If 2 men and 3 boys can do a piece of work in 8 days. In how many days will 3 men and 4 boys do it?

4 days

Step-by-step explanation:

We will solve it by this way-

2 m and 3 b can do a work in 8 days.

Then 3 m and 4 b do it in how many days.

=2*3*8=3*4*x

x=2*3*8/3*4

x=2*8/4

x=2*2

x=4 days

a)(x-2)^2+(y-1)^2=9
