The correct option is A 256 hr
Time spent in gym = 124 hours
Time spent in cycling = 223hours
Total time spent in gyming and cycling =124+223
Add the whole number and fractional part separately.
Addition of whole numbers =1+2=3
Addition of fractional part =24+23
As these are unlike fractions, convert them into the like fractions
Multiplying with 3 in the fraction 24, we get:
24=2×34×3=612
Multiplying with 4 in the fraction 23, we get:
23=2×43×4=812
Now, add the fractions
24+23=612+812 =6+812 =1412
Now, simplify the fraction
=2×72×6 =76
Now, combine both the whole part and the fractional part that equals to 376
Now, convert the mixed number into an improper fraction as follows
376=3×6+76 =18+76 =256
Hence, total time spent in the gym and cycling is 256 hr
