Ques:- Sum of two numbers is 80. Greater number exceeds by 5 from four times of the smaller. Find the numbers?

Recent Answer : Added by Admin On 2022-09-29 18:30:23:

Let x and y be the two numbers. And x > y.
Then,
x + y = 80—–(1)
y=80-y
Also,
x = 4y – 5
Solving the two equations,
80 – y = 4y – 5
85 = 5y
Therefore, y = 17
put the value of y in equation(1)
then
x+y=80
x+17=80
x=63
the numbers are 17&63
