Answer:
32, 46
Step-by-step explanation:
Remember, a is congruent to b modulo d if d divides a-b.
Now, the problem says that b=4 and d=14.
Let a=32. Observe that a-b=28 and , then 32 is congruent to 4 modulo 14.
Let a=46. Observe that a-b=46-4=42 and , then 46 is congruent to 4 modulo 14.
Answer: 70 ml of coffee in each cup
