Given :
Total time = 5 2/3
Science and Mathematics = 2 4/5
According to the question :
❍ Total time = 5 2/3
=> 5 × 3 + 2 / 3
=> 15 + 2 / 3
☃️=> 17 / 3
❍ Time for Science and Mathematics = 2 4/5
=> 2 × 5 + 4 / 5
=> 10 + 4 / 5
☃️=> 14 / 5
❍ Time for other subjects = ( 17 / 3 - 14 / 5 ) [ LCM for 5 and 3 = 15 ]
=> ( 17 × 5 / 15 - 14 × 3 / 15 )
=> 85 - 42 / 15
=> 43 / 15
☃️=> 2 13/15
❥ So, It's Done ❥ !!
