Let x be the number, then 60 = 40% of x & x =60/40%=60/0.4=150 then the number of which 60 represent 40% of it is 150 2) Let x be the time needed to the 16 clerks to finish the job
In one day the 32 clerks complete a portion of 32/22 of the job In one day the 16 clerks complete a portion of 16/x of the job So in 1 day===> 32/22 =16/x ==> x=(22*16)/32 = 11 days
