Question

Match List I with List II : | List I | List II | |---|---| | A. If $4a = 5b$ and $7b = 9c$, then $a : b : c$ is equal to | I. $7 : 9 : 11$ | | B. If $A = 1/4 B$ and $B = 1/2 C$, then $A : B : C$ is equal to | II. $45 : 36 : 28$ | | C. If $P : Q : R = 2 : 3 : 4$, then $P/Q : Q/R : R/P$ is equal to | III. $1 : 4 : 8$ | | D. If $a/7 = b/9 = c/11$, then $a : b : c$ is equal to | IV. $8 : 9 : 24$ | Choose the correct answer from the options given below :

Accepted Answer

D. A: $a/b = 5/4 = 45/36$ and $b/c = 9/7 = 36/28 \implies a:b:c = 45:36:28$ (II). B: $A:B = 1:4$ and $B:C = 1:2 = 4:8 \implies A:B:C = 1:4:8$ (III). C: $P/Q : Q/R : R/P = 2/3 : 3/4 : 4/2 = 8 : 9 : 24$ (IV). D: $a:b:c = 7:9:11$ (I).

Explanation

Practise this under exam conditions

List I	List II
A. If $4a = 5b$ and $7b = 9c$ , then $a : b : c$ is equal to	I. $7 : 9 : 11$
B. If $A = 1/4 B$ and $B = 1/2 C$ , then $A : B : C$ is equal to	II. $45 : 36 : 28$
C. If $P : Q : R = 2 : 3 : 4$ , then $P/Q : Q/R : R/P$ is equal to	III. $1 : 4 : 8$
D. If $a/7 = b/9 = c/11$ , then $a : b : c$ is equal to	IV. $8 : 9 : 24$
