1.	Ullas's working capacity is twice that of Tejas. Together they can finish the work in 18 days, so in how many days Tejas will complete the same work alone?A. 36B. 54C. 20D. 721. D2. C3. A4. B
Answer» Correct Answer - Option 4 : B Given: Ratio of efficiency of Ullas to Tejas = 2 : 1 Time to complete the whole work together = 18 days Formula used: Efficiency = (Total work)/(Time Taken) Calculations: Let the efficiency of Ullas and Tejas be 2 units/day and 1 unit/day respectively. Combined efficiency of Ullas and Tejas together = 2 + 1 = 3 units/day Efficiency = (Total work)/(Time Taken) ⇒ 3 = (Total work)/18 ⇒ Total work = 54 units Time to complete the whole work by Tejas alone = 54/1 = 54 days ∴ Tejas will complete the same work alone in 54 days.

Answer» Correct Answer - Option 4 : B

Given:

Ratio of efficiency of Ullas to Tejas = 2 : 1

Time to complete the whole work together = 18 days

Formula used:

Efficiency = (Total work)/(Time Taken)

Calculations:

Let the efficiency of Ullas and Tejas be 2 units/day and 1 unit/day respectively.

Combined efficiency of Ullas and Tejas together = 2 + 1 = 3 units/day

Efficiency = (Total work)/(Time Taken)

⇒ 3 = (Total work)/18

⇒ Total work = 54 units

Time to complete the whole work by Tejas alone = 54/1 = 54 days

∴ Tejas will complete the same work alone in 54 days.
