i need clear ans and solve  very very fast in 20 min and thank you | ᴅʏʙᴀʟᴀ ?✨؛

(a) A continuous beam ABCD is simply supported over three spans AB = 1m, BC= 2m, and CD = 2m. The
first span carries a central load of 20kN and the third span a uniformly distributed load of 30kN/m. The
central span remains unloaded. Calculate the bending moments at B and C and draw the S.F. and B.M.
diagrams.
(b) A 5m long cantilever ABC is built-in at A, partially supported at B, 3m from A, with a force of 15kN
and carries a vertical load of 30kN at C, a uniformly distributed load of 10kN.m is also applied between
A and B. Draw S.F. and B. M. diagrams of the beam, also compute the deflection of the free end C of the
cantilever. Take EI = 8x107 N.m².
