Which of the following numbers is divisible by 4.
(i) 67920598
(ii) 618703592
(iii) 618703594
(iv) 67920590
- A(i)
- B(iii)
- C(iv)
- D(ii)
Solution & Step-by-step Explanation
A number is divisible by 4 if the number formed by its last two digits is perfectly divisible by 4.
Let's check the last two digits for each option:
(i) 67920598: Last two digits are 98.
4
98
=24.5 (Not divisible)
(ii) 618703592: Last two digits are 92.
4
92
=23 (Divisible)
(iii) 618703594: Last two digits are 94.
4
94
=23.5 (Not divisible)
(iv) 67920590: Last two digits are 90.
4
90
=22.5 (Not divisible)
Therefore, only number (ii) is completely divisible by 4.
