Explanation

A dead body does not maintain a fixed temperature — it cools down to match the ambient (surrounding) temperature over time.

This process is called algor mortis, and the body typically loses about 1.5°C per hour after death until it reaches room temperature.

Explanation

Tense: Present Perfect (have built) → Passive: has been built

Active voice: The engineers have built a perfect dam across the stream.

Passive voice: A perfect dam across the stream has been built by the engineers.

"A perfect dam" is singular → has.

Explanation

Based on the analysis:

The key factor that stands out is symmetry:

•  E and F have vertical symmetry.
•  Z has rotational symmetry.
•  K has no symmetry.

Given this, K is the least like the others because it's the only one without any form of symmetry.

Explanation

Income on the first day = Re. 1.
Income on the 2nd day = Rs. (1x2) = Rs. 21.
Income on the 3rd day = Rs. (21 x 2) = Rs. 22 and so on. Thus, Income on the rath day = Rs. 2n-1.
Therefore Income on the 10th day = Rs. 29.

Explanation

The preposition "at" is used to indicate a specific time (e.g., at 7:30).

Phrases like "half past seven" always take "at" before them when referring to time.

Explanation

Let's assume Aslam purchased x bananas and y oranges.

The total cost is 8x + 7y = 30.

We need to find a combination of x and y that satisfies the equation.

If x = 2 and y = 2:

8(2) + 7(2) = 16 + 14 = 30

This combination works, so Aslam purchased 2 bananas and 2 oranges.

Explanation

Let's break it down:

2 typists can type 2 pages in 5 minutes, so:

2 typists can type 4 pages in 10 minutes.

To type 20 pages in 10 minutes, we'll need:

20 pages / 4 pages = 5 times more typists

Since 2 typists can type 4 pages, we'll need:

2 typists × 5 = 10 typists
