The average of 5 consecutive even number A, B, C, D and E is 34. What is the product of B and D?

(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 +...

(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 

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

(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 five consecutive numbers be x, x+1, x+2, x+3 and x+4 respectively.  Then, according to the question,  x + x + 1 + x + 2 + x + 3...
