Satyam studies $\frac{2}{3}$ hour in the morning and $\frac{3}{4}$ hour in the evening every day. Then what is his total study time every day?
1 hour 25 min.
Total study time = 2/3 + 3/4 = 8/12 + 9/12 = 17/12 hours = 1 + 5/12 hours. 5/12 hour = (5/12)×60 = 25 minutes. So total = 1 hour 25 minutes. Hence option (D) is correct.
