from figure 7μf and 3μf are in parralell so total capacitance = 10μfnow 10 ,10 and 15 μf are in series so equivalant capacitanceC = 110+110+115 =15+115    = 15×515+5 =154μfnow this capacitance is parrallel with z ,so equivalant capacitance is Ceq = 154μf+zμfwe know that energy is given as E=12Ceq V2given that  E =160 ×10-3 and V =200so 160×10-3=12(154+z) ×2002154+z =160×2×10-340000=8×10-6z = (8-154)μf =z =174μf   anss
