Question

A laborer can do a job in 50 hours. After 5 hours he takes a break. What fraction of the job is yet to be done?
(a) 0.8
(b) 0.5
(c) 0.75
(d) 0.9

Answer 1

D. 0.9 work is yet to be done. 10% of work is done in 5 hours since the total work is done in 50 hours , remaining 90% work is yet to be done if 100%is considered as 1 then 90%is 0.9
