work completed by gautam in hrs = 5
work completed by gautam in 1 hr = 1/5
work completed by gambhir in hrs = 6
work completed by gambhir in 1 hr = 1/6
If they work together, work completed in 1 hour = 1/3 + 1/6
= 2 + 1/6
= 3/6
= 1/2
work completed by them in hours =
= 1 ÷ 1/2
= 1 × 2/1
= 2 hours.
So, if they both will work together, the work will finish in 2 hours.
