=160000:100

= 1600

Explanation

The rule says Audit must come after Legal, but Admin can appear anywhere in the sequence.

Admin - Legal - Audit follows this rule correctly, making it a valid sequence.

Explanation

The statement says "All efficient typists are good organizers," meaning every efficient typist is included in the group of good organizers.

So it's logically valid to say that some efficient typists are good organizers (since “all” includes “some”).

Explanation

With parallelization across different staff, the tasks can be efficiently pipelined.

Given the schedule:

1. Typist takes 2 hours per document.

2. Proofreader takes 1 hour per document.

3. Signer takes 0.5 hours per document.

The pipeline schedule shows:

After Doc 1 is typed (2 hours), it moves to proofreading, and Doc 2 starts typing.

By the time Doc 3 is done typing (6 hours total for typing 3 documents), Doc 1 would have been signed (3.5 hours total for Doc 1 to be signed after starting typing).

The critical path here is determined by the longest sequence in the pipeline, which is typing (6 hours for 3 documents).

Given the pipelined schedule provided:

The last document (Doc 3) finishes signing at 4.5 hours.

Explanation

There are three on-off switches on a control panel A, B, and C. They have to be changed from the initial setting to a second setting according to the following conditions:

1. In case switches A and B are the only switches on in the initial setting, then turn on switch C.
2. In case all three switches are on the initial setting, then turn off the switch C.
3. For any other initial setting, turn on all switches that are off and turn off all switches, if any, that are on.

Question:

In case all three switches are on in the second setting, which among the following could be the initial setting?

A) A on, B on, C on.

B) A on, B on, C off.

C) A on, B off, C on.

D) A on, B off, C off.

E)  A off, B on, C off.

Explanation

The possible number of subsets of a set with $n$ elements, including the empty set and the universal set, is $2^n$.

Explanation

Statement i- It was raining cats and dogs

Statement ii- The football match was cancelled

A) Statement (i) is the case and statement (ii) is its effect

B) Statement (ii) is the case and statement (i) is its effect

C) Both the statement (i) and (ii) are independent 

D) Both the statement (i) and (ii) are effect of indepentent causes

Explanation

Two find the two terms from a sum of two consecutive odd integers

Let the first term be, n

Then the next consecutive odd number is. n + 2

So the two terms sum to n + n +2 = 16

so 2n + 2 =16

Subtract 2 from both sides

2n = 14

Divide both sides by 2

n = 7 which is the first term

and n + 2 = 7 '

7 +2 = 9 is the second term
