To find the year 150 years ago, subtract 150 from the current year 2024:

To subtract -10 from -5, you perform the following operation:

−5 − (−10) = −5 + 10 = +5

So, the result is +5.

The correct answer is A: +5.

To find the distance between -7 and +3 on the number line, you calculate the absolute difference between the two numbers:

Distance = ∣ + 3 − (−7)∣ = ∣ + 3 + 7∣ = ∣10∣ = 10 units

So, the distance between -7 and +3 is 10 units.

The correct answer is A: 10 units.

If you started with ₹0, then:

• You deposit ₹50, so your balance becomes ₹50.
• Then, you withdraw ₹70, which results in a negative balance since you have only ₹50.

₹50 − ₹70 = ₹ − 20

So, your new balance is ₹-20.

The correct answer is A: ₹-20.

To subtract +4 from -3, you perform the following operation:

−3 − (+4) = −3 − 4 = −7

So, the correct result is -7.

The correct answer is B: -7.

If you start at Floor +2 and move 4 floors down, you subtract 4 from +2:

+2 − 4 = −2

So, you will end up at Floor -2.

The correct answer is A: Floor -2.
