Answer:
50 coins
Step-by-step explanation:
We are given £1 worth of 20p coins.
Since it is known that,
£1 = 100p
i.e. £10 = 100 ×10 p = 1000p
As, we are taking 20p coins to get make the sum 1000p.
Thus, the number of 20p coins will be i.e. 50 coins
Hence, we get 50 coins to make £10 worth 20p coins.
