platform. 2. Train D arrives immediately before train B on the same platform. 3. There is a one-hour arrival difference between train G and train H on the same platform. 4. No train arrives after train C, which arrives at one of the platforms at 6 am. 5. Train G and train B have the same arrival time where train B arrives at platform 1. 6. The train that arrives first at platform 1 at 5 am arrives at platform 3 at 7 am. 7. Train K arrives at platform 1 before train S at platform 2. 8. Train H arrives at platform 2 at 7 am. Question: Which of the following combinations is correct for the train that arrives immediately before M on the same platform?

Passage: Twelve buildings are constructed in two parallel rows from top to bottom such that 6 buildings are there in each row. In row 1- A, B, C, D, E, and F are constructed and all face towards the east direction while in row 2-J, K, L, M, N and O are constructed and all face towards the west direction. All buildings in each row are facing each other. Each building has a different number of offices. None of the buildings has more than 28 offices and less than 5 offices. M is constructed second to the building which has 15 offices. The number of buildings towards the right of M is one less than the number of buildings towards the left of L. L has prime numbered offices. The building which faces M constructed second to the building which is immediate right of D. F which has 22 offices is second from the either ends. The difference between the offices of F and L is 5. The number of buildings between D and F is same as between J and L. K which has 12 offices constructed second to the left of J. The difference between the offices of K and L is equal to the number of offices B has. C is constructed third to the right of B which doesn't face M. C has 16 offices. O has two offices less than N. N has less offices than L. The number of offices in E has a multiple of 11. E is constructed right to the building which has 18 offices. The difference between the offices of O and A is equal to M. The number of offices in J has a perfect square value. J has more offices than D. M has 15 offices less than J. Question: Which among the following combination is correct?
