If India’s population is increasing at the rate of 13.6 million per year, then what percentage of total increase in world’s population in one calendar year is contributed by the Indians

Options

A. 0.1
B. 0.17
C. 0.15
D. 0.2

Explanation

To solve the problem of determining what percentage of the total increase in the world's population is contributed by India's population increase, we can follow these steps:

### Step 1: Determine the total increase in the world's population.
The world's population is approximately 7.7 billion. To find the total increase in the world's population per year, we need to calculate 1% of 7.7 billion.

\[ \text{Total increase in world population} = 1\% \text{ of } 7.7 \text{ billion} \]
\[ = \frac{1}{100} \times 7.7 \text{ billion} = 0.077 \text{ billion} = 77 \text{ million} \]

### Step 2: Identify India's population increase.
According to the problem, India's population is increasing at the rate of 13.6 million per year.

### Step 3: Calculate the percentage contribution of India's population increase to the world's total increase.
To find the percentage of the total increase in the world's population contributed by India's increase, we can use the formula:

\[ \text{Percentage contribution} = \left( \frac{\text{India's population increase}}{\text{Total world population increase}} \right) \times 100 \]

Substituting the values we have:

\[ \text{Percentage contribution} = \left( \frac{13.6 \text{ million}}{77 \text{ million}} \right) \times 100 \]

Calculating this gives:

\[ \text{Percentage contribution} = \left( \frac{13.6}{77} \right) \times 100 \approx 17.68\% \]

### Step 4: Conclusion
Thus, India's population increase contributes approximately 17.68% to the total increase in the world's population in one calendar year.
