Anil and Suman together can do a work in 12 days, which Anil alone can do in 20 days. If Suman alone has to do this work, he will take
Detailed Explanation:
Anil's rate: 1/20 work per day. Together rate: 1/12 work per day. Suman's rate = 1/12 − 1/20 = (5−3)/60 = 2/60 = 1/30 work per day.
Alternatively, using combined work formula: (20×y)/(20+y) = 12 → 20y = 240 + 12y → 8y = 240 → y = 30.
Therefore, Suman alone takes 30 days, making Option 3 the correct answer.
