aliina [53]

Answer:

£152.

Step-by-step explanation:

We have been given that a bottle contains 255 coins. 1/3 of the coins are  £1.00.

Let us find 1/3 of 255 to find the number of £1 coins.

\£1\text{ coins}=\frac{1}{3}\times 255

\£1\text{ coins}=85

This means we have £85.

We are also told that 110 of the coins are 50 p coins.

\text{Value of 50 p coins}=\£0.50\times 110

\text{Value of 50 p coins}=\£55

Let us figure out number of 20 p coins by subtracting the number of £1 coins and 50 p coins from 255.

\text{Number of 20 p coins}=255-(85+110)

\text{Number of 20 p coins}=255-(195)

\text{Number of 20 p coins}=60

\text{Value of 20 p coins}=\£0.20\times 60

\text{Value of 20 p coins}=\£12

Now let us find total value of the coins contained in the bottle by adding the values of £1 coins, 50 p coins and 20 p coins.

\text{The total value of the coins}=\£85+\£55+\£12

\text{The total value of the coins}=\£152

Therefore, the total value of the coins contained in the bottle is £152.
