The larger number is 66 and the smaller number is 14.
Step-by-step explanation:
Let,
The larger number = x
The smaller number = y
According to given statement;
x-y=52 Eqn 1
5y = x+4 Eqn 2
From Eqn 2
x = 5y-4 Eqn 3
Putting value of x from Eqn 3 in Eqn 1
Dividing both sides by 4
Putting y=14 in Eqn 3
The larger number is 66 and the smaller number is 14.
