Condition based number series
Directions (1-2):Â There are two rows given and to find out the resultant of a particular row we need to follow the following steps: –
Step 1:Â If an odd number is followed by an even number (but not a cube number) then the resultant comes by multiplying the numbers.
Step 2:Â If an odd number is followed by a cube number then the resultant will be the difference of the cube number and the odd number.
Step 3:Â If an odd number is followed by another odd number (but not a cube or square) then the resultant will be the addition of both the numbers.
Step 4:Â If an even number is followed by an odd (non-prime) number then the resultant will be the difference between the odd number and the even number.
Step 5:Â If an even number is followed by an odd (prime) number then the resultant will be the division of the higher number by a lower number.

Answers :
Directions (1-2) :
1) Answer: B
80Â Â 9Â Â 37=>80-9=>71 (by step 4)
71+37=>108 (by step3)
78Â Â 13Â Â 15=>78/13=>6 (by step 5)
15-6=>9 (by step 4)
108*9=972
Hence b is the correct answer.
2) Answer: B
17Â 512Â 13=>512-17=>495 (by step 2)
495+13=>508 (by step 3)
508-3Â Â Â Â Â Â Â 2(508)-50% of 9(508)+132-20 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 729
505Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 1419Â Â Â Â Â Â Â Â Â Â Â Â Â Â 729=>505+1419=>1924(by step 3)
1924Â Â 729=>1924-729=>1195 (by step 2)
Hence b is the correct answer.
Directions (3-6):
The total number of rooms on floor number 3 is twicethe number of rooms inflat A of floor number 1. The flat in which the area of each room is 576 ft is to the west of the flat in which the area of each room is 192 ft. The flat in which the area of each room is 196ft is above the flat which has 5 rooms with the same flat type.
1728/576=3 rooms
1728/192=9 rooms
There is no flat to the east of the flat in which the area of each room is 216 ft. The flat in which the area of each room is 432 ft is above the flat in which the area of each room is 288 ft. Number of rooms in flat B offloor 2 is equal to the sum of the roomsin flat A of floors 1 and 2.
1728/216=8 rooms
1728/432=4 rooms
1728/288=6 rooms
Case 2 and 3 will be dropped because number of rooms in flat B of floor 2 is equal to the sum of the rooms in flat A of floors 1 and 2.
3) Answer: D
Clearly, Total number of rooms on floor 1 = 6+5=11
Hence d is the correct answer.
4) Answer: D
Clearly, Area of each room in flat B of floor number 1 =1728/5= 345.6 ft.
Hence d is the correct answer.
5) Answer: B
Clearly, The room’s area of flat A of floor 3 = 432 ft.
Number of rooms present to the east of the flat in which the room’s area is 432 ft=8
Hence b is the correct answer.
6) Answer: E
Number of rooms in the flat that is just below the flat A of floor number 3is 3
Directions (7-10):
The one who likes red sits third to the right of F. Two persons sit between the one who likes red and the one who likes silver.
The one who likes Green sits second to the left of G. The one who likes white sits on the immediate right of the one who likes Grey. The one who likes Grey faces south. As many persons sits to the right of the one who likes red is same as the right of the one who likes white.
Case3 will be dropped because the one who likes Green sits second to the left of G.
Case 1A will be dropped becauseas many persons sits to the right of the one who likes red is same as the right of the one who likes white.
The one who likes Pink sits second to the left of the one who likes Yellow, who face north. Immediate neighbours of F face theopposite direction. Persons who sit at end face opposite direction to each other.
Case 2 & case 2A will be dropped because the one who likes Pink sits second to the left of the one who likes Yellow, who faces north.
7) Answer: E
Clearly, F who likes silver, sits second to the right of H.
Hence, e is the correct answer.
8) Answer: E
Clearly, No one sits between D and the one who likes Green.
Hence, e is the correct answer.
9) Answer: C
D is third from the left end and Silver is third from the left end.
F is fifth from the right end and Yellow is fifth from the right end.
Similarly, B is first from the left end and Grey is first from the right end.
Hence, c is the correct answer.
10) Answer: E
Silver is second to the right of H, whereas in all other cases the second element is on the immediate right of the first element.
