1. 25.40
2. 30.33
3. 22
4. 35
5. 22.75

Answer 1

Correct Answer - Option 5 : 22.75

Given:

Time taken by Karan to do the school project is 33 days.

Efficiency of Soham is 45% more than Karan.

Formula Used:

Total work = Total number of days × Efficiency

Calculation:

Let Karan’s efficiency to complete the work be 100

⇒ Soham’s efficiency to complete the work will be 145

Now Karan took 33 days to complete the work,

⇒ Total work = 100 × 33

⇒ Total work = 3300 units

To complete 3300 units of work Karan will take,

⇒ 3300/145

⇒ 22.75 days. 

∴ Time taken by Soham to complete the school project is 22.75 days.
