Direction( 1- 10): What will come in place of question mark in below given questions:-

SOLUTIONS

1.   (3) Here we get the lowermost term by adding the two up- permost terms of the square and doubling it .

            As, (1 + 2) × 2 = 6

            (3 + 2) × 2 = 10,

            Similarly,

            (3 + 4) × 2 = 14.

 2.   (1) Here the number series is as follows-

            22 ­–3 = 1

            12 – 2 = –1

             32 – 4  = 5.                          

3. (2) 5× 6 + 3 × 3 = 39 and,

          7 × 5 + 4 × 4 = 51

          5 × 5 + 3 ×  4  =  37

4.   (3) 9 + 7 – 5 = 11 and,

             6 + 4 – 8 = 2

             8 + ? – 4 =  7

 5.   (3)  4 + 9 + 17 + 6 = 36

                20 + 5 + 8 + 9 = 42

                7 +  23 + 9 + 9 = 48

                 9 + 4 + 19 + ? = 40

                ® ? = 40 – 32 = 8

6.   (3)   13 × 17 = 221

                12 × 19 = 228

                13 × 18 = 234

7.   (2) 3 × 3 = 9, 9 × 3 = 27, 27 × 3 = 81

            6 × 3 = 18, 18 × 3 = 54, 54 × 3 = 162

            7 × 3 = 21, 21 × 3 = 63, 63 ×  3 = 189

8.   (3)  5 + 0 = 5, 5 + 3

            =  8, 8 + 3 = 11

            7 – 3 = 4, 3 + 5 = 8, 8 – 2 = 6

            3 + 6 = 9 and 6 + 4 = 10

            1 + 0 = 0 = 1 and 0

9.   (2)   1+ 2 + 4 + 3 = 10;

                10 × 5 = 50

                 3 + 4 + 5 + 2 = 14;

                 14 × 5 = 70

                  7 + 4 + 9 + 3 = 23;

                     

10.   (1)   (3)2 + (2)2 + (1)2

                      = 9 + 4 + 1 = 14

                         (4)2 + (3)2 + (2)2

                      = 16 + 9 + 4 = 29

             Similarly,

            (5)2 + (4)2 + (3)2

                                = 25 +16 + 9 = 50
