The product of two consecutive odd numbers is 19043. Which is the smaller number? (a) 137 (b) 131 (c) 133 (d) 129 (e) None of these

Let x be the smaller of the two consecutive odd positive integers. Then, the other integer is x + 2. Since both the integers are smaller than 10, x + 2 <...

(c) From the given alternatives, 112 × 114 = 12768 Larger number = 114

(b) A + A + 2 + A + 4 + A + 6 = 180 4A + 12 = 180 A = 42. Next four consecutive even numbers are 50 + 52 +...

? = 333 × 131 = 43623

 (a) According to the question,  x + x + 2 + x + 4 + x + 6 + x + 8 = 140  or, 5x + 20 = 140  or, 5x =...

(a) From the given alternatives, 1763 = 43 × 41

(d) Let the smaller number be x  x (x + 2) = 5358  x2 + 2x – 5328 = 0 (x + 74) (x – 42) = 0  x = 72 

(b) Let the numbers be x and (x + 2)  Then, x × (x + 2) = 582168  x 2 + 2x – 582168 = 0  x2 + 764x – 762x – 582168 =...

(d) Let the two numbers be x and (x + 2).  Then, x2 + (x + 2)2 = 6500  x2 + x2 + 4x + 4 = 6500  2x2 + 4x – 6496...

(d) The series is + (7)2, + (6)2, + (5)2, + (4)2, + (3)2 The wrong number is 102. It should be 68 + (6)2 = 104
