|---|---|---|
| January | 95 | 200 |
| February | 40 | 100 |
| March | 85 | 185 |

What is the total exports by Company X and Y in months of January and March?
565
580
575
590
590
Sum individual components directly: (95 + 100) + (85 + 100) = 195 + 185 = 380.
Exports (in crores) for Company X and Company Y in January and March. January: X=95, Y=100. March: X=85, Y=100.
Total=(XJanтАЛ+YJanтАЛ)+(XMarтАЛ+YMarтАЛ)
Sum individual components directly: (95 + 100) + (85 + 100) = 195 + 185 = 380.
Confusing months or companies, or misreading the values from the line graph (e.g., using February or April values).
Identify January values
From the chart, for January, the export value for Company X is 95 and for Company Y is 100.
XJanтАЛ=95,YJanтАЛ=100
Identify March values
From the chart, for March, the export value for Company X is 85 and for Company Y is 100.
XMarтАЛ=85,YMarтАЛ=100
Calculate sum
Sum the values for all four entries: (95 + 100) + (85 + 100) = 195 + 185 = 380.
Total=95+100+85+100=380
D is correct because the total export value is 95 (Jan X) + 100 (Jan Y) + 85 (Mar X) + 100 (Mar Y) = 380 crore.
