(1) 56 (2) 13 (3) 8 (4) 16 (5) None of these Ans : (3) Explanation : Consider column wise, Add first two elements and divide by 2 to get third element; so, in third column 7 + 9 = 16, on dividing by 2, we get the answer as 8. 3. Complete the series : 3, 2, 11, 6 ..... 10, 27 (1) 19 (2) 14 (3) 17 (4) 42 (5) None of these Ans : (1) Explanation : See the difference between alternate numbers. 4.

Which choice provides the answer in the following: If 7 + 2 = 59, 5 + 3 = 28, 9 + 1 = 810, 2 + 1 = 13, then 5 + 4 = ? (1) 19 (2) 9 (3) 20 (4) 239 (5) None of these Ans : (3) Explanation : Here the rule, 7 + 2 = 59 comes as 7 + 2 = (7 - 2) (7 + 2) = 59 Also 5 + 3 = (5 - 3) (5 + 3) = 28 Thus 5 + 4 = (5 - 4) (5 + 4) = 19 6.

If 5 * 4 = 18, 3 * 5 = 24, 7 * 5 = 48, 9 * 8 = 85 then, 6 * 3 = ? (1) 54 (2) 18 (3) 81 (4) 45 (5) None of these Ans : (1) Explanation : (5 + 4) * 2 = 18; (3 + 5) * 3 = 24 (7 + 5) * 4 = 48; (9 + 8) * 5 = 85 Thus (6 + 3) * 6 = 54 9.

Directions (Qns. 1 to 5) : In the questions given below, certain symbols are used with the following meaning : A @ B means A is greater than B A * B means A is either greater than or equal to B A # B means A is equal to B A $ B means A is either smaller than or equal to B A + B means A is smaller than B Now in each of the following questions assuming the given statements to be true, find which of the two conclusions I and II given below them is/are definitely True ? Give answer (A) if only conclusion I is true. Give answer (B) if only conclusion II is true. Give answer (C) if neither conclusion I or II is true. Give answer (D) if neither conclusion I or II is true. Give answer (E) if both conclusion I and II are true. Explanatory Ans : - SBI - Reasoning - Ans. No. (1-5) 1.
