Question

Сумма двух чисел равно 140 . найдите эти числа , если 8 % первого числа равны 6 % второго ?

Answer 1

Х - первое число
(140-х) - второе число
0,08х=0,06(140-х)
0,08х+0,06х=8,4
0,14х=8,4
х=60 - первое число
140-60=80 - второе число

Answer 2

Finding the Two Numbers

To find the two numbers whose sum is 140 and where 8% of the first number is equal to 6% of the second number, we can use a system of equations to solve for the two unknowns.

Let's denote the first number as x and the second number as y.

We have the following information: 1. x + y = 140 (the sum of the two numbers is 140) 2. 0.08x = 0.06y (8% of the first number is equal to 6% of the second number)

Solving the Equations

We can solve this system of equations to find the values of x and y.

First, we can use the second equation to express y in terms of x: y = (0.08/0.06)x

Then, we can substitute this expression for y into the first equation: x + (0.08/0.06)x = 140

Solving for x: x + (4/3)x = 140 (7/3)x = 140 x = (3/7) * 140 x = 60

Now that we have the value of x, we can find the value of y: y = 140 - x y = 140 - 60 y = 80

Conclusion

Therefore, the two numbers are 60 and 80.
