Meets says to his brother that when I will be your age you will be 40 years old and his brother says when I will be your age you will be 4 years old how old they’re
Answers
Step-by-step explanation:
Let present age of Meets be X years
and Present age of His brother be Y years
Let Suppose after Z years she will be her brother's age
A.T.Q
X + Z = Y ; Eq.1
Y + Z = 40; Eq.2
Z = 40 - Y
Putting Value of Z in Eq.1
X + 40 - Y = Y
X + 40 = 2Y
X - 2Y = -40 Eq.3
And Also
Suppose before W years His brother will be meets age.
Y - W = X; Eq.4
X - W = 4; Eq.5
- W = 4 - X
W = X - 4
Putting Value of W in Eq.4
Y - ( X - 4 ) = X
Y - X + 4 = X
Y + 4 = 2X
2X - Y = 4 Eq.6
Multiplying Eq.6 by 2
4X - 2Y = 8 Eq.7
Subtracting Eq. 3 from Eq. 7
4X - 2Y - ( X - 2Y ) = 8 - (-40)
4X - 2Y - X + 2Y = 8 + 40
3X = 48
X = 16
Putting in Eq.6
32 - Y = 4
Y = 32 - 4 = 28
Therefore Present Age of Meet is 16 yrs
And his Brother is 28 yrs
