Directions (61-65):The line graph given below shows the number of laptops (HP and Dell) sold by Hemant in five days. Read the Line graph given below carefully and answer the following questions.

From Monday to Friday, 20% of total Dell laptops found defective while 60% of remaining remains unsold. Find the total no. of Dell laptops.

Step 1: Read the Dell laptop sales from the line graph

• Monday = 70
• Tuesday = 140
• Wednesday = 30
• Thursday = 80
• Friday = 100

Step 2: Find the total number of Dell laptops

Total Dell laptops = 70 + 140 + 30 + 80 + 100

= 420

Step 3: Find the defective laptops

Defective laptops = 20% of 420 = 84

Remaining laptops = 420 − 84 = 336

Step 4: Find the unsold laptops

Unsold laptops = 60% of 336 = 201.6 (≈ 202)

Sold, non-defective laptops = 336 − 201.6 = 134.4 (≈ 134)

Answer:

• Total Dell laptops = 420
• Defective = 84
• Unsold (after removing defective) = 201.6 ≈ 202
• Sold, non-defective = 134.4 ≈ 134

Note: The question asks to "Find the total no. of Dell laptops," which is simply 420. The information about defective and unsold laptops is not required for that answer.
