Question

3 cans and 3 pails can hold 18 liters of water. a pail can hold 1.5 liters more than a can. What us the capacity of one can?

Answer 1

Answer:

2.25 litres

Step-by-step explanation:

Let x be the capacity of can and p be capacity of pan.

p = 1.5 + x

3x + 3p = 18

3x + 3(x+1.5) = 18

6x = 18 - 4.5

x = 13.5/6 = 2.25 litres

Answer 2

The capacity of one can is 2.25 liters .

Explanation:

Let x = Capacity of one can ( in liters).

y= Capacity of one pail.

According to the given question, we have the following system of equations :

$3x+3y=18------------(1)\\\\ y=x+1.5---------------(2)$

Substitute the value of y from (2)in (1) , we gte

$3x+3(x+1.5)=18$

$x+(x+1.5)=6$  [Divide both sides by 3]

$2x+1.5=6$

$2x=6-1.5=4.5$

$x=\dfrac{4.5}{2}=2.25$

Hence, the capacity of one can is 2.25 liters .
