Question

w = (-3) . (-9), x = 3 + (-9),y = -3 x 9 , z = -3 + 9. If these are arranged in decreasing order of values, the correct sequence would be *
1)w, z, x, y
2)w, y, z, x
3)z, x, y, w
4)w, z, y, x

Answer 1

Answer:

Option – ( a ) is correct

Step-by-step explanation:

W = ( –3 ) * ( –9 ) = 27

X = 3 + ( –9 ) = 3 – 9 = –6

Y = ( –3 * 9 ) = –27

Z = ( –3 + 9 ) = 6

Clearly ,

$27 > 6 > - 6 > - 27$

Hence , correct sequence would be :

$w > z > x > y$
