Explanation

Four people live in a house.

There are 22 houses in one street.

To find the total number of people living in the street, multiply the number of people per house by the number of houses:

4 people/house × 22 houses = 88 people

So, 88 people live in the street.

Explanation

The sentence should read: "This is the oldest tree in the forest."

The word "elder" is often confused with "oldest", but they have slightly different meanings:

• "Elder" typically refers to someone or something that is older than others, but not necessarily the oldest.
• "Oldest" refers to someone or something that is the most ancient or has been around the longest.

Explanation

To find the number of lawns completed in 10 hours, we can set up a proportion:

2 hours / 3 lawns = 10 hours / x lawns

We can then cross-multiply and solve for x:

2x = 3 × 10

2x = 30

x = 30/2

x = 15

So, in 10 hours, 15 lawns will be completed.

Explanation

The Von Thünen model explains agricultural land use patterns based on distance from a central market.

Johann Heinrich von Thünen developed it, and it was first published in 1826.

Explanation

To find the smallest ratio, we need to simplify the fraction 0.35/0.65.

First, convert the decimals to fractions:

0.35 = 35/100 = 7/20

0.65 = 65/100 = 13/20

Now, divide the fractions:

(7/20) ÷ (13/20) = 7/13

So, the smallest ratio is 7/13.

Explanation

If 2/3 of the men do not attend the mess, that means only 1/3 of the men are attending the mess.

Since the provision is for 30 days for the entire group, the food will now last three times as long, since only one-third of the group is consuming it.

So, the food will last for 30 x 3 = 90 days.

Explanation

To find |f(1)|, we need to evaluate the function f(x) = -3(x^2) - 2(x) + 1 at x = 1.

f(1) = -3(1^2) - 2(1) + 1

= -3(1) - 2(1) + 1

= -3 - 2 + 1

= -4

Now, we need to find the absolute value of f(1):

|f(1)| = |-4| = 4

Explanation

To find the original price, we need to remove the GST amount from the inclusive price.

Price including GST = Rs. 945

GST percentage = 5%

First, convert the GST percentage to a decimal: 5% = 0.05

Then, divide the price including GST by (1 + GST decimal):

Rs. 945 ÷ (1 + 0.05) = Rs. 945 ÷ 1.05 = Rs. 900

Explanation

To calculate the percentage of discount, you can use the following formula:

percentage discount = (original price – new price) / original price * 100%

In this case, the original price is 0.62 and the new price is 0.42. So, the calculation would be:

percentage discount = (0.62 – 0.42) / 0.62 * 100% = 0.2 / 0.62 * 100% = 0.3225806452 * 100% = 32.26% ~= 32%

Therefore, the actual percentage of discount is 32%.
