Question A juice vendor has a 5 l container of orange juice. Each glass has a capacity 250 ml.
(a) How many full glasses can he serve before the container becomes empty?
1l = 1000 ml = 500 ml + 500 ml
= 250 ml + 250 ml + 250 ml + 250 ml
So, 4 full glasses can be served in 1Z.
1 l × 5 = 5 l
4 glasses × 5 = 20 glasses
Therefore, he can serve 20 full glasses before the container becomes empty.
(b) If he has already served 10 glasses, how much juice is left?
Solution:
Total juice = 5000 ml
Juice in 10 glasses = 10 × 250 ml = 2500 ml
Juice left = 5000 ml – 2500 ml 2500 ml = 21 500 ml
(c) If 250 ml of juice is sold at `25, how much will he earn by selling 5 l juice?
Solution:
We know that 20 × 250 ml = 5000 ml(5 l)
250 ml × 20 = 5000 ml
₹ 25 × 20 = ₹ 500
Therefore, he will earn ₹ 500 by selling 5 l juice.
