The mean of `m+3a , m+a , m , m-a , m-3a` is:

The arithmetic mean of numbers a, b, c, d, e is M. What is the value of (a-M)+(n-M)+(n-M)+(d-M)+(e-M) ?

The mean of 1,7,5,3,4 and 4 is m. The numbers 3,2,4,2,3,3 and p have mean m-1. Find m and p.

Find the value of m ( m -1 )/3 - ( m -2 )/4 = 1

If M + N means M is brother of N, M/N means M is father of N and M x N means M is sister of N. Which of the following means A is uncle of B ?

A bird moves from point (1 m, -2 m, 3 m) to (4 m, 2 m, 3 m) . If the speed of the bird is 10 m//s , then the velocity vector of the bird in m//s is:

If m=- 4 , n=-2 then the value of m^3 - 3m^2 + 3m + 3n + 3n^2 + n^3 is

The three initial and final positions of a man on the x-axis are given as (i) (-3 m, 7 m) (ii) (7 m, -3 m) (iii) (-7 m, 3 m)
