Fifteen packing containers of three sizes and 5 colours

Logical Reasoning Aptitude Check (Moscow)(1986) (Krasnogorsk Native College students Meet)

There are 15 packing containers of three completely different sizes – giant, small and medium and are of 5 completely different colours – crimson, white, black, yellow and orange. They’re organized in keeping with some rule from 1–15 (i.e., 1 being the field on the excessive left and 15 being the field on the excessive proper). Pink packing containers will not be at prime locations and in addition not on the place that’s dice of a pure quantity. Each medium sized field has one small field and one giant field adjoining to it on its both aspect. No two packing containers of the identical measurement are stored collectively.

There are 5 packing containers of every measurement. Every measurement has all of the 5 coloured packing containers. Black and white packing containers will not be collectively. Additionally crimson and orange packing containers are at all times collectively. The primary field is a big white field and the final field is a small black field. A small field just isn’t the one field in between two medium packing containers and it’s by no means stored to the quick proper aspect of the big field. As you proceed with the questions, you could use knowledge from the earlier query/s to reply the later ones.

1. The crimson medium field is at:

   • (a) twelfth place
   • (b) eighth place
   • (c) 14th place
   • (d) Can’t be decided

2. If the white field is on the third place from the left finish, which field is on the seventh place from the left finish?

   • (a) Black small field
   • (b) Black giant field
   • (c) Yellow giant field
   • (d) Can’t be decided

3. If the orange field is on the eleventh place from the left finish and no three packing containers of the identical coloration besides white packing containers are positioned collectively, then from the left finish the crimson field could be positioned at place:
   (a) 4 (b) 12 (c) 10 (d) 6

   • (i) Each (a) and (b);
   • (ii) Each (b) and (c);
   • (iii) Each (a), (c) and (d);
   • (iv) Each (c) and (d)

4. If the numerical positions of the locations at which yellow packing containers are stored are added collectively, then what’s the whole?

   • a) 18
   • b) 14
   • c) 21
   • d) Can’t be decided

Utilizing some logical deductions by means of the given situations, I discovered three such potentialities:

Right here, L denotes giant, M denotes medium, S denotes small, R denotes Pink, B denotes Black, Y denotes Yellow, O denotes Orange, W denotes White.

• From the tables we see that (c) will the right choice in Q1).

• From the first two tables we see that within the seventh place from the left we will both have a big black field or a big white field, so we won’t uniquely decide the field within the seventh place so the choice (d) appears appropriate for Q2).

• From the first desk we see that (ii) is the right choice for Q3).

• If we add the numerical positions of yellow packing containers within the 1st and third desk, we see that we don’t get the identical end result so the reply for This fall) will likely be choice (d).

Am I appropriate in my logical deductions? Please share your ideas.
