. (Question: 117155.0 )

Why had you not put 0 'zero' first. If we lay 0 first then answer will be 0.

Question:
If n is positive even number, then n (n+1) (n+2) is always divisible by:
Options:
A) 24
B) 7
C) 0
D) None of these
Solution:
Ans: (a) Let n =  2, 4, 6 ....

\(\therefore\) n (n+1) (n+2)

for n = 2

2 x 3 x 4 = 24

for n = 4

4 x 5 x 6 = 120

for n = 6

6 x 7 x 8 = 336


24,120,336 all are divisible by 24
