If price of HP laptop is 20% more than that of Dell laptop, then find the amount he earned on Wednesday is what percentage of amount he earned on Thursday.
Correct Answer :
75%
75%
Solution :
Step 1: Read the values from the line graph
Wednesday:
HP laptops = 60
Dell laptops = 30
Thursday:
HP laptops = 50
Dell laptops = 80
Step 2: Let the price of one Dell laptop be Rs. 100.
Then, the price of one HP laptop = 20% more = Rs. 120.
Step 3: Find the earnings
Wednesday:
= (60 × 120) + (30 × 100)
= 7200 + 3000
= Rs. 10200
Thursday:
= (50 × 120) + (80 × 100)
= 6000 + 8000
= Rs. 14000
Step 4: Find the required percentage
Required Percentage = (10200 ÷ 14000) × 100
= 72.86%
Answer: 75% nearest
