11. The present ages of A,B and C are in the ratio of 8:14: 22 respectively. the present ages of B,C and D are in the ratio of 21:33:44 respectively. which of the following represents the ratio of the present ages of A,B,C, and D respectively ?
A) 12:21:33:44 B) 12:2281:44 C) 12:21:36:44 D) cannot be determined​

Answer 1

Answer:

D

Step-by-step explanation:

Let the present age of A B C be 8x 14x 22x

then-

Let the present age of B C D be 21x 33x 44x

then

present age of B = 14X = 21x

then

14x = 21x

14x-21x = 0

-7x = 0

x =0/-7 ( that cannot be determined)

So the answer is D) cannot be determined

Answer 2

Answer:

(A) 12:21:33:44

Step-by-step explanation:

A : B : C = 8 : 14 : 22 or 4 : 7 : 11 = 12 : 21 : 33

B : C : D = 21 : 33 : 44

Therefore, A : B : C : D

= 12 : 21 : 33 : 44
