Answer:

Age of a younger person (wife) is 36 years.

Step-by-step explanation:

The sum of a man and his wife is 81 years.

Also, ratio of their ages is 5:4

Let ages of a man and his wife be 5x and 4x.

Therefore,

5x+4x=81\\9x=81\\x=9

Age of man =5x=5(9)=45 years

Age of his wife =4x=4(9)=36 years.

So,

age of a younger person (wife) is 36 years.

There is two event that needs to be made: 1. blue eyes, and 2. brown eyes. A spinner is made with a circle. A full circle has 360 degrees and it would be divided based on the probability of the event.
Blue eyes have 25% chance, so the angle of the spinner would be 25%*360°= 90°
Brown eyes have 75% chance, so the angle of the spinner would be 25%*360°= 270°

So, the 90° of the circle would be written as 1(blue eyes) and 270° of the circle will be written as 2(brown eyes).
