Question

IF
4 glasses of water = 28
2 cups of tea+1 glass of water=17
1 cup of tea+1 cup of coffee=9
2 glasses of water+1 cup of tea+1 cup of coffee=?

Answer 1

Answer:

1. As 4 glasses of water= 28,

each glass of water is 28/4= 7.

2. Let cup of tea be x, then

2x + 7 = 17

x = 10/2

Each cup of tea = 5.

3. Here, let cup of coffee be y, then

y + 5 = 9

y = 9-5

Each cup of coffee = 4

4. 2(7) + 1(5) + 1(4) = 23.

Therefore the answer is 23...
