Question

A clock seen on a mirror shows quarter to three. What is the correct time shown by the clock ?

Answer 1

Answer:

9: 15

Explanation:

quarter in clock = 60 * 1/4 = 15.

Quarter to 3 means, it needs 15 more minutes to become 3.

The reflected time is 2:45.

Hence the actual time will be 9:15

Answer 2

The correct time is 9 : 15

• Quarter to 3 means 15 minutes left to 3 , i.e. 2:45 (that too observed in a mirror).

Now, we know the concept of LATERAL INVERSION in a plane mirror.

So, the object clock will show 15 minutes passed after 9 'o' clock ( because 9 is placed opposite to 3)

So, the time will be :

Quarter passed 9 (i.e. 9:15)
