Answer 1

There was a total of 18 apples

Explanation:

Let us consider the total no. of apples be 'a'.

Patriarca took 1/6 of the apples. So the remaining apples is,

a - (1/6) a= (5/6) a

Step 1:

His wife takes (1/5) of the rest of the apples. So after she takes the apples the remaining apples will be,

(5/6) a - (1/5) (5/6) a

(5/6) a - (1/6) a = (4/6) a

Step 2 :

Her elder son takes (1/4) of the remaining apples. So,

(4/6) a - (1/4) (4/6) a

(4/6) a - (1/6) a = (3/6) a

Step 3:

Middle son takes (1/3) of the remaining apples. So,

(3/6) a - (1/3) (3/6) a

(3/6) a - (1/6) a = (2/6) a

Step 4:

Younger son takes (1/2) of the remaining apples. So,

(2/6) a - (1/2) (2/6) a

(2/6) a - (1/6) a = (1/6) a

After work she takes the remaining 3 apples. So the remaining apples were 3

So,

(1/6) a = 3

a = 3 x 6

a = 18 apples

There were a total of 18 apples.
