Question : A passenger train running at the speed of 80 km/h leaves the railway station six hours after a goods train leaves and overtakes it in four hours. What is the speed of the goods train?
Option 1: 32 km/h
Option 2: 50 km/h
Option 3: 45 km/h
Option 4: 64 km/h
Correct Answer: 32 km/h
Solution : The passenger train covers the distance in 4 hours = 80 × 4 = 320 km The goods train travels this distance in = (6 + 4) = 10 hours We know that, $\text{Speed}=\frac{\text{Distance}}{\text{Time}}$ So, the speed of the goods train = $\frac{320}{10}=32$ km/h

Solution : Let's check the options – First option: 9 : 1458; (9)3 × 2 = 729 × 2 = 1458 Second option: 3 : 54; (3)3 × 2 = 27 × 2 = 54 Third option: 5 : 685; (5)3 ×
Question : Let $x$ be the smallest number which, when added to 2000, makes the resulting number divisible by 12, 16, 18, and 21. The sum of the digits of $x$ is:
Option 1: 7
Option 2: 5
Option 3: 6
Option 4: 4
Correct Answer: 7
Solution : LCM of (12, 16, 18, 21) = 1008 (less than 2000) The next number which is divisible by 12, 16, 18, and 21= (2 × 1008) = 2016 Also, 2016 is 16 more than 2000. So, (1 + 6) = 7 Hence, the correct answer
