Explanation

2/7 = (2/7) x (100/100) = 200/7 = 28.57%

1/35 = (1/35) x (100/100) = 100/35 = 2.86%

Now, divide the percentage equivalent of 1/35 by the percentage equivalent of 2/7 and multiply by 100:

(2.86 ÷ 28.57) x 100 = 10%

So, 1/35 is 10% of 2/7.

The correct answer is: 10%

Explanation

To find the percentage that 1.14 is of 190, you can use the formula:

Percentage=(  1.14/190 )×100≈0.6%

This means that 1.14 is approximately 0.6% of 190.

Explanation

If we add a constant (such as 3) to each observation of a data set, the mean will be increased by 3

This is because adding the same constant to each data point shifts the entire data set by that constant value, including the mean.

Explanation

Each pair of shoes consists of 2 shoes, so 100 pairs of shoes equals:

$$100\times 2=200\text{ shoes}$$

Each case holds 20 shoes, so to find how many cases are needed:

200/20 ​=10 cases

Explanation

To calculate 150% of 300,000, use the formula:

150%×300,000=1.5×300,000=450,000

Thus, 150% of 300,000 is 450,000.

Explanation

Given: p/q = 7

We can rewrite this as: p = 7q

Now, let's evaluate the expression: p+q/p-q

Substitute p = 7q: (7q+q)/(7q-q)

Combine like terms: (8q)/(6q)

Simplify: 8/6

Divide both numerator and denominator by 2: 4/3

So, the correct answer is: 4/3

Explanation

Pictograms use symbols or images to represent data in a way that shows the frequency or count of items.

Each symbol or image represents a specific quantity, making it easy to visualize and compare counts.

Explanation

Note: The answer given in the FPSC answer key is (c) but the actual answer is (b).

A rudder is a steering device used in boats and ships.

Birds do not have rudders.

They use their wings and tail feathers for steering and balance.

Explanation

To evaluate the expression 2^2n + 1, we need to follow the order of operations (PEMDAS):

Calculate the exponent: 2^2n = 2^(2*3) = 2^6

Calculate the value of 2^6: 2^6 = 64

Add 1 to the result: 64 + 1 = 65

Therefore, the correct answer is: 65

Explanation

Let's break this down step by step:

1. Let the man's monthly income be x.
2. He spends Rs. 3500 per month, which means his savings are x - 3500.
3. He saves 12 ½% of his income, which can be written as a decimal: 0.125x.
4. Since his savings are equal to his income minus his expenses, we can set up the equation: 0.125x = x - 3500.
5. Simplify the equation: 0.125x = x - 3500 --> 0.125x - x = -3500 --> -0.875x = -3500.
6. Divide both sides by -0.875: x = 3500 / 0.875 --> x = 4000.

So, the man's monthly income is Rs. 4000.
