Answer,
Present age of MOTHER = 50
And
DAUGHTER = 20

EXPLANATION-
Lets Mother’s Age be M
and Daughter’s agr be D

So,
Given
(M-10) = 4(D-10)      –   I
and
(M+10) = 2(D+10)     –     II

Solving both equation,

M = 4D-30 (From I)        –    III

In Equ II-
4D-20=2D+20
2D=40
D=20

and substituting in III
M=50

Its just similar to 25 Horse and 5 track puzzle (First solve it)

Lets say N=10
Here we have,
12 Teams(Horses) and 2 (Teams can play a match)Track and find Top 2

MATCH #1 – 5 Matches
A1 – B1
A2 – B2
A3 – B3
A4 – B4
A5  – B5
A6  – B6

Lets say, all A’s are winner
So,
MATCH #2 – Next tournament(3 Matches)-
A1-A2
A3-A4
A5-A6
Now we have winner- A1,A3 and A5

MATCH #3 – Next Tournament – (3 Matches)
A1-A3
A3-A5
A1-A5
Now we’ll get 2 winners lets say – A1,A3(A1 is winner and A3 runnerup)

In MATCH #4 – (1 Matches)
We’ll take winners opponent in MATCH #2 – A1’s opponent is A4
A4 – A3
Lets say A4 win

In MATCH #5-(1 Matches)
We’ll take winners opponent in MATCH #1- A1’s Opponent B1
B1 – A4
Lets B1 wins So, B1 is 1st Runnerup.

A total of 14 Matches required to find out Winner and runner up in 12 Teams.
