Question

A bottle contains 255 coins. 1/3 of the coins are ?1.00. 110 of the coins are 50p coins. the rest are 20p coins. work out the total value of the coins contained in the bottle.

Answer 1

Answer:

Step-by-step explanation:

£1 coins= 1/3 x 255

£1 coins= 85

That means we have £85

Value of 50p coins= £0.50 x 110

Value of 50p coins= £55

Figure out number of 20p coins by subtracting the number of £1 coins and 50p coins from 225  

Number of 20p coins= 225-(85+110)

number of 20p coins=225-(195)  

Number of 20p coins= 60

Value of 20p coins=£0.20 x 60

Value of 20p coins=£12

The total value of coins= £85+£55+£12

the total value of coins=£152

Answer 2

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.
