Question 962254
They must have different rates of working
1st group:
{{{ ( 1/10 )*( 1/11 ) = 1/110 }}} = each man's rate
2nd group:
{{{ ( 1/15 )*( 1/22 ) = 1/330 }}} = each man's rate
3rd group:
{{{ ( 1/22 )*( 1/48 ) = 1/1056 }}} = each man's rate
----------------------
The rates are [ 1 job ] / [ number of days ] and are
average rates unless you know they are the same
for a certain group
