1. The average temperature on Wednesday, Thursday and Friday was 25°. The average temperature on Thursday, Friday and Saturday was 24°. If the temperature on Saturday was 27°, what was the temperature on Wednesday?
Total temperature on Thursday, Friday and Saturday was 24 × 3 = 72°
Hence, difference between the temperature on Wednesday and Saturday = 3°
If Saturday temperature =27°, then
Wednesday's temperature = 27 + 3 = 30°
Solution:
Total temperature on Wednesday, Thursday and Friday was 25 × 3 = 75°Total temperature on Thursday, Friday and Saturday was 24 × 3 = 72°
Hence, difference between the temperature on Wednesday and Saturday = 3°
If Saturday temperature =27°, then
Wednesday's temperature = 27 + 3 = 30°
