(C) First,calculate the total time taken by each person in hours:Ram's total time $= 15 	ext{ days} 	imes 8 	ext{ hrs/day} = 120 	ext{ hrs}$.Fari's total time $= \frac{20}{3} 	ext{ days} 	imes 9 	ext{ hrs/day} = 60 	ext{ hrs}$.Now,calculate the combined rate of work per hour:Combined work per hour $= \frac{1}{120} + \frac{1}{60} = \frac{1+2}{120} = \frac{3}{120} = \frac{1}{40} 	ext{ of the work per hour}$.So,they finish the work together in $40 	ext{ hrs}$.Given that they work $10 	ext{ hrs/day}$,the number of days required is:$	ext{Days} = \frac{40 	ext{ hrs}}{10 	ext{ hrs/day}} = 4 	ext{ days}$.

Ram can finish a work in $15 \text{ days}$ working $8 \text{ hrs/day}$. Fari can finish it in $6 \frac{2}{3} \text{ days}$ at $9 \text{ hrs/day}$. Find in how many days both can finish it together,if both work $10 \text{ hrs/day}$?
