If two numbers are divisible by a number,

their sum is also divisible by the number

 

16 & 20 is divisible by 4

Sum = 16 + 20 = 36

∴ 36 is also divisible by 4

 

36 & 78 are divisible by 6

Sum = 36 + 78 = 114

∴ 114 is also divisible by 6

 

100 & 25 are divisible by 5

Sum = 100 + 25 = 125

∴ 125 is also divisible by 5
