Explanation

0 (since the square of a prime number is not prime)

A prime number is a positive integer greater than 1 that has no positive divisors other than 1 and itself.

The square of a prime number is not prime because it has at least three divisors: 1, the prime number, and the square itself.

Explanation

In this case, the initial investment is Rs 80,000, and the discounted cash inflows are Rs 30,000 per year for three years.

To find the IRR, we can use trial and error or a financial calculator or spreadsheet. 

 if we use a discount rate of 15%,

we can calculate the present value of the cash inflows as follows:

Year 1: Rs 30,000 / (1 + 0.15)^1 = Rs 26,086.96

Year 2: Rs 30,000 / (1 + 0.15)^2 = Rs 22,730.18

Year 3: Rs 30,000 / (1 + 0.15)^3 = Rs 19,756.67

Now, we can calculate the present value of the cash inflows and check if it equals the initial investment:

Present value of cash inflows = Rs 26,086.96 + Rs 22,730.18 + Rs 19,756.67 = Rs 68,573.81

Since the present value of the cash inflows is less than the initial investment,

we need to try a higher discount rate.

By trying different discount rates, we find that a discount rate of 20% makes the present value of the cash inflows equal to the initial investment of Rs 80,000.

Therefore, the IRR of the project is 20%.

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

Explanation

14 ---- 400 x ----- 600 ___________ Using BCM

we have, 14*600 = 400*x

Solving the equation, we have 8400/400 = x

So, 21 = x,

Or, x = 21

Explanation

A trade surplus occurs when a country exports more goods and services than it imports.

This indicates a positive balance of trade, where the country earns more revenue from exports than it spends on imports.

Explanation

The mean of 5 observations is 10.

This means the sum of the 5 observations is:

$$\text{Sum of 5 observations}=\text{Mean}\times \text{Number of observations}=10\times 5=50$$

Now, a new observation (10) is added. The new sum becomes:

$$\text{New sum}=50+10=60$$

The new mean of the 6 observations is:

New mean=New sum/Number of observations

​=660​

=10

Explanation

A contract is a type of legally binding written or spoken agreement.

A valid contract will create a mutual obligation.

This means that each of the parties is obligated, or required, to perform a duty under the contract.

The contract conditions determine the parties' obligations.

Explanation

An Irrational Number is a real number that cannot be written as a simple fraction: 1.5 is rational,

but π is irrational.

Explanation

(105 - x) + x + (134 - x) = 200

239 - x = 200

x = 39

Only burger = 134 - 39

= 95
