The sum of 437, 374 and 743 is divisible by 14.
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
∴ 111 ( 4 + 3 + 7 ) = 111 × 14
Hence the sum of given numbers is divisible by 14.
