Answer:

3 indian menus

Step-by-step explanation:

If we assume that the proportions would remain the same then we can use the values provided to calculate the number of indian menus. We can use the Rule of Three in this scenario, since it is a ratio problem and we are given 3 values and a variable. We simply multiply the diagonal values and divide by the remaining value to get the variable.

20 menus   <====>   4 indian menus

15  menus   <====>   x indian menus

(15 * 4) / 20 = x

60 / 20 = x

3 = x
