Hi

Approach for this question is :This question is based on inclusion exclusion principle (Set theory)
let a,b,c,d,e,f… represent set of prime numbers less than 20.

Now you have to find
a union b union c union d…

this can be found by inclusion exclusion principle.

In case you need explanation do post it.
