three no.is 3,5,7 so p=3,q=5,r=7
here q-p = 2
we can check by adding all three elements a+b+c , there sum is = 15
so 2 statement is sufficient
now average of three prime number are (a+b+c)/3 = 15 /3 = 5
now median formula is (n+1)/2 term = (3+1)/2term = 2nd term = (that is 5 ) 5
so their median (5) is the average of 3 prime number (5) .
so 1 is also satisfied
ans = 1 and 2 both are sufficient .
thanks

Everyone is wrong here
ques 1: - either of the statement is sufficient

ques 2:- only 2 statement satisfy-

consecutive prime no.- 2,3,5,7,11....47,53,59

1) 3+5+7=15/3=5
47+53+59=159/3=53
Thus, statement not satisfied

2) only 3+5+7=15
Thus, statement satisfied.
