Answer 28(B).

Here’s another smart Question. It appears to be daunting but it’s not that tough. We start

with 1 at units place. When multiplied 3 times and then divided by 2 we get 1.5. So it is

ruled out. Next we try with 2. When we multiply by 3 we get 6 which when divided by 2

gives us 3.Bingo!! We get the first number 32. Similarly by trying out different numbers

at unit place we get other 2 numbers as 64 and 96(which are also multiples of 32 for

hint). So we get a total of 3 numbers between 10 and 99.
