Hello. I think the answer is N1.05.

both cost N2.10k
the book is N2 more than the pen
which means the book is N2.5k
==> The pen should cost 5k

Unless there is another way in solving it.

its simply 10kobo

..

From my own point of view
Let
book = x
Pen = y

A book and a pen cost N2.10
x + y = 2.10

If the book cost N2 more than the pen
x + 2 = y

Solving simultaneously gives
x = 0.05
y = 2.05

So the book cost N0.05 and the pen, N2.05

The book cost N2.00 and the pen N0.05
