ans : destructing the bridge
if they both are doing positive work then they would have completed in less than 10 days but still they are consuming 20 days together,,so that means one of them is doing negative work.if hanuman is doing negative work then bridge wont get completed.. thus ravanan is doing negative work..and his contribution is destructing the bride

ans is D option..
hanuman is doing 2unit/day
ravanan is doing 1unit/day
therefore together they are doing 3unit/day
Total work=20units
so, they are takin 20/3 days to complete the work..But actually they are taking 20days to complete the work..So Ravanan is doing the negative work
