Question

Некоторое число уменьшили на 15% а затем результат увеличение на 10%

Answer 1

1) пускай было число х;
2) после уменьшения на 15% получим число 0,85х
3) после увеличения на 10% получим число 0,85х+0,085х=0,935х.
То есть начальное число х уменьшили на 6,5%.

Answer 2

Calculation Steps:

To calculate the result of reducing a number by 15% and then increasing the result by 10%, we can follow these steps:

1. Reduce the number by 15%: - Let's assume the original number is represented by "x". - The result of reducing "x" by 15% is given by the formula: x - (0.15 * x).

2. Increase the result by 10%: - The result of increasing the reduced number by 10% is given by the formula: (x - (0.15 * x)) + (0.10 * (x - (0.15 * x))).

Calculation:

Using the above steps, the calculation can be represented as follows:

1. Reduce the number by 15%: - x - (0.15 * x)

2. Increase the result by 10%: - (x - (0.15 * x)) + (0.10 * (x - (0.15 * x)))

Result:

The final result after reducing a number by 15% and then increasing the result by 10% is given by the expression: (x - (0.15 * x)) + (0.10 * (x - (0.15 * x))).
