Question

The sum of 437, 374 and 743 is divisible by 14.

• A. True
• B. False

Answer 1

The correct option is A

True

In 3 digit number abc
abc = 100 a + 10b + c

bca = 100 b + 10c + a

cab = 100 c + 10 a + b

On adding all three , we get . 111a + 111b + 111c

So 111( a+ b + c)

Here we have a = 4 , b = 3 and c = 7

$\therefore$ 111 ( 4 + 3 + 7 ) = 111 $\times$ 14

Hence the sum of given numbers is divisible by 14.
