To find the total cost of the 11 shirts, we multiply the cost of a shirt by the number of shirts:
Total cost of shirts = Cost of a shirt × Number of shirts
Total cost of shirts = £15.65 × 11
Total cost of shirts = £172.15

Next, we find the total cost spent on the ties by subtracting the total cost of the shirts from the total amount spent:
Total cost of ties = Total amount spent - Total cost of shirts
Total cost of ties = £403.51 - £172.15
Total cost of ties = £231.36
