Answer: There are 20 socks in the first case and there are 75 socks in the second case.
Step-by-step explanation:
Since we have given that
Number of equal groups = 5
Let the total number of socks be 's'.
According to question, expression will be
Now, Suppose number of socks in each group = 4
So, it will become,
Suppose number of socks in each group = 15
So, Total number of socks become
Hence, there are 20 socks in the first case and there are 75 socks in the second case.
The three integers are 5,17 and -10
Step-by-step explanation:
Let x, y and z be three integers then

'The sum of the first and second integers exceeds the third by 32'

The third integer is 15 less than the first.

From Eqn 2:

Subtracting Eqn 1 from eqn 2

Dividing both sides by -2

Putting z=-10 in Eqn 3

Putting x=5 and z=-10 in Eqn 1

Hence,
The three integers are 5,17 and -10
