statement 2 : 4 hours of x = 2( 3 hours of y)

Shouldn't it be twice?

Let the rate of m/c X be x bottles/hour

Let the rate of m/c Y be y bottles/hour

So in 4 hours m/c X will produce = 4x bottles

and in 3 hours m/c Y will produce = 3y bottles.

Total bottles = 4x+3y ----(1)

Stmt1: Machine X produced 30 bottles per minute. i.e x=30bottles/min but rate of y is not given. Insufficient.

Stmt2: Machine X produced twice as many bottles in 4 hours as machine Y produced in 3 hours.

4x = 2 * 3y

y=2/3 x

Substituting in (1), 4x+ 3 * 2/3 x = 6x total number of bottles.

Now rate of m/c X is x bottles in 1 hour

so 6x bottles in 6 hours.
