Explanation

The correct answer is: She asked me if I was happy in my new job.

This is because when converting direct speech to indirect speech, the present tense "are" becomes the past tense "was".

The correct indirect speech sentence is a polite and grammatically correct way to report the question.

Explanation

1. Average income of A and B is 50000, so their total income is:

2 x 50000 = 100000

2. Average income of B and C is 60000, so their total income is:

2 x 60000 = 120000

3. Average income of A and C is 55000, so their total income is:

2 x 55000 = 110000
Now, let's analyze the situation:

- A's income + B's income = 100000 ... (1)

- B's income + C's income = 120000 ... (2)

- A's income + C's income = 110000 ... (3)

We can add (1) and (3), and subtract (2) from the result:
(100000 + 110000) - 120000 = 90000
Simplifying this, we get:
190000 - 120000 = 70000
Now, divide by 2:
70000 / 2 = 35000
Now, add B's income and C's income (equation 2):
35000 + C's income = 120000
Subtract 35000 from both sides:
C's income = 85000
Now, subtract C's income from equation (3):
A's income + 85000 = 110000
Subtract 85000 from both sides:
A's income = 25000
Now, subtract A's income from equation (1):
25000 + B's income = 100000
Subtract 25000 from both sides:
B's income = 75000 - 25000
B's income = 55000
So, B's income is 55000.

Explanation

Convert the speed of the train from km/hr to m/s:

45 km/hr = 45 × 1000 m / 3600 s = 12.5 m/s

The train crosses the bridge in 30 seconds, so the total distance covered is the length of the train plus the length of the bridge. Let's call the length of the bridge "x". Then, the total distance = 130 m (train length) + x.

Since the train crosses the bridge in 30 seconds, we can use the formula:

Distance = Speed × Time

Substitute the values:

130 m + x = 12.5 m/s × 30 s

Simplify the equation:

130 m + x = 375 m

Subtract 130 m from both sides:

x = 245 m

So, the length of the bridge is 245 m.
