((wl^3)/(48EI))/((5wl^3)/(384EI)) = 384/(5*48) = 8/5.

POINT LOAD = WL^3/48EI.
UDL = 5WL^3/384EI.
UDL = 5WL^3/384EI.

Deflection for center load = WL^3/48EI.
Deflection for udl load = 5WL^3/384EI.
Ratio of both load = 8/5.
Deflection for udl load = 5WL^3/384EI.
Ratio of both load = 8/5.

At point load = WL^3/48EI.
At uniformly distributed = 5WL^3/384EI, So.
Ratio is= 8/5.
At uniformly distributed = 5WL^3/384EI, So.
Ratio is= 8/5.

Point load WL^3/3EI.
UDL 5WL^3/384EI.
RATIO IS 8/5.
UDL 5WL^3/384EI.
RATIO IS 8/5.

Maximum deflection of a uniform loaded simple beam is (5FL^4)/384EI not (5FL^3)/384EI.

Ya deflection on UDL beam is (5wl^4)/384EI.

Yes, but according to the question, W = wl which means total load.
Now, W becomes 5wl^3/384EI.
Now, W becomes 5wl^3/384EI.

Deflection for center load = WL^3/48EI.
Deflection for udl load = 5WL^3/384EI.
Ratio of both load = 8/5.
Deflection for udl load = 5WL^3/384EI.
Ratio of both load = 8/5.
