If a,b,c,d are positive real numbers such that `(a)/(3) = (a+b)/(4)= (a+b+c)/(5) = (a+b+c+d)/(6)`, then `(a)/(b+2c+3d)` is:-

If a, b, c are distinct positive real numbers such that a+(1)/(b)=4,b+(1)/( c )=1,c+(1)/(d)=4 and d+(1)/(a)=1 , then

If a, b, c are distinct positive real numbers such that a+(1)/(b)=4,b+(1)/( c )=1,c+(1)/(d)=4 and d+(1)/(a)=1 , then

If a,b,c,d are positive real numbers such that a+b+c +d = 12 , then M = ( a+ b ) ( c + d ) satisfies the relation :

If a,b,c,d are positive real number such that a+b+c+d=2 , then M=(a+b)(c+d) satisfies the relation:

If a,b,c,d,e are positive real numbers such that,a+b+c+d+e=15 and ab^(2)c^(3)d^(4)e^(5)=(120)^(3).50 then the value of a^(2)+b^(2)+c^(2)+d^(2)+e^(2) is

If a,b,c,d are four positive numbers that (i)((a)/(b)+(b)/(c))((c)/(d)+(d)/(e)) =4.sqrt((a)/(c))(iii)(a)/(b)+(b)/(c)+(c)/(d)+(d)/(e)+(e)/(a) =(1)/(5)

If a, b, c and d are four positive real numbers such that sum of a, b and c is even the sum of b,c and d is odd, then a^2-d^2 is necessarily

If a,b,c,d are positive real number with a+b+c+d=2, then M=(a+b)(c+d) satisfies the inequality
