For each set, given below, state whether it is finite set, infinite set or the null set:
viii. {coins used in India}
Step: Check whether the given set is finite, infinite or null set
Given set: {coins used in India}
The number of coins used in India is countable and limited.
And we know that a set is said to be finite set, if it has a countable number of elements in it.
Hence, the given set is a finite set.
