Answer:two sets have 6 questions each

to satisfy the condition given he must attempt (2,4)or(3,3)or(4,2)

selecting 2 out of 6 from 1st set & 4 out of 6 from 2nd set=6c2&6c4

so total=6c2*6c4 ways if(2,4)

similarly if (3,3) and (4,2) it has 6c3*6c3 ways and 6c4*6c2

total 6c2*6c4+6c3*6c3+6c4*6c2=850
