Andy is thinking of a number that has a digit less than 5 in the tens place. It has a digit greater than 7 in the ones place. Fill in the bubble next to all the numbers that could be Andy's number

Andy 's Number = {18,19,10,28,29,20,38,39,30,48,49 or 40}

Step-by-step explanation:

Here, given:

Let us assume the number on Tens place = M

The number in Units place = N

So, the actual value of the number = 10 M + N

The number can be written as MN.

Now, The value of M (Tens digit) is Less than 5.

So, M = 1, 2, 3 or 4 (0 not included)

Also, The value of N (Unit digit) is greater than 7.

So, N = 8, 9 or 0 (0 included)

So, by combining all possibilities for M and N, the possible number chosen by Andy can be expressed as MN:

Number = {18,19,10,28,29,20,38,39,30,48,49 or 40}

Any number can be chosen from the above set as all the numbers match the given restrictions.
