Show answer & explanation
Correct answer: B
Concept
For a row in a data table, the total across categories is found by adding every entry in that row.
The difference between two row totals is found by subtracting the smaller total from the larger total.
Application
Mumbai total = 18,000 + 16,600 + 17,800 + 18,700 + 18,200 = 89,300.
Manali total = 14,900 + 15,900 + 15,500 + 14,900 + 18,300 = 79,500.
Required difference = 89,300 − 79,500 = 9,800.
Cross-check
Subtracting the entries mode by mode gives 3,100 + 700 + 2,300 + 3,800 − 100 = 9,800, which agrees with the row-total method.
Therefore, the required difference is 9,800.
