The average temperature on Wednesday, Thursday and Friday was 25°C. The average temperature on Thursday, Friday and Saturday was 24°C. If the temperature on Saturday was 27°C what was the temperature on Wednesday?
সমাধান
সঠিক উত্তর: Option D
Thurs + Fri + Sat = 24 * 3 = 72
Sat = 27
So, Thurs + Fri = 72 - 27 = 45
Again,
Wed + Thurs + Fri = 25 * 3 = 75
or, Wed = 75 - (Thurs + Fri)
or Wed = 75 - 45
= 30
