Solution

We use vertical bars to represent numerical values using tally marks, where one bar represents value $1$ , two bars shows $2$ and so on. To represent $5$ , we use four vertical bars and one crossed bar.
Therefore,
(a) $I I I I$ $I I$ $= 5 + 2 = 7$
(b) $I I I I$ $I I I I$ $I I$ $= 4 + 4 + 2 = 10$
(c) $I I I I$ $I I I$ $= 5 + 3 = 8$
(d) $I I I I$ $I I I I$ $I I I I$ $I I$ $= 5 + 5 + 5 + 2 = 17$
Hence, $(a)$ $\to$ $(i v)$ , $(b) \to (i i i)$ , $(c) \to (i i)$ , $(d) \to (i)$ .
