£25.60

Step-by-step explanation:

The cost of the adult ticket is reduced by 1/3, so the price paid for one adult ticket with the discount is 24 * (1 - 1/3) = 24 * (2/3) = £16.

Two child tickets would normally cost 2 * 12 = £24, but their prices are reduced by 60%. 60% is equivalent to 60/100, or simplified, 3/5. So the price of the two child tickets with the discount would be 24 * (1 - 3/5) = 24 * (2/5) = £9.60.

Adding the discounted adult ticket price to the discounted price of the two child tickets, we get 16 + 9.60 = £25.60 as the total price.
