please solve this for me

a) Draw the phase diagram of a binary A (700 C) and B (900 C) system using below given information. . . A and B are completely soluble in liquid state. A has no solid solubility in B. Solid solubility of B in A at room temperature is 2 % and its maximum value is 20 %. Eutectic point: 35 % B; 550 C O b) Show the microstructural development upon cooling for an alloy having 5% B. Plot the cooling curve for such an alloy. c) Show the microstructural development upon cooling for an alloy having 35% B. Plot the cooling curve for such an alloy
