Answer:
mark me as brainlist please
Step-by-step explanation:
Total cost of 5 app and 4 mangoes = 36 * 9 = 324.
Total cost of 7 app and 8 mangoes = 15 * 48 = 720.
5 app + 4 mangoes = 324
7 app + 8 mangoes = 720.
....................................................
12 app + 12 mangoes = 1044..............................adding both equation .
2(12 app + 12 mangoes) = 1044 * 2....................Multiplying by 2.
24 app + 24 mangoes = 2088.
