If seven numbers, each divisible by 4 are
added, the sum will be divisible by
a) 7
b) 4
c) 28
d) 9
​

Answer 1

Answer:

b) 4

Step-by-step explanation:

A + B + C + D + E + F + G

= 4(h) + 4(j) + 4(k) + 4(l) + 4(m) + 4(n) + 4(o)

= 4(h + j + k + l + m + n + o)

Remaining number must be divisible by 4 as it is a factor.

The resulting number may or may not be divisible by the other options but we know for sure that it will be divisible by 4.
