5 / 8 th of a job is completed in 10 days . if a person works at the same pace , how many days will he take to complete the job ?
explanation : solution : it is given that 5 / 8 th of the work is completed in 10 days . = > remaining work = 3 / 8 th of total applying unitary method : total work will be completed in 10 * 8 / 5 days = > it takes 16 days to complete total work = > hence , remaining work days = 16 - 10 = 6 days answer : c
multiply(multiply(subtract(const_1, divide(5, 8)), 10), divide(8, 5))
