If you share the costs of a meal on the ratio of 2: 3 and one person pays £52.20 how much was the whole meal?

The ratio of shared costs of mean=2:3.
One person paid the cost £52.20, so let the other person paid the cost be X.
(2/3)=(52.20/X)
X=(52.20×3)/2
X=26.10×3
X=78.30
So the gross cost paid by both the person = £(78.30+52.20)
⇒£130.60
