People "below the age of 26" cover two brackets from the passage, 0-15 (30%) and 16-25 (17.75%). Adding these gives the combined share below 26, which is then applied to the batch of 5,600 people.
Adding the two brackets, \(30\% + 17.75\% = 47.75\%\), and applying that to 5,600 gives \( 0.4775 \times 5600 = 2674 \).
So the correct answer is option (D), 2674.
"Below 36 years" covers three brackets, 0-15 (30%), 16-25 (17.75%) and 26-35 (17.25%), adding to 65%. Since this 65% equals 400 million people, that fixes the value of 1% of the state's population, which can then be applied to the 56-65 bracket (5.12%).
Since 65% of the population equals 400 million, 1% equals \( \frac{400}{65} \approx 6.1538 \) million. The 56-65 bracket is 5.12% of the population, so it comes to \( 6.1538 \times 5.12 \approx 31.50 \) million.
So the correct answer is option (C), 31.50 million.
The 56-65 bracket is 5.12% of the state's population, and this is given as 20 million people here, which fixes the value of 1% of the population for this scenario. That value can then be used to work out the 16-25 bracket (17.75%) and the 46-55 bracket (14.25%) and compare them.
Since 5.12% of the population equals 20 million, that fixes 1% of the population, and scaling the 16-25 share and the 46-55 share by this value and comparing them gives a gap of about 12.18 million.
So the correct answer is option (B), 12.18 million.
The 26-35 bracket is 17.25% of the population and the 46-55 bracket is 14.25%, a gap of 3 percentage points between them. This gap is given as 15.75 million people, which fixes the value of 1% of the state's total population.
Since 3 percentage points of the population equal 15.75 million, 1% equals \( \frac{15.75}{3} = 5.25 \) million, and the full 100% comes to \( 5.25 \times 100 = 525 \) million.
So the correct answer is option (D), 525 million.
Among the age brackets offered as answer choices, comparing their shares of the population settles which one is the largest.
Comparing the three named brackets directly, 17.75% (16-25) is higher than both 17.25% (26-35) and 14.50% (36-45).
So the correct answer is option (A), 16 to 25.
