Step-by-step explanation:

Prime numbers less than 20 are 2, 3, 5, 7, 11, 13, 17 and 19.

(i) 2+3=5 (divisible by 5)

(ii) 2+13= 15 (divisible by 5)

(iii) 3+7=10 (divisible by 5)

(iv) 3+17= 20 (divisible by 5)

(v) 7+13=20 (divisible by 5)

48 = 19 + 29

Here, 19 and 29 both are odd as well as prime numbers.

Since 71 is a prime number, it has only two factors, 1 and 71.
