(4 x 4)3 ÷ (512 ÷ 8)4 x (32 x 8)4 = (2 x 2)? + 4 (1) 8 (2) 12 (3) 6 (Ans) (4) 14 (5) None of these Ans : (4 x 4)3 ÷ (512 ÷ 8)4 x (32 x 8)4 = (2 x 2)? + 4 ⇒ (16)3 ÷ (64)4 x (256)4 = (4)? + 4 ⇒ (4)2x3 ÷ (4)3x4 x (4)4x4 = (4)? + 4 ⇒ (4)6 ÷ (4)12 x (4)16 = (4)? + 4 ⇒ (4)6-2+16 = (4)? + 4 ⇒ (4)10 = (4)? + 4 ⇒ 10 = ? + 4 ∴ ? = 6 3. (2√392 - 21) + (√8 - 7)2 = (?)2 (1) 4 (2) -4 (3) 12 (4) 2 (5) 6 (Ans) Ans : (2√392 - 21) + (√8 - 7)2 = (?)2 ⇒ (2 x 14√2 - 21) + (√8 - 7)2 = (?)2 ⇒ 28√2 - 21 + (√8)2 - 2 x √8 x 7 + (7)2 = (?)2 ⇒ 28√2 - 21 + 8 - 28√2 + 49 = (?)2 ⇒ - 21 + 8 + 49 = (?)2 ⇒ 36 = (?)2 ∴ ? = 6 4. 1 1/4 + 1 1/6 - 1 1/8 = ? + 1 1/12 (1) 5/24 (Ans) (2) 7/24 (3) 5/12 (4) 7/12 (5) None of these Ans : 1 1/4 + 1 1/6 - 1 1/8 = ? + 1 1/12 ⇒ 1 1/4 + 1 1/6 - 1 1/8 - 1 1/12 = ? ⇒ (1 + 1 - 1 - 1) + (1/4 + 1/6 - 1/8 - 1/12) = ? ⇒ 0 + (6 + 4 - 3 - 2/24) = ? ⇒ 0 + 5/24 = ? ∴ ? = 5/24 5. 76% of 1285 = 35% of 1256 + ? (1) 543 (2) 537 (Ans) (3) 547 (4) 533 (5) None of these Ans : 76% of 1285 = 35% of 1256 + ? ⇒ 976.6 = 439.6 + ? ⇒ 976.6 - 439.6 = ? ∴ ? = 537 Directions (Q.

(1) -1800 (2) 1450 (3) -1660 (4) 1660 (Ans) (5) -1450 Ans : [(7.99)2 - (13.001)2 + '(4.01)3]2 = ? ⇒ [(8)2 - (13)2 + (4)3]2 = ? ⇒ [64 - 169 + 64]2 = ? ⇒ (-41)2 = ? ∴ ? = 1681 (?- x - ⇒ +) ≈ 1660 8. 601/49 x 399/81 ÷ 29/201 = ? (1) 520 (2) 360 (3) 460 (4) 500 (5) 420 (Ans) Ans : 601/49 x 399/81 ÷ 29/201 = ? ⇒ 601/49 x 399/81 x 201/29 = ? ⇒ 600/50 x 400/80 x 200/30 = ? ∴ 400 = ? 420 ≈ ? 9. 441.01 - 232.99 + 1649.99 = ? + 1225.92 (1) 600 (2) 630 (Ans) (3) 660 (4) 690 (5) 720 Ans : 441.01 - 232.99 + 1649.99 = ? + 1225.92 ⇒ 441 - 233 + 1650 - 1226 = ? ⇒ 2091 - 1459 = ? ∴ ? = 623 ≈ 630 10.

(216)1/3 + (256)1/2 = ? (6)3X1/3 + (16)2X1/2 = ? 6 + 16 = ? 22 = ? Directions (Q. Nos. 11 to 15) What will come in place of question mark (?) in the following number series? 11. 15 21 39 77 143 (?) (1) 243 (2) 240 (3) 253 (4) 245 (5) None of these (Ans) Ans : - Solutions - Qn Ans -111 12. 33 39 57 87 129 (?)8 (1) 183 (Ans) (2) 177 (3) 189 (4) 199 (5) Ans : Solutions - Qn Ans -112 13. 15 19 83 119 631 (?) (1) 731 (Ans) (2) 693 (3) 712 (4) 683 (5) None of these Ans : Solutions - Qn Ans -113 14. 19 26 40 68 124 (?) (1) 246 (2) 238 (3) 236 (Ans) (4) 256 (5) None of these Ans : Solutions - Qn Ans -114 15. 43 69 58 84 73 (?) (1) 62 (2) 98 (3) 109 (4) 63 (5) None of these (Ans) Ans : Solutions - Qn Ans -115 Directions (Q. Nos. 16 to 20) In the following questions, two equations numbered I and II are given. You have to solve both the equations and give answer (1) if x > y (2) if x ≥ y (3) if x < y (4) if x ≤ y (5) if x = y or the relationship cannot be established Ans : 16. I. x2 - 11x + 24 = 0 II. 2y2 - 9y + 9 = 0 Ans : 2 I. x2 - 11x + 24 = 0 x2 - 8x - 3x + 24 = 0 x (x - 8) - 3 (x - 8) = 0 (x - 8)(x - 3) = 0 ∴ x = 8 or 3 II. 2y2 - 9y + 9 = 0 2y2 - 6y - 3y + 9 = 0 2y(y - 3) - 3 (y - 3) = 0 (2y - 3) (y - 3) = 0 ∴ y = 3/2 or 3 So, x ≥ y 17. I. x3 * 13 = x2 * 247 II. y1/3 * 14 = 294 ÷ y2/3 Ans : 3 I. x3 * 13 = x2 * 247 or x3 / x2 = 247/13 x = 19 II. y1/3 * 14 = 294 ÷ y2/3 or, (y)1/3 * (y)2/3 = 294/14 or, (y)1/3+2/3 = 21 ∴ y = 21 So, y > x 18. I. 12 * 4 / x4/7 - 3 * 4 / x4/7 = x10/7 II. y3 + 783 = 999 Ans : 4 I. 12 * 4 / x4/7 - 3 * 4 / x4/7 = x10/7 or, 48 - 12 = (x)10/7 * (x)4/7 or, 36 = (x)7 = (x)2 ∴ x = ±6 II. y3 + 783 = 999 y3 = 999 - 783 y3 = 216 Institute of Banking Personnel Selection (IBPS) Old Question Papers drive.google.com/file/d/0BwcsD4vqTLt4UTBxdWViZTFDU2M/view |
