Question

a:2=b:5=c:8 then 50% of a = 20% of b = x % of c. find x

Answer 1

Answer:

x = 30 , because "A" has 50% and "B" has 20% , remaining percentage is 30% , 50 + 20 + 30 = 100 %

if A has 50%

  B has 20% Then

   C should has 30%

Step-by-step explanation:

Answer 2

The value of x is 12.5.

Step-by-step explanation:

Since we have given that

a:2=b:5=c:8

So, it becomes,

$\dfrac{a}{2}=\dfrac{b}{5}=\dfrac{c}{8}\\\\a:b:c=2:5:8$

Now,

50% of a = 20% of b = x % of c

Mathematically, it is expressed as

$\dfrac{50}{100}a=\dfrac{20}{100}b=\dfrac{x}{100}c\\\\\dfrac{a}{2}=\dfrac{b}{5}=\dfrac{cx}{100}\\\\\text{it will be compared to }\\\\\dfrac{a}{2}=\dfrac{b}{5}=\dfrac{c}{8}\\\\So,\ it\ becomes\\\\\dfrac{c}{8}=\dfrac{cx}{100}\\\\x=\dfrac{100}{8}\\\\x=12.5$

Hence, the value of x is 12.5.
