Directions: A number arrangement machine, when given an input line of numbers, rearranges them following a particular rule in each step. The following is an illustration of input and rearrangement. Input: 35 47 59 39 68 Step I: 332 443 554 336 662 Step II: 331 441 551 333 664 Step III: 331 333 441 551 664 Step IV: 7 9 9 11 16 And Step V is the last step of the arrangement. As per the above rule followed in the above steps, find out in each of the following questions the appropriate step for the given input: Input: 19 27 78 48 57 What is the sum of the numbers which is 3rd from the left in Step III and 4th from the right in the final step?
- 447
- 454
- 443
- 466
Correct answer: 454
Solution
The machine first transforms each number according to a digit-based rule, then rearranges them in ascending order, and finally converts them to another form in Step IV/V. For the given input, the 3rd number from the left in Step III and the 4th from the right in the final step add up to 454.

- 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?
