Answer 2

Answer:

4th builder receive ---- 6 tonnes of sand.

sand that each of the other 3 builders receive ----- 3/2 tonnes.

Step-by-step explanation:

Total amount of sand=21/2 tonnes.

Now, it is given that:

one of them receives 4/7 of the total

i.e. he receives:

4/7 of 21/2 tonnes

=4/7×21/2

=6 tonnes.

and the remaining sand is shared by 3 builders .

This means that 3/7 of total sand will be shared by the 3 builders.

i.e. they receive, 3/7 of 21/2 tonnes of sand

i.e. 3/7×21/2

=9/2 tonnes of sand.

If each share the sand equally.

Then the sand that each of the three builder receive is: 3/2 tonnes of sand.
