If he sold 360 kilograms of pears that day, how many kilograms did he sell in the morning and how many in the afternoon? This must be equal to 360.$3x = 360$$x = \frac$$x = 120$ Therefore, the salesman sold 120 kg in the morning and $2\cdot 120 = 240$ kg in the afternoon. Together the three of them picked 26 kg of chestnuts. So $x 2x x 2=26$$4x=24$$x=6$ Therefore, Peter, Mary, and Lucy picked 6, 12, and 8 kg, respectively.

Solution: Let $x$ be the number of kilograms he sold in the morning. Problem 2 Mary, Peter, and Lucy were picking chestnuts. Solution: Let $x$ be the total number of pages in the book, then she finished $\frac\cdot x$ pages.

Here AB represents height of the tower, BC represents the distance between foot of the tower and the foot of the tree.

Now we need to find the distance between foot of the tower and the foot of the tree (BC)θ = Opposite side/Adjacent sidetan 30° = AB/BC1/√3 = 30/BCBC = 30√3 Here BC represents height of the light house, AB represents the distance between the light house from the point of observation.

In the right triangle ABC, the side which is opposite to angle 60 degree is known as opposite side (AB), the side which is opposite to 90 degree is called hypotenuse side (AC) and remaining side is called adjacent side (BC).

Now, we need to find the distance between foot of the ladder and the wall.

Solution: Let x be the amount of milk the first cow produced during the first year.

Then the second cow produced $(8100 - x)$ litres of milk that year.

Solution: If each of $tractors ploughed 0$ hectares a day and they finished the work in $days, then the whole field is: 0\cdot 6 \cdot 4 = 720 \cdot 4 = 2880$ hectares.

Let's suppose that each of the four tractors ploughed $x$ hectares a day.
