If the arithmetic mean of 7 numbers is 10 and the arithmetic mean of 6 numbers is 11 then the 7Nth number?
Suppose the seven numbers are a,b,c,d,e,f and g
The arithmetic mean of all 7 is 10. So the sum of all seven ie a+b+c+d+e+f+g is 10*7 = 70.
The arithmetic mean of the fist six a to f is 11. So their sum (a+b+c+d+e+f) is 11*6 = 66.
So, g = (a+b+c+d+e+f+g) - (a+b+c+d+e+f) = 70-66 = 4
