Question

A,B,C & D are four consecutive odd integers and
their average is 42. What is the product of B & D?
(A) 1845
(B) 1860
(C) 1677
(D) 1890​

Answer 1

Answer:

let the integers be x , x+2 , x+4 , and x +6

Step-by-step explanation:

$\frac{x + x + 2 + x + 4 + x + 6}{4 } = 42 \\ \\ 4x + 12 = 168 \\ \\ 4x = 168 - 12 \\ \\ 4x = 156 \\ \\ x = \frac{156}{4}$

When x = 39

B = x +2 = 39+2

B = 41

D = x + 6 = 39 + 6

D = 45

B × D = 1845

A. 1845
