If `x, y, z` are positive numbers in A.P., then

If x, y, z are distinct positive real numbers is A.P. then (1)/(sqrt(x)+sqrt(y)), (1)/(sqrt(z)+sqrt(x)), (1)/(sqrt(y)+sqrt(z)) are in

If x, y, z are distinct positive real numbers is A.P. then (1)/(sqrt(x)+sqrt(y)), (1)/(sqrt(z)+sqrt(x)), (1)/(sqrt(y)+sqrt(z)) are in

If x,y,z are three natural numbers in A.P. such that x+y+z=30 , then the possible number of ordered triplet (x, y, z) is :

IF x,2y,3z are in A.P. where x,y,z are unequal number in a G.P., then the common ratio of this G.P. is (a) 3 (b) 1/3 (c) 2 (d) 1/2

Let x,y and z are three positive numbers and P=(x+y+z)/(2); if (p-x):(p-y):(p-z)=3:5:7 then the ratio of x:y:z is

If a, x, y, z, b are in A.P., then value of xyz is 35/3 and if a, x, y, z, b are in H.P., then value of xyz is 75/7, where a and b are given positive integers. Then value of (ab) is

If x,2y, 3z are in A.P. where the distinct numbers x,y,z are in G.P., then the common ratio of the G.P. is :
