Answer 2

Answer :

• Yes , 1242 is divisible by 3 .

★ Divisibility rule of 3 :

• To know whether a number is divisible by 3 or not we need to sum up the number given , which means we need to sum up each digit and check whether the sum obtained is multiple of 3 or not .

→ Here , 1242 = 1 + 2 + 4 + 2 = 9 and 9 is multiple of 3 , which means 1242 is divisible by 3 .

• Let us take two more examples to understand :

1. 3728 = No , it is not divisible by 3 because the sum of digits turns out to be 20 and 20 is not a multiple of 3 . Therefore , given number is not divisible by 3 .
2. 564 = Yes , it is divisible by 3 because the s of digits turns out be 15 , which is a multiple of 3 , therefore , given number is divisible by 3 .
