Toby picks a 6-digit number.
It is larger than 199,999 and it is a multiple of 2.
How many different numbers could he have picked?

Answer 1

Step-by-step explanation:

Basically the question is asking how many multiples of 5 there are in the range 1000\leq x \leq 9999

Answer 2

Answer: 400000 numbers

the number we need is abcdef (a ≠ 0)

becauuse abcdef > 199999 and it is a multiple of 2.

=> 200000 ≤ abcdef ≤ 999998

=> there are: (999998 - 200000)/2 + 1 = 400000 (numbers)
