Bar chart of steel imports (thousands of tons, axis 20 to 44) for January to June, with bars for coil, sheet and scrap each month; the table gives the bar heights read from the chart.
From UPSC's question paper.

By how much (measured in thousands of tons) did the import of sheet steel exceed the import of coil steel in the first three months of the year?

Answer & explanation

Answer: (c) 19

Add the January–March bars: sheet 40 + 37 + 36 = 113 and coil 30 + 31 + 33 = 94 thousand tons. Sheet exceeds coil by 19 thousand tons.

  1. Sheet, January–March: 40 + 37 + 36 = 113 thousand tons.
  2. Coil, January–March: 30 + 31 + 33 = 94 thousand tons.
  3. Excess = 113 − 94 = 19.
  4. Check month by month: 10 + 6 + 3 = 19.

Remember · For a total difference over several months, add the month-by-month gaps; it is quicker and cross-checks the totals.
