Explanation

"If I were you, I would start looking for another job."

This is a second conditional sentence, used to express a hypothetical situation in the present or future.

In the if clause of a second conditional, we use "were" instead of "was", even with "I" (this is known as the subjunctive mood).

Explanation

"The house was bought from her."

We use "from" to indicate the source or seller in a transaction.

Saying "bought from her" means she was the person who sold the house.

Explanation

"She is going out despite awful weather."

Despite is always written as one word,

While in spite of is always written as three words,

Explanation

 "I am busy right now. I was working on it."

Since "right now" indicates the present moment,

The sentence refers to something happening recently, but is currently interrupted.

The past continuous tense "was working" is the correct choice.

Explanation

Optical disk drives (like CD, DVD, and Blu-ray drives) use laser technology to read and write data on optical discs.

The laser beam detects the pits and lands on the disc surface to interpret data.

Explanation

We are given the equation:

$$7\times ?=4400$$

To find the missing number, divide both sides by 7:

?=4400/7​

Now calculate:

4400/7​=628.5714…

This is not an integer, so none of the options (A) 7, (B) 70, or (C) 4900 are correct.

 Correct answer: (D) None of these

Explanation

Horses have a unique anatomy and a stay apparatus

That allows them to sleep standing up, but they lack the anatomical structure (a proper “down apparatus”) to sit like dogs or cats. 

Explanation

We are given two equations:

Let:

• Cost of one apple = x

• Cost of one orange = y

From the problem:

1. $4x + 2y = 30$
   

2. $$x+3y=15

   
   Step 1: Solve the system of equations

Equation (1):
$4x + 2y = 30$
Divide the whole equation by 2:
→ $2x + y = 15$→ (3)

Equation (2):
$x + 3y = 15$ → (2)

Step 2: Solve equations (2) and (3)

From (3):
$y = 15 - 2x$ → (4)

Substitute (4) into (2):
$x + 3(15 - 2x) = 15$
$x + 45 - 6x = 15$
$-5x+45=15$
$-5x=15-45=-30$
$$x=−30−5=6

Explanation

We are given:

• Product of two numbers = 1320

• HCF (Highest Common Factor) = 6

We are asked to find the LCM (Least Common Multiple).

Key formula:

$$\text{Product of two numbers}=\text{HCF}\times \text{LCM}$$

Substitute values:

$$1320 = 6 times text{LCM}$$LCM=32061​=220

Explanation

 We are given:

• 6 kangaroos eat 6 bags in 6 days

We are asked:
How many kangaroos will eat 100 bags in 100 days?

Step 1: Understand the rate

From the first statement:

6 kangaroos eat 6 bags in 6 days.
So, 1 kangaroo eats 1 bag in 6 days.

Therefore, in 1 day, 1 kangaroo eats 1/6 of a bag.

So, in 100 days, 1 kangaroo eats:

Now, let N be the number of kangaroos needed to eat 100 bags in 100 days.

If each kangaroo eats $frac{100}{6}$/6bags in 100 days, then:
