Which of the following CANNOT yield an integer when divided by 10?
(i) Product of two prime numbers
(ii) An integer less than 10
(iii) Sum of three consecutive integers
(iv) An odd integer
A. (i) & (iv) only
B. (ii) & (iv) only
C. (ii), (iii) & (iv) only
D. (iv) Only

• D)(iv) only
  Reason:
  (i) is false. Product of the prime nos. 2 and 5 will give 10 which is divisible by 10.
  (ii) is false. Since the negative integer -10 is divisible by 10.
  (iii) is false. Sum of consecutive integers 9,10,11 gives 30 a multiple of 10.
  (iv)is true. An odd integer is not exactly divisible by 2 so not divisible by 10.

• ans will be C i.e ii,iii,iv..
  since two prime no.s 2 & 5 when multiplied yields 10 i.e divisible by 10....so (i) is wrong
