IIT JEE past question Thermodynamics 3

A monoatomic ideal gas of two moles is taken through a cyclic process starting for A as shown in the figure .The volume ratios are VB/VA=2 and VD/VA=4. If the temperature TA at A is 27 degree C, calculate
a) The temperature of gas at point B
b) Heat absorved or released by the gas in each process
c) The total work done by the gas during the complete cycle.

Express answer in terms of R.

Diagram coming in a bit ;)

"VD/VC=4."

seems to b a typo ^^^

coz frm diag. Vc = Vd

Is it Td/Tc = 4 ??

using geometrical concept
Tb/Ta = Vb/ Va
Tb = 300 * 2 = 600K
