If a : b = 2 : 3 , b: c = 2 : 4, then a : b : c = ?

If a : b = 3 : 2 and b : c = 4 : 5 , find a : c

(a) If A : B = 3 : 4 and B : C = 6 : 7 , find : (i) A : B : C (ii) A : C (b) If A : B = 2 : 5 and A : C = 3 : 4 , find : A : B : C .

If a : b=4:5\ a n d\ b : c=2:3, then a : c=\ .................

If a:b:c=2:3:4, find a,b and c

If a ,b and c are in A.P. and b-a ,c-b and a are in G.P., then a : b : c is (a). 1:2:3 (b). 1:3:5 (c). 2:3:4 (d). 1:2:4

If 2a + 3b -c =a + 2b + c =3a -b - c then what is the ratio of a:b:c?

If |b+c c+a a+b a+b b+c c+a c+a a+b b+c|=k|ab c c a b b c a| , then value of k is 1 b. 2 c. 3 d. 4

If a+b+c=0 and a^2+b^2+c^2=1, then (a) a b+b c+c a=1/2 (b) a b+b c+c a=-1/2 (c) a^4+b^4+c^4=1/2 (d) a^4+b^4+c^4=3/2

In a A B C ,A : B : C=3:5: 4. Then a+b+csqrt(2) is equal to a. 2b b. 2c c. 3b d. 3a

If a ,b ,a n dc are in H.P., then th value of ((a c+a b-b c)(a b+b c-a c))/((a b c)^2) is ((a+c)(3a-c))/(4a^2c^2) b. 2/(b c)-1/(b^2) c. 2/(b c)-1/(a^2) d. ((a-c)(3a+c))/(4a^2c^2)
