Explanation

To find the total strength now, you need to calculate 12% of the original strength and add it to the original strength.

Original strength = 550

Increase = 12% of 550 = (12/100) × 550 = 66

New strength = Original strength + Increase = 550 + 66 = 616

So, the total strength now is 616.

Explanation

Vincent van Gogh (1853-1890) was a Dutch post-impressionist painter.

He is famous for his bold and expressive works, such as "Sunflowers", "The Starry Night", and "Self-Portrait with Bandaged Ear".

Explanation

Four years ago, the average age of A, B, and C was 25 years.

This means that the total age of A, B, and C four years ago was 25 x 3 = 75 years.

Since then, all three have aged 4 years, so their total age now is 75 + 4 + 4 + 4 = 87 years.

Five years ago, the average age of B and C was 20 years.

This means that the total age of B and C five years ago was 20 x 2 = 40 years.

Since then, both B and C have aged 5 years, so their total age now is 40 + 5 + 5 = 50 years.

Now, we know that the total age of A, B, and C is 87 years, and the total age of B and C is 50 years.

So, A's current age is 87 - 50 = 37 years.

The correct answer is: 37 years

Explanation

Free software and Open-source software are often used interchangeably, but they have slightly different meanings:

• Free software refers to software that is distributed free of cost, and the user has the freedom to use, modify, and distribute it.
• Open-source software refers to software whose source code is made available publicly, allowing users to view, modify, and distribute the software.

Explanation

To solve this proportion, we can use the following steps:

Write the proportion as a fraction: 3/x = 12/20

Cross-multiply: 3 × 20 = 12 × x

Simplify: 60 = 12x

Divide both sides by 12: x = 60/12

Simplify: x = 5

So, the value of x is 5.

Explanation

When a computer detects invalid data, it often displays a red triangle or an error indicator to alert the user.

This symbol is commonly used in spreadsheets, databases, and other software applications to indicate that the data is incorrect, inconsistent, or outside of the expected range.

Explanation

1 meter (m) = 1000 millimeters (mm)

1 meter (m) = 100 centimeters (cm)

1 centimeter (cm) = 10 millimeters (mm)

1 millimeter (mm) = 0.1 centimeters (cm)

1 kilometer (km) = 1000 meters (m)

Explanation

Five years ago, the average age of P and Q was 15 years.

This means that the total age of P and Q five years ago was 15 x 2 = 30 years.

Since then, both P and Q have aged 5 years, so their total age now is 30 + 5 + 5 = 40 years.

The average age of P, Q, and R today is 20 years, so the total age of P, Q, and R is 20 x 3 = 60 years.

We already know that the total age of P and Q is 40 years, so R's age must be 60 - 40 = 20 years.

After 10 years, R's age will be 20 + 10 = 30 years.

So, the correct answer is: 30 years

Explanation

آپ ہمیشہ ظاہری شکل میں نہیں جا سکتے۔

The correct phrase is "go by appearances," meaning to judge something based solely on how it looks.

It suggests that looks can be deceiving and shouldn't always be trusted.
