Answer 1

Answer:

6.4

Step-by-step explanation:

Desks                        Hours                       People

2                                    2.5                             2

x                                       4                              4

If more people then more desks and less time will be consumed

Direct variation bw People and Desks and inverse bw People and Hours

Hence

(4/2)=(2.5/4)*(x/2)

2=(2.5x/8)

2*8=2.5x

16=2.5x

x=16/2.5

x=6.4 Ans
