Question 23. Vaidehi's teacher asks her to find out the average(Arithmetic Mean) of 3 integers x,y and z, given that x
1. (x + y)z = 5
2. (x + z) < 3

Discuss Question

Answer: Option D. -> (E)
:
D
We get two values even on combining both cases.
Case 1: x = -3, y = 4, z = 5 x + z = 2

<

3 x + y + z = 6
Case 2: x = -3, y = -2, z = -1 x + z = -4

<

3 x + y + z = -6
Hence both statements together are also insufficient

eight
nine

eleven

Discuss Question

Answer: Option B. -> nine

Watchman A has worked more shifts in a row than Watchman D; therefore, Watchman A has worked more than eight shifts. The number of Watchman A's shifts plus the number of Watchman B's shifts (five) cannot equal fifteen or more, the number of Watchman C's shifts. Therefore, Watchman A has worked nine shifts in a row (5 + 9 = 14). Therefore, option (b) is the correct answer choice.
