Question

The number of areas of study for which the critical analysis was done at friends’ place alone is at most:

• A. 2
• B. 3
• C. 5
• D. 1

Hint:

When multiple variables compete for the same time allocation, divide total resource by minimum needed per unit to get maximum units.

Answer 1

The Correct Option is A

Step 1: Critical Analysis time = 20% of total study time From first chart. 

Step 2: Place of study – Friends Place = 10% So only 10% of total time was at friend’s place.

Step 3: Max number of areas of study critical analysis could be done at friend’s place 
Assume each area takes equal time and only critical analysis done at friends’ place. Let’s allocate 5% per area → Max number = \( \frac{10\%}{5\%} = 2 \)
