Question

За первый месяц было вывезено 4 седьмых хранившегося там запаса муки а за второй 15 % оставшейся муки после чего на складе осталось 76,5 т муки сколько всего муки было на складе первоначально

Answer 1

76,5 т-это 100%-15%=85% осталось, значит вывезли
76,5*100/85=90 т было
90т-это 3/7 остаток
90/3*7=210 т было первоначально

Answer 2

76.5/100х15=11.5-15%
76.5+11.5=88т-3/7
88/3х7=205.3т было всего сначала

Answer 3

Calculation of Initial Flour Stock on the Warehouse

To calculate the initial amount of flour on the warehouse, we need to determine the amount of flour that was left after the first month and the amount that was left after the second month.

Let's assume that the initial stock of flour on the warehouse was x tons.

According to the information provided, after the first month, 4/7 of the initial stock was taken out. This means that after the first month, there were (1 - 4/7) * x = 3/7 * x tons of flour left.

After the second month, 15% of the remaining flour was taken out. This means that after the second month, there were (1 - 15/100) * (3/7 * x) = 85/100 * 3/7 * x = 255/700 * x tons of flour left.

The problem states that after the second month, there were 76.5 tons of flour left on the warehouse. Therefore, we can set up the following equation:

255/700 * x = 76.5

To find the value of x, we can solve this equation:

x = 76.5 * 700 / 255

Calculating this, we find that x is approximately 210 tons.

Therefore, the initial stock of flour on the warehouse was approximately 210 tons.

Answer

The initial stock of flour on the warehouse was approximately 210 tons.
