Working alone

Tom and Chandri are doing household chores. Chandri can do the work twice as fast as Tom. If they work together, they can finish the work in 5 hours. How long does it take Tom to work alone to do the same work?

Correct answer:

T =  15 h

Step-by-step explanation:

C = T/2  5(1/C + 1/T) = 1 5(2/T + 1/T) = 1 5 3/T = 1 T=5 3=15 h  C=T/2=15/2=215=7.5 h  x=5 (1/C+1/T)=5 (1/7.5+1/15)=1 x=1
