Question : The following table shows the number of delivery partners (in thousands) who joined five different companies during six different years.
Find the ratio of the number of delivery partners who joined Clipkart (in 2019 and 2020) to the number of delivery partners who joined Tomato (in 2019 and 2020).

Option 2: 3 : 2
Option 3: 1 : 2
Option 4: 2 : 1
Correct Answer: 2 : 1
Solution : In 2019 and 2020 the number of delivery partners joined Clipkart = (5600 + 6400) = 12000. In 2019 and 2020 the number of delivery partners joined Tomato = (2700 + 3300) = 6000. So, the required ratio = 12000 : 6000 =
Question : Ankit went to Manali, for river rafting. He rows at the rate of 12 km/h in still water. To cover the same distance, it takes him twice as long to row up as to row down the river. Find the rate of flow of the river.
Option 1: 6 km/h
Option 2: 4 km/h
Option 3: 8 km/h
Option 4: 2 km/h
Correct Answer: 4 km/h
Solution : Let the rate of flow of water of the river be $x$. Speed of boat in still water = 12 km/h Let the distance be $y$ km. According to the question, $\frac{y}{12-x}=2 × \frac{y}{12+x}$ ⇒ $12+x=24-2x$ ⇒ $3x=12$ ⇒ $x=4$ Hence, the correct answer

Question : A large solid cube is melted and cast into ' N ' small solid spheres, each of radius 3 cm, and ' N + 2 ' small solid cuboids, each of dimensions 4 cm × 4 cm × 6.5 cm. If the length of each side of the large solid cube is 12 cm, then find the value of 'N'. [Use $\left.\pi=\frac{22}{7}\right]$
Option 1: 8
Option 2: 5
Option 3: 7
Option 4: 6
Correct Answer: 7
Solution : According to the question, Volume of cube = volume of N-solid spheres + Volume of (N + 2) small cuboids ⇒ $12 \times 12 \times 12 =[ N \times \frac{4}{3}\times\pi\times 3^3] + [(N + 2)(4 \times 4 \times 6.5)]$ ⇒ $1728 = 36N\pi + 104N
