A train running at 60 km/h takes 8 seconds to cross a pole. What is the length of the train?
Explanation: To find the length, first convert 60 km/h to meters per second: (60 × 1000)/3600 = 16.67 m/s. Distance = speed × time = 16.67 × 8 = 133.3 meters. 800 meters is incorrectly calculated using hours instead of seconds. 480 and 600 meters are common calculation errors.
If the selling price of an item is 125% of its cost price, what is the profit percentage?
Explanation: If selling price is 125% of cost price, profit is 25% of cost price. 12.5% and 15% underestimate the increase. 20% is a typical mistake from the wrong calculation.
A and B can complete a work in 10 days, B and C can do it in 12 days. If A, B, and C work together, in how many days will they finish the work?
Explanation: The combined rate is a+b=1/10, b+c=1/12, so a+b+c=11/60, and total time is 1/(11/60)=60/11 days. 22, 11, and 16 arise from inverting rates incorrectly or summing/averaging the numbers thoughtlessly.
