Correct Answer: 7 : 4
Solution :
From the table,
The time invested by the teacher in 'teaching and reading' = 8 + 6 = 14 hours
The time invested in 'sleep and play' = 7 + 1 = 8 hours
The ratio between the sum of time invested by the teacher on 'teaching and reading' and 'sleep and play' = 14 : 8 = 7 : 4
Hence, the correct answer is 7 : 4.
