Question

please answer these two question

Answer 1

(1) 16% of A = 20% of B

16A/ 100 = 20B/ 100

16A = 20B

A/ B = 20 / 16 = 5/ 4


A : B = 5 : 4

(ii) A = 1/ 3 *B ---(1) B = 1/ 2*C ---(2)

from (2) B = C/ 2

from (1) A = 1/ 3*B = 1/ 3 * (C / 2)

A = C / 6

A : B : C = C/ 6 : C/ 2 : C

A : B : C = 1/ 6 : 1/ 2 : 1

L.C. M (6 , 2 ,1) = 6

thus

A : B : C = 1×6/ 6 : 1×6/ 2 : 1× 6

= 1 : 3 : 6

Answer: A : B : C = 1 : 3 : 6

Answer 2

First answer

16A/100= 20B/100

16A=20B

A/B= 20/16= 5/4= 5:4
