Total Questions: 28
Here, in the 1st column, 1st term - (2 x 2nd term) = 3rd term
37 - (5 x 2) = 37 - 10 = 27.
142 - (27 x 2) = 142 - 54 = 88.
87 - (18 x 2) = 87 - 36 = 51.
Hence, "51" is the correct answer.
For row: -
4 x 4 = 16 x 4 = 64 - 1 = 63
8 x 6 = 48 x 6 = 288 - 1 = 287
7 x 5 = 35 x 5 = 175 - 1 = 174
Hence, "174" is the correct answer.
(1st term + 2nd term) = (Total number) ² = 3rd number
7 + 5 = 12, (12) ^ 2 = 144
9+4=13, (13) ^ 2 = 169
Similarly, 8+6=14, (14) ^ 2 = 196
Hence, "196" is the correct answer.
(1st term * 3) + 1 = (2nd term * 3) + 1 = 3rd term
(8 × 3) + 1 = 25, (25 × 3) + 1 = 76
(5 × 3) + 1 = 16, (16 × 3) + 1 = 49
Similarly, (7 × 3) + 1 = 22 (22 × 3) + 1 = 67
Hence, "67" is the correct answer.
Here, in all rows: (sum of 1st & 2nd term) ² = 3rd term.
6+7= 13, 13×13 = 169
10+9=19, 19 × 19 = 361
8+3=11, 11 × 11 = 121
Hence, "121" is the correct answer.
logic:- In all rows
√1st No. × 3rd No. = 2nd No. 1st Row :- √11 × 11 = √121 = 11 2nd Row :- √4 × 9 = √36 = 6 Similarly, 3rd Row :- √27 × ? = 9 ⇒ ? = 3
Hence, "3" is the correct answer.
1st row: 7(13 - 1) = 7 × 12 = 84
2nd row: 4(19 - 1) = 4 × 18 = 72
Similarly, 3rd row: 8(14 - 1) = 8 × 13 = 104
Hence, "104" is the correct answer.
(Difference of 1st & 2nd term) x 2 = 3rd term.
(86 - 49) 2 = 74
(105 - 75) 2 = 60
Similarly, (93 - 64) 2 = 58
Hence, "58" is the correct answer
