Answer:
Option(A)
Step-by-step explanation:
Total time Suman studies = 5 (2/3) = 17/3 hours
Time devoted for science and mathematics = 2 (4/5) = 14/5 hours.
The time he devoted for other subjects:
= (17/3) - (14/5)
= (17 * 5) - (14 * 3)/15
= (85 - 42)/15
= 43/15
= 2 (13/15) hours.
Therefore, the time he devote for other subjects = 2(13/15) hours.
