Question 3 (b)
Using divisibility test, determine whether the given number is divisible by 6:
1258
Divisibility rule for 6: If a number is divisible by 2 and 3 both, then it is divisible by 6 also.
Applying the above divisibility rule, we get,
1258 → Divisible by 2 as its units place is an even number.
1258 → Not divisible by 3 as the sum of its digits (= 16) is not divisible by 3.
Since the number is not divisible by both 2 and 3, therefore, it is not divisible by 6.
