Question

Rohon can do a job in 9 days and Tito in 8 days. They begin together but Rohan goes away 3 days before the job is finished. how long does the job lost?solve it​

Answer 1

Answer:

Rohan does (1/9)th of the work in 1 day while Tito does (1/8)th in 1 day.

Suppose the work was completed in x days. It that period, Rohan worked for x days and Tito for (x-3) days.

The equation we have is

(x/9)+(x-3)/8 = 1, or

8x + 9x-27 = 8*9 = 72

17x = 72+27 = 99, or

x = 99/17 or 5 and 14/17 days.

The work is done in 5 and 14/17 days. Answer.
