Question

Please help me with this and thank You

Answer 1

`5 * 10 = 50`, so option C is surely wrong.

Moreover,
`2 * (1)/(100) = 0.02`

So, if you add the two, you have

`50+0.02 = 50.02`

which is option E. But if you add a zero after the decimal expansion of a number, the number doesn't change:

`50.02=50.020`

So option A is fine as well
