Adam and his dad share the cost of the meal in the ratio of 2:3. Adam's dad pays £52.20. What is the total cost of the meal

We have to calculate the total cost of the meal. We know that Adam (A) and his dad (D) share the cost of the meal in the ratio 2 : 3 and that Adam's dad pays 52.20 Pounds. So A : D = 2 : 3; A : 52.20 = 2 : 3. Using the cross products, A * 3 = 2 * 52.20; A * 3 = 104.40; A = 104.40 : 3; A = 34.80 Pounds. Finally, A + D = 34.80 + 52.20 = 87.00. Answer: The total cost of the meal is 87 Pounds.
