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

Team Careers360 21st Jan, 2024

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

Team Careers360 22nd Jan, 2024

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
