Question

Ashish stiudies for 3 hours on friday 1 hour on saturday and sunday and rest 4 hours in remaining days how many hours does he studies daily an an average

Answer 1

Number of hours studied on Friday = 3 hours
Number of hours studied on Saturday and Sunday = 1 hour
And number of hours studied on remaining days = 4 hours
So average number of hours he daily studied = $\frac{\mathrm{number}\mathrm{of}\mathrm{hours}\mathrm{studied}\mathrm{on}\mathrm{friday}+\mathrm{number}\mathrm{of}\mathrm{hours}\mathrm{studied}\mathrm{on}\mathrm{saturday}\mathrm{and}\mathrm{sunday}+\mathrm{number}\mathrm{of}\mathrm{hours}\mathrm{studied}\mathrm{on}\mathrm{remaining}\mathrm{days}}{7}=\frac{3+1+4}{7}=\frac{8}{7}$
So average number of hours Ashish sudied daily = $\frac{8}{7}\mathrm{hours}=1\frac{1}{7}\mathrm{hours}$
