I will go with 7. And Explanation goes as

10! is divisible by 3
and between 10! and 10!+ 20 there are 6 integers divisible by 3 ( 10!+3, 10!+6, 10!+9, 10!+12, 10!+15, 10!+18)

So total 7 integers are there between 10! and 10!+20 that are divisible by 3.

Please correct me if iam wrong

I would say 6 since the problem says BETWEEN 10! and 10! + 20.

However, if it were inclusive of 10!, then the answer would be 7.

I would go for 6.
It's between 10! and 10! +20.
There are 6 numbers between 1 and 20 which can be divisible by 3.
