Step-by-step explanation:

Minutes between noon and 9 am is 180 min.

So take 9am as 0 and noon as 180.

Then we have 2 equations

x + t = 180

and

x - 44 = 7t

Solving these two, we get x = 163min i.e. 2hr 43 min.

So adding 163 to 9 am we will have 11:43am.

Answer:

The present time is 11 : 43 AM

Given:

After t minutes , time will be 12 AM

44 minutes ago , time was 9AM +7t minutes

To Find:

find the present time

Step-by-step explanation:

Let the present time x .

So according to the question,

x + t minutes = 12 AM ..............(1)

x- 44 minutes = 9 AM + 7t minutes ...............(2)

Subtracting equation 1 and equation 2

( t + 44 ) minutes = (12-9) hours - 7t minutes

t + 44 = 3 hours -7t minutes

(t + 7t + 44) minutes = 180 minutes

8t +44 = 180

8t = 180 - 44

8t = 136

t = 17 minutes

So the correct timing will be 12 AM - 17 minutes  = 11 : 43 AM
