Question

if 1/2 of A =2/5of B =1/3of C then find A:B:C​

Answer 1

Answer:

If A=1/4 B and B=1/2 C,then find the value of A : B : C.

A) 8:4:1

B) 4:2:1

C) 1:4:8

D) 1:2:4

Correct Answer:

C) 1:4:8

Description for Correct answer:

Given that, A=14B

AB=14 or A:B=1:4

Also,B=12C or BC=12

or B:C=1:2

Now, we have

A:B=1:4; B:C=1:2

A:B:C=(1x1):(1x4):(2x4)

=1:4:8

Answer 2

Answer:

1/2A=2/5B=1/3C

=> A/2=2B/5=C/3

A/2=2B/5

=> A=4B/5

=> A/B=4/5

A : B =4 : 5

again 2B/5=C/3

=> 6B=5C

=> B/C=5/6

=> B : C =5 : 6

A : B = 4 : 5

B : C= 5 : 6

so, A : B : C =4 : 5 : 6
