Question : The following table shows the yearly production of scooters (in thousands) in different factories. In which year the total production of scooters from all factories was equal to the yearly average number of scooters produced during 2015-2019?
Option 1: 2015
Option 2: 2017
Option 3: 2016
Option 4: 2018
Correct Answer: 2015
Solution : Yearly average number of scooters produced during 2015-2019 = $\frac{115+149+101+108+102}{5}$ = $\frac{575}{5}$ = 115 The total production of scooters from all factories was equal to the yearly average number of scooters produced during 2015-2019 in the year 2015. Hence, the correct answer is 2015.
Question : A 200 m long train is running at a speed of 100 km/hr. In how much time will it pass a man standing near the railway line?
Option 1: 10.4 sec
Option 2: 9.2 sec
Option 3: 7.2 sec
Option 4: 6.4 sec
Correct Answer: 7.2 sec
Solution : Length of train = 200 m Speed of train = 100 km/hr 1 km/hr = $\frac{5}{18}$ m/sec 100 km/hr = $100 \times \frac{5}{18}=\frac{250}{9}$ m/sec Time = $\frac{\text{Distance}}{\text{Speed}}=\frac{200}{(\frac{250}{9})}=7.2$ sec Hence, the correct answer is 7.2 sec.

Option 1: 1024 cm2
Option 2: 384 cm2
Option 3: 576 cm2
Option 4: 1296 cm2
Correct Answer: 1296 cm2
Solution : The volume of a cube is given by the formula \(V = a^3\), where \(a\) is the edge length of the cube. Given that the volume of the cube is 5832 cm3. $a = \sqrt[3]{V} = \sqrt[3]{5832} = 18 \, \text{cm}$
