Answer 2

Q:

How many four digits numbers greater than 6000 can be made using the digits 0, 4, 2, 6 together with repetition.

A) 64
B) 63
C) 62
D) 60

Answer:   B) 63 

Read Description:

Given digits are 0, 4, 2, 6

Required 4 digit number should be greater than 6000.

So, first digit must be 6 only and the remaining three places can be filled by one of all the four digits.

This can be done by
1x4x4x4 = 64

Greater than 6000 means 6000 should not be there.

Therefore, 64 - 1 = 63.
