14 1/3 days ???

·  15h

Let total unit be 36 so A will do 36/12 = 3 unit in 1 day and B at his regular efficiency will do in 1 day as 36/18 = 2 units...Now working two days alternatively (3+3)+(2+2)+(3+3)+(2+2)+(3+3)+(2+2)+(3+3)= 36 units in total 14 days

Let tony works for x hours then jon works for (3/4)x hours.let wage of Tony be y/hr then Jons pay will be( 6/5)y/hr . Therefore Jons pay =(3/4)x*(6/5)y=480.Find pay of Tony= xy =480/((6/5)*(3/4))=533.33₹
