Numbers between 1 and 100(inclusive) which are divisible by 3 or 10 are:

40

Explanation:

numbers between 1 and 100(inclusive) which are divisible by 3 or 10

= numbers between 1 and 100(inclusive) which are divisible by 3

+ numbers between 1 and 100(inclusive) which are divisible by 10

- numbers between 1 and 100(inclusive) which are divisible by 3 and 10 both

Numbers between 1 and 100(inclusive) which are divisible by 3 = 33

Numbers between 1 and 100(inclusive) which are divisible by 10=10

Numbers between 1 and 100(inclusive) which are divisible by 3 and 10 both=3

Hence, numbers between 1 and 100(inclusive) which are divisible by 3 or 10

= 33+10-3
