Average temperature for Wednesday, Thursday and Friday = 40° C Total temperature = 3 × 40 = 120° C Average temperature for Thursday, Friday and Saturday = 41° C Total temperature = 41 × 3 = 123° C Temperature on Saturday = 42° C Now, (Thursday + Friday + Saturday) – (Wednesday + Thursday + Friday) = 123 – 120; Saturday – Wednesday = 3 Wednesday = 42 – 3 = 39° C
