Answer 1

Answer:

Step-by-step explanation:

Fraction  of work done by Rohan in one day = 1/9

Fraction  of work done by Titu in one day = 1/8

Rohan goes away three days before job is finished.

Fraction  of work done by Titu in three day = 3/8

Remaining work = 1 - (3/8) = 5/8

Fraction  of work done by Rohan & Titu in one day = 1/8+1/9 = 17/72

5/8 work is done jointly by Rohan and Titu

Number of days required = (72/17)*(5/8) = 72*5/17*8 = 9*5/17=45/17

Total number of days = 3 + 45/17 = 51/17 + 45/17 = 96/17
