By looking in a mirror, it appears that it is 3:30 in the clock. Determine the real time at that instant moment?

8:30

The correct answer is Option (4) → 8:30

Step 1: Mirror image time rule

• When a clock shows real time t, its mirror image time is:

$\text{Mirror time} = 12:00 - \text{real time}$

• Or, equivalently:

$\text{Real time} = 12:00 - \text{Mirror time}$

Step 2: Mirror time given

• Mirror image shows 3:30
• Convert 3:30 into minutes: $3 \times 60 + 30 = 210$ minutes

Step 3: Find real time

• Total minutes in 12 hours = 720 minutes

$\text{Real time in minutes} = 720 - 210 = 510 \text{ minutes}$

• Convert 510 minutes back to hours and minutes:

$510 \div 60 = 8 \text{ hours } 30 \text{ minutes}$

So, the real time = 8:30
