Amit,

My take is listed below...

> 3 lines tho
>
> permit 10.0.5.0 0.0.0.255 (Permit only .5)

Correct

> permit 10.0.10.0 0.0.5.255 (Permit only .10 and .15)

A 2 bit mask (3rd octet) will allow 4 networks: .10 .11 .14 and .15

> permit 10.0.12.0 0.0.1.255 (Permit only .12 and .13)

Correct

> Let me know if this is correct?

You're close, don't forget that each bit is a don't care. Each bit in the
network part of the address adds n2 options (aka matched networks).
