Question

if sum of X+Y+Z is 100,
value of Y is 2X
Value of Z is 20 less on 2X
what is the value of X ?

Answer 1

Answer:

X=24

Explanation:

According to the question,

Let x be x

Let y be 2x

Let z be 2x-20

x+y+z=100

Substitute the values given above in the equation,

x+2x+2x-20=100

5x-20=100

5x=100+20

5x=120

x=120/5

x=24

To check,

Substitute the x value,

24+48+28=100

Hence, the value of x=24.
