Two bags had 50 kilograms of sugar each. After taking out 3 times as much sugar from bag one than bag two, bag one had half as m
OlgaM077 [116]

Answer:

Amount left in bag one = 20kg

Amount left in bag 2 = 40 kg

Step-by-step explanation:

We are told that Two bags had 50 kilograms of sugar each.

Let first bag be x and second bag be y.

Now, we are told that After taking out 3 times as much sugar from bag one than bag two, bag one had half as much sugar left as bag two.

Thus, amount taken from bag one is;

3a and amount taken from bag two is a.

Amount left in bag 1 is;

50 - 3a while amount left in bag 2 is 50 - a.

Since bag one had half as much sugar left as bag two, then;

50 - 3a = ½(50 - a)

50 - 3a = 25 - 0.5a

50 - 25 = 3a - 0.5a

25 = 2.5a

a = 25/2.5

a = 10

Thus;

Amount left in bag 1 = 50 - 3a = 50 - 3(10) = 50 - 30 = 20 kg.

Amount left in bag 2 = 50 - a = 50 - 10 = 40 kg
