(i) |X|-|Z| (ii) ||Y|-|Z||
(iii) |X| + |Y|

A

(i) 16 (ii) 9 (iii) 40

B

(i) 16 (ii) 8 (iii) 41

C

(i) -16 (ii) 8 (iii) 40

D

(i)-15 (ii) 9 (iii) 40

Text Solution

Verified by Experts

The correct Answer is:
(i) -16 (ii) 8 (iii) 40
X = -16
Y = -24
Z = +32
(i) |X|-|Z|
= |-16| - |32| = 16-32 = -16
(ii) |Y|-|Z|
= |-24|-|32| = 24-32 = -8
`rArr ||Y|-|Z||=|-8| = 8`
(iii) |X| + |Y|
= |-16| + |-24| = 16 + 24 = 40
