Let 4 consecutive even numbers be x, x + 2, X + 4 and x + 6 respectively.
3 consecutive odd numbers be y, y + 2 and y + 4
According to question,
[x + x + 2 + x + 4 + x + 6]−[y + y + 2 + y + 4] = 81
= > (4x + 12)−(3y + 6) = 81
4x−3y = 81−12 + 6
4x−3y = 75
x + 4 = 59
On solving equations (i) and (ii), we get
X = 36
y = 23
The sum of largest odd and even number = x + 6 + y + 4 = x + y + 10 = 36 + 23 + 10 = 69
3 consecutive odd numbers be y, y + 2 and y + 4
According to question,
[x + x + 2 + x + 4 + x + 6]−[y + y + 2 + y + 4] = 81
= > (4x + 12)−(3y + 6) = 81
4x−3y = 81−12 + 6
4x−3y = 75
x + 4 = 59
On solving equations (i) and (ii), we get
X = 36
y = 23
The sum of largest odd and even number = x + 6 + y + 4 = x + y + 10 = 36 + 23 + 10 = 69
