Answer» If A : B = 3 : 4, B : C = 5 : 7 and C : D = 8 : 9 then A : D is equal to[A]10 : 21[B]21 : 10[C]3 : 7[D]7 : 3 10 : 21 Hence option [A] is the right answer. A/D = A/B × B/C × C/D = 3/4 × 5/7 ×8/9 = 1/1 × 5/7 × 2/3 = 5×2/7×3 = 10/21 = 10:21Hence option D) 10:21 is the correct answer . 10:21 is the right answer. plz like my answer

Answer»

If A : B = 3 : 4, B : C = 5 : 7 and C : D = 8 : 9 then A : D is equal to[A]10 : 21[B]21 : 10[C]3 : 7[D]7 : 3

10 : 21

Hence option [A] is the right answer.

A/D = A/B × B/C × C/D = 3/4 × 5/7 ×8/9 = 1/1 × 5/7 × 2/3 = 5×2/7×3 = 10/21 = 10:21Hence option D) 10:21 is the correct answer .

10:21 is the right answer.
