There are five roads from a village to a town. In how many ways can a villager return after reaching the town?

Detailed Solution for VITEEE Maths Test - 2 - Question 28

Permutation : -  A Permutation is an arrangement of all or part of a set of objects, with regard to the order of the arrangement.

For example, Suppose we have a set of three letters :A, B and C..... each possible arrangement would be an example of permutation.

Here in this question, there are 5roads leading to a town from a village.

He can go by 5 ways and can return by 4 ways

So the number of different ways in which a villager can go to the town and return back is 5×4=20

VITEEE Maths Test - 2 - Question 37

The equation of the sphere with centre (3, 6, -4) and touching the plane
2x - 2y - z - 10 = 0 is

Detailed Solution for VITEEE Maths Test - 2 - Question 37

As the required sphere touches the plane
2x - 2y - z - 10 = 0 .....(1)
∴ Radius of the required sphere = ⊥ from the center (3, 6, -4) of the required sphere to the plane (1)

∴ The required equation of the sphere is given by
(x - 3)2 + (y - 6)2 + (z + 4)2 = 16 (Central form)
⇒ x2 + 9 - 6x + y2 + 36 - 12y + z2 + 16 + 8z = 16
⇒ x2 + y2 + z2 - 6x - 12y + 8z + 45 = 0
