<output>96</output>
96 hrs   Q can complete the work in  (8 * 10)= 
<gadget id="calculator"> (8 * 10)</gadget>
<output>80</output>
80 hrs   P's 1 hour work=1/96 and Q's 1 hour work= 1/80   (P+Q)'s 1 hour's work =(1/96 + 1/80)=11/480   so both P and Q will finish the work in 480/11hrs   Number of days of 8 hours each =(480/11 * 1/8)=60/11   60/11NSWER IS 60/11
