The line graph shows the number of computers sold by dealers A and B from Monday to Saturday.
Which of the following statements is correct?
1. The total number of computers sold by dealer A on Tuesday, Thursday and Friday is 228.
2. The total number of computers sold by dealer B on Monday, Thursday and Saturday is 205.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Only 2
Each statement is tested by reading the dealer’s value for each named day from the graph and adding the three values.
1. The total number of computers sold by dealer A on Tuesday, Thursday and Friday is 228. — Incorrect. Dealer A sold 80 on Tuesday, 60 on Thursday and 78 on Friday, so the total is \(80+60+78=218\), not 228.
2. The total number of computers sold by dealer B on Monday, Thursday and Saturday is 205. — Correct. Dealer B sold 50 on Monday, 80 on Thursday and 75 on Saturday, so the total is \(50+80+75=\) 205.
