A hydraulic system has small and large pistons with cross-sectional area of 3x10^-4 m^2 and 6x10^-3m^2 respectively. When a firce of 30N is applied to small piston, it pushes down the piston by 30cm. Determine pressure transmitted in the fluid?

Have a look, if it makes sense:
Explanation:
Considering Pascal's principle, pressure is transmitted entirely to the whole fluid (see the toothpaste tube effect! :-) so that:
but
BUT energy must be conserved!
so
where
So:
So:
