Answer» Correct Answer - Option 1 : Quantity 1 > Quantity 2 Given: Radha = 50% more efficient then shyam Calculations: The ratio of the efficiency of radha and shyam = 3 : 2 ⇒ The total units of work = 240 units ⇒ the number of days, radha will take = 240 / 3 ⇒ Number of days radha will take = 80 days ⇒ the number of days, shyam will take = 120 (∵ 240/2 = 120) Quantity I: 200% of the work = 200% of 240 ⇒ 480 units The number of days, radha alone will take = 160 days (∵ 480/3 = 160) Quantity II: 50% of the work = 120 units ⇒ The number of days, radha and shyam together will take to complete ⇒ 120 / 5 ⇒ 24 days ∴ Quantity I > Quantity II |
