As x>8, let's take x as 9. Then y as 19 and z as 10. min value of y+z is 29. It cannot be 24.

E is the answer.

1)x>8.

let x be 8. actual value is greater than 8.

2)y>2x

y>2*8

y=16.

actual value is greater than 16.

3)z>x

z>8.

These are just corner values ......

Adding y + z:

y (min) = 16

z (min) = 8.

y + z ( min) = 24

but actual value must be greater than 24.

Thus, 24 can't be the sum of y +z.

The best answer is E.

From stem y > 2x, and z > x
Adding both we get
y + z >3x------(a)

but x>8
So 3x > 24

from (a) y + z >24

Ans E

Hi,
Its E.
x is greater than 8
y is greater than 16
z is greater than 8
so, y+z = greater than 16 + greater than 8 = greater than 24.
Hence, y+z cannot be 24, which is Option E.

Since x is greater than 8, y is greater than 16, and z is greater than 8. Thus, y + z must be greater than 16 + 8 = 24, so it cannot be 24.
