£2.80 is made up of equal numbers of coins of 5p, 10p and 20p, how many coins are there altogether
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

Since the number of coins of each nomination is the same, you can regroup the coins in groups of three coins in each: 5p + 10p + 20p. 
The worth of each group is 5p + 10p + 20p = 35p.

The number of groups is  = 8.

Hence, there are 8 coins of 5p, 8 coins of 10p and 8 coins of 20p.

In all, there are 3*8 = 24 coins.

Answer.  In all, there are 3*8 = 24 coins.
