Question : 35 of 100

Marks: +1, -0

If 60% of A = 30% of B, B = 40% of C, C = x% of A, then value of x is

Solution:

(2) According to the question,

{60 {A}}/{100}= {3 0 { B}}/{100}

⇒

{3 {A}}/{5}= {3 {B}}/{10}= {3}/{10} ×{40}/{100} {C}

⇒

{3 {A}}/{5}= {3 {C}}/{25}= {3}/{25} ×{A} ×{x}/{100}

⇒{3}/{5}= {3 x}/{2500}

⇒ 5 x=2500

⇒ x= {2500}/{5}=500
