The number of even numbers greater than 1000000 that can be formed using all the digits 1,2,0,2,4,2 and 4 is 

Answer:

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
