Answer 1

As given in the question,

The ratio of sand to gravel used for making a concrete walkway is

2 to 3.

Now, if we increase the quantity of one thing, the quantity of the second thing should also increase in the same proportion.

Now,

new quantity of sand = 8

new quantity of gravel = y

Using the above-mentioned definition, we can write:

`(2)/(3)=(8)/(y)`
`y\text{ = }(8)/(2)\cdot3`
`y\text{ = 12}`

Therefore, option B is correct.
