Study the following information carefully and answer the question given below. Eight persons J, L, F, B, C, O, S and W sit in a row, not necessarily in the same order, such that some of them face north and some face south. Not more than two persons sit adjacent to each other facing the same direction. The number of persons sitting between F and C is a multiple of 3. O sits 5th to the left of C, who faces north. B and L sit immediate left of each other and neither of them sits adjacent to O and C. An equal number of persons sit to the left of both B and W. O and S sit adjacent to each other and both face the same direction. O does not sit at any of the extreme ends. Who among the following pairs do not face the same direction?

1. W, C
2. J, B
3. O, B
4. F, O

Correct answer: F, O

Solution

Using the positional clues, the complete arrangement can be derived uniquely. Once the directions are assigned consistently with the restriction on adjacent same-facing persons, F and O are found to face opposite directions, while the other listed pairs do not satisfy the condition.

• Directions: Study the information carefully and answer the question given below. Six persons stay at different steps of a stair of 40 steps, facing the 40th step. P stays at a step that is a multiple of 9 but above the 20th step. The number of steps ahead of P is the same as the number of steps behind S. There are seven steps between S and Q, and Q is not at an even-numbered position. The number of steps between Q and S is half the number of steps between T and R. The number of steps between R and U is one more than the number of steps behind S. U stays below the 25th step. Both T and U stay somewhere between P and Q. T stays at a step that is a multiple of 7 but above the 15th step. Now, all the persons play a Ludo game and move according to the given conditions: 1. If the dice throw is more than 5, the person moves 13 positions behind from the actual position; if not possible, then moves 4 steps ahead. 2. If the dice throw is 3, the person moves to the step that is a multiple of 19 but above the one who threw the dice first. 3. If the dice throw is less than 3, the person moves 7 positions ahead of the actual position. 4. If the dice throw is 4, the person moves to the step just below the 2nd person who threw the dice. Throws: 1. T throws and gets 6 2. U throws and gets 3 3. R throws and gets 2 4. Q throws and gets 4 Question: What is the sum of the number of steps of R and T after the rearrangement?
