Answer is : 39 The average temperature of Monday, Tuesday and Wednesday = $40 ^ 0 c$ The sum of their days = 3 x 40 = $120^0 C$ The average temperature of Tuesday, Wednesday and Thursday = $41^0 C$ the sum of their days = 41 x 3 = $123 ^0C$ The temperature of Thursday = $42^0C$ Therefore, the temperature Tuesday and Wednesday = 123 – 42 = 81 the temperature of Monday = 120 – 81 = $39^oC$ Akilesh Kharvi ? answered Tue Oct 25 2016 12:30:00 GMT+0530 (IST) All Comments
