In a particular year a company produced 8765435 bicycles. Next year, the number of bicycles produced was 1378689 more than those produced in the preceding year.
How many bicycles were produced during the second year ?
How many bicycles were produced during these two years ?

Answer

To solve the problem step by step, we will follow these steps:

### Step 1: Identify the number of bicycles produced in the first year.
The company produced **8,765,435 bicycles** in the first year.

### Step 2: Identify the increase in production for the second year.
The number of bicycles produced in the second year is **1,378,689 more** than those produced in the first year.

### Step 3: Calculate the number of bicycles produced in the second year.
To find the total number of bicycles produced in the second year, we need to add the number of bicycles produced in the first year to the increase in production.

\[ \text{Bicycles produced in the second year} = \text{Bicycles in the first year} + \text{Increase} \]

\[ \text{Bicycles produced in the second year} = 8,765,435 + 1,378,689 \]

Now, we will perform the addition step by step:

- **Units place:** 5 + 9 = 14 (write 4, carry 1)
- **Tens place:** 3 + 8 + 1 (carry) = 12 (write 2, carry 1)
- **Hundreds place:** 4 + 6 + 1 (carry) = 11 (write 1, carry 1)
- **Thousands place:** 5 + 7 + 1 (carry) = 13 (write 3, carry 1)
- **Ten thousands place:** 6 + 3 + 1 (carry) = 10 (write 0, carry 1)
- **Lakh place:** 7 + 1 + 1 (carry) = 9 (write 9)
- **Ten lakh place:** 8 + 0 + 0 (carry) = 8 (write 8)

So, the total number of bicycles produced in the second year is **10,144,124**.

### Step 4: Calculate the total number of bicycles produced in both years.
To find the total production over the two years, we will add the number of bicycles produced in the first year to the number produced in the second year:

\[ \text{Total bicycles produced} = \text{Bicycles in the first year} + \text{Bicycles in the second year} \]

\[ \text{Total bicycles produced} = 8,765,435 + 10,144,124 \]

Now, we will perform this addition step by step:

- **Units place:** 5 + 4 = 9
- **Tens place:** 3 + 2 = 5
- **Hundreds place:** 4 + 1 = 5
- **Thousands place:** 5 + 4 = 9
- **Ten thousands place:** 6 + 1 = 7
- **Lakh place:** 7 + 0 = 7
- **Ten lakh place:** 8 + 1 = 9

So, the total number of bicycles produced in both years is **18,909,559**.

### Final Answers:
- Bicycles produced in the second year: **10,144,124**
- Total bicycles produced in both years: **18,909,559**
