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 [tex]\frac{1000}{20}[/tex] i.e. 50 coins
Hence, we get 50 coins to make £10 worth 20p coins.
