(b) Let the numbers be x and (x + 2)
Then, x × (x + 2) = 582168
x 2 + 2x – 582168 = 0
x2 + 764x – 762x – 582168 = 0
(x + 764) (x – 762) = 0
x = 762
(b) According to the question, x + x + 2 + x + 4 + x + 6 = 228 4x + 12 = 228 4x = 228 – 12 = 216 x =...
(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 +...
(a) Out of the given alternatives, 137 × 139 = 19043 Required smaller number = 137
(b) Quicker Approach: The unit's digit of the number 16128 is 8, From the given answer choices, 126 × 128 = 16128 Required larger number = 128
(a) According to the question, x + x + 2 + x + 4 + x + 6 + x + 8 = 140 or, 5x + 20 = 140 or, 5x =...
(d) Let the smaller number be x x (x + 2) = 5358 x2 + 2x – 5328 = 0 (x + 74) (x – 42) = 0 x = 72
(d) Lowest number of set A = 280/5 – 4 = 52 Lowest number of other set = 52 × 2 – 71 = 33 Required sum = 33 + 34...
(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) Let A = x, According to the question, A + B + C + D + E = x + (x + 2) + (x + 4) + (x + 6) +...
