Answer:
Option C
Explanation:
The numbers greater than 1000000 that can be formed using all digits 1,2,0,2,4,2 and 4 is $\frac {7!}{3! 2!}- \frac{6!}{3! 2!}$ =360
The odd numbers greater than 1000000 that can be formed by using 1,2,0,2,4,2 and 4 is $\frac{6!}{3! 2!}-\frac{5!}{3! 2!}$=50
$\therefore$ Total even number =360-50=310
