Question

If 5 men can do a piece of work in 20 days, in how many days could 10 men
do the same work?

Answer 1

10

Explanation:

(U can do mental calculation and guess it will be 10 ..) or else ....

Constant(k) = xy

k= 5 x 20

k= 100

Constant(k) = xy

100 = xy

100 = 10y

y= 100/10 = 10

= 10

I hope im right!!
