If `a/b=b/c=c/d ,\ t h e n(b^3+c^3+d^3)/(a^3+b^3+c^3)` will be equal to `a/b` b. `b/c` c. `c/d` d. `d/a`

If (a)/(b)=(b)/(c)=(c)/(d), then (b^(3)+c^(3)+d^(3))/(a^(3)+b^(3)+c^(3)) will be equal to (a)/(b) b.(b)/(c) c.(c)/(d) d.(d)/(a)

If a/b = b/c = c/d , then show that (a - b)^(3) : (b - c)^(3) = a : d .

a=2b=3c=4d then a:b:c:d is

If (a)/(b)=(c)/(d)=(e)/(f) , then (a^(3)+c^(3)+e^(3))/(b^(3)+d^(3)+f^(3))=_____

If a-b:b-c:c-d=1:2:3 then (a+d):c=

If a/b=b/c=c/d=d/e=e/f=1/3 , find the value of ((a+b+c+d+e)/(b+c+d+e+f)):

If (cosx)/a=(cos(x+theta))/b=(cos(x+20))/c=(cos(x+3theta))/d then (a+c)/(b+d) is equal to (a) a/d (b) c/b (c) b/c (d) d/a

If (cosx)/a=(cos(x+theta))/b=(cos(x+20))/c=(cos(x+3theta))/d then (a+c)/(b+d) is equal to (a) a/d (b) c/b (c) b/c (d) d/a

If (cosx)/a=(cos(x+theta))/b=(cos(x+2theta))/c=(cos(x+3theta))/d then (a+c)/(b+d) is equal to (a) a/d (b) c/b (c) b/c (d) d/a
