12 p.m.−2 hours=10 p.m.

April has 30 days. Number of hours in April =30×24=720 hours

To find out how many months there are in 4 years 3 months, let's break it down:

1. Number of months in 1 year = 12 months
2. Number of months in 4 years = 4×12 = 48 months
3. Additional months = 3 months

So, the total number of months is:

48 months + 3 months = 51 months

Answer: c) 51

• A standard year has 365 days.
• Dividing 365 days by 7 (days per week) gives 52 full weeks with one extra day.
• This means there are exactly 52 complete weeks in a year.

10 minutes after 5:55 p.m. will be 6:05 p.m.

No. of hours of work per day = 6 hours 30 minutes
No. of hours of work for 5 days = 6 hours 30 minutes × 5 = 30 hours
150 minutes 60 minutes = 1 hour
∴150 minutes = 2 hours 30 minutes
∴ 30 hours 150 minutes = 30 hours + 2 hours 30 minutes = 32 hours 30 minutes

A quarter hour means 15 minutes.

2.5 hours means 2 hours and half an hour.
2 hours = 120 minutes
Half an hour = 30 minutes
So total = 120 + 30 = 150 minutes

Now see how many 15 minutes fit in 150 minutes:
150 ÷ 15 = 10

So the answer is 10 quarter hours.

So, Correct Option: B
