Answer 1

Lateral Inversions in Plane Mirrors

The word ‘AMBULANCE’ is opposite because when the driver of the vehicle ahead of the ambulance looks in her/his mirror, the person can read it as ‘AMBULANCE’ and give way to it.

Answer 2

25 men will take 3 days to plough 30 acres.

Given : 5 men take 9 days to plough 18 acres land.

To find : The time taken by 25 men to plough 30 acres.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the the required number of days)

Here, we will be using the general arithmetic method.

So,

5 men plough 18 acres land in = 9 days

1 man ploughs 18 acres land in = (9×5) days

1 man ploughs 1 acre land in = (9×5)/18 days

1 man ploughs 30 acres land in = (9×5×30)/18 days

25 men plough 30 acres land in = (9×5×30)/(18×25) = 3 days

(This will be considered as the final result.)

Hence, 25 men will take 3 days to plough 30 acres.
