Detailed Solution

Concept- Each brick is attached to the neighboring brick using mortar, which is made by combining cement and sand. In this question, we are given that the vol ratio of cement to sand is 1:3 and that the vol of the mortar used is 0.24

. Taking into account that the vol of cement is x, the vol of sand will be

.
Cement to sand ratio for mortar mixture in joints is stated to be 1: 3.
To determine the amount of sand needed to make the mortar needed to lay 1000 bricks, 0.24

of the mortar mix is needed.
Assuming first that the volume of cement will be

, the volume of sand will then be

, and the total volume is given as

Therefore, we can create a mathematical formula to represent the sum of the volumes of cement and sand.

on solving gives

further solving gives value of

And all we need to do is determine the amount of sand there is

So, putting the value of

vol into

we get volume as

As a result, we determined what the volume of sand and cement will be.

and

Hence, the correct answer is option 1)
