(i) The expression in the given conditional statement is- if p, then q.

p: The no. is odd

q: The square of the no. is odd

Thus, “if the no. is odd, then its square is even.

(ii) The expression in the given conditional statement is- if p, then q.

p: Take the dinner

q: you will get sweet dish

Thus, “If you take the dinner, then you will get sweet dish.”

(iii) The expression in the given conditional statement is- if p, then q.

p: You do not study

q: you will fail

Thus, “If you do not study, you will fail.”

(iv) The expression in the given conditional statement is- if p, then q.

p: An integer is divisible by 5

q: Unit digits of an integer are 0 or 5.

Thus, “If an integer is divisible by 5, then its unit digits are 0.”
(v) The expression in the given conditional statement is- if p, then q.

p: Any no. is prime

q: square of no. is not prime

Thus, “If any no. is prime, then its square is not prime.”

(vi) The expression in the given conditional statement is- if p, then q.

p: a, b & c are in AP

q: 2b = a + c

Thus, “If a, b & c are in AP, then 2b = a + c.”
