L of milk to 20 houses in a colony, how much milk would be left with him?​

Answer 1

Answer:

20 litre is distributed

hence he's left with 10 litre

Step-by-step explanation:

$1 \times \frac{1}{2} \times 20 = 10$

Answer 2

Let the initial quantity of milk-10xlitres,

For each 1 litre, 200 ml of water is added, so after adding water, quantity of mixture become =12x litres.

Now 6litres of mixture is sold, and 10 litres of milk is added.

So remaining quantity is (12x-6+10) (12x+4) In this final quantity, milk-10x-(12xX610x)+10=(10x+5)

So,

(12x+4)

(10x+5)

E

(25+3)

25

Solving, we get x=2

So initial quantity of milk - 10x = 20litres
