Step-by-step explanation:
Given that there are two bricklayers.
In 9 hours, the first bricklayers built a certain wall and other bricklayer takes 10 hours to build the wall.
Let b = the number of bricks of the wall.
The number brick laid in 9 hour by first bricklayer is b
Then the number brick laid in 1 hour by first bricklayer is .
The number brick laid in 5 hour by first bricklayer is .
The number brick laid in 10 hour by second bricklayer is b

If they worked together for 5 hours,then (5×10)=50 less bricks were laid by them.
The number of brick were laid by them is .
But the wall made by b number of bricks.
According to the problem,
[ The L.C.M of 9 and 10 is =10]
Therefore the wall contained 900 bricks.
