Answer 1

Hey there!
Praneeth from brainly.in here to help!

The first two digit number is 10
The last two digit number is 99

So,the number of two digits number=99-10+1
=90 [The number of numbers from a to b is( b-a+1),b>a]

So,there are 90 numbers which exactly have 2 digits

Hence correct option is Option d
Answer➡90

Hope helped!
