<result>E</result>
a can complete a certain job in 16 days. b is 60 % more efficient than a. in how many days can b complete the same job?
divide(multiply(16, 60), const_100)
let , total work unit = 160 units a can finish in 16 days = 160 unit work i . e . a can finish in 1 days = 10 unit work i . e . b can finish in 1 days = 10 + ( 60 / 100 ) * 10 = 16 unit work days in which b will complete the work alone = 160 / 16 = 10 days answer : option e
