(A) 648
(B) 1,800
(C) 2,700
(D) 10,800

6 machines produce 270 bottles per minute;
1 machine produces 270/6=45 bottles per minute;
10 machines produce 45*10=450 bottles per minute;

In 4 minutes 10 machines produce 450*4=1,800 bottles.

Productivity per machine = x

6x = 270

x = 270/6 per minute

Production by 10 machines in 4 minutes = 10 * 270/6 * 4 = 1800
