Show answer & explanation
Correct answer: C
Concept: When a base quantity for one year is given along with its percentage growth to a target year, first scale the base to the target year to get the new total, then apply the target category's percentage share (read from the chart) to that total to isolate the category's actual value.
Large establishments had about 40 million employees in 1987 (given in the question).
Employment in large establishments grew by 60% from 1987 to 2000, so total employment in large establishments in 2000 = 40 x (1 + 60/100) = 40 x 1.6 = 64 million.
From the bar graph, the manufacturing sector's share of employment within large establishments in the year 2000 is 30%.
Manufacturing sector employees in large establishments in 2000 = 64 million x 30/100 = 19.2 million.
Cross-check: 19.2 million is exactly 30% of the 64 million total computed for large establishments in 2000, matching the share read from the chart, which confirms the result is consistent.
