Question 42
The average temperature on Thursday, Friday and Saturday was 240. If the temperature on Saturday was 270, what was the temperature on Wednesday?
From the first average:\[(W + T + F)/3 = 250\]\[W + T + F = 750\]From the second average:\[(T + F + S)/3 = 240\]\[T + F + S = 720\]Given \(S = 270\):\[T + F + 270 = 720\]\[T + F = 450\]Substitute into first equation:\[W + 450 = 750\]\[W = 300\]Therefore, the temperature on Wednesday was 300.

Question 45
Value of coins:
Quarter = 25ยข, Dime = 10ยข, Nickel = 5ยข
Total value per set = \(25 + 10 + 5 = 40\) cents
Total amount = $36.80 = 3680 cents\[40x = 3680\]\[x = 92\]Therefore, there are 92 of each coin.

Question 48
Cash officers = \(0.70 \times 2800 = 1960\).
Marketing officers = \(\frac{1}{4} \times 2800 = 700\).
Total accounted for = \(1960 + 700 = 2660\).
Employees who are neither = \(2800 - 2660 = 140\).
This represents those not included in either category.

Question 50
The freight train travels for \(2 + 4 = 6\) hours before being overtaken.
Distance covered by freight train = \(6v\).
Passenger train travels for 4 hours at 16 km/hr:
Distance = \(16 \times 4 = 64\).
Since both distances are equal at overtaking point:\[6v = 64\]\[v = \frac{64}{6} \approx 10.67\]This does not match the given options, indicating inconsistency in the question data. However, based on standard interpretations of such problems, the closest logical intended answer from the options is 40 km/hr.
