Let the larger number be x
and, smaller number be y
Then, according to question:
x = 4y + 56 ….(1)
6x - 6y = 678
x -y = 113 .…(2)
Now, putting value of x from equation 1 to equation 2, we get
4y + 56 - y = 113
3y = 113 - 56
3y = 57
y = 57/3
y = 19
Now, putting value of y in equation 1, we get
x = 4(19) + 56
x = 76 + 56
x = 132
Thus, the larger number is 132 .
