Question

if a number is divided into three parts which are in the ratio 1:1:2 then what percentage of the total value is the sum of the equal parts?​

Answer 1

Answer:

Let the number be 4x .

three parts will be = x, x , 2x (1:1:2)

sum of equal parts now = x + x = 2x

% out of total will be = 2x*100/4x = 50% (Ans.)

Answer 2

50% of the total value is the sum of the equal parts.

Step-by-step explanation:

If a number is divided into three parts which are in the ratio 1:1:2

Let three number be,

First number = 1x

Second number = 1x

Third number = 2x

Sum of all three number = 1x+1x+2x = 4x

Sum of equal part number = 1x + 1x = 2x

Percentage of equal part numbers $=\dfrac{\text{Sum of equal part numbers}}{\text{Sum of all numbers}}$

$\text{Percentage of equal part numbers}=\dfrac{2x}{4x}\times 100$

$\text{Percentage of equal part number}=50\%$
