Producers are organisms that have the ability to manufacture their own food. Plants are producers since they make their own food using the process of photo synthesis. At the equator the mass of producers or plants is highest and this value decreases as one moves north or south of the equator. This is because the optimum conditions for plant growth exist there. therefore this means the mass of produces consumed would decrease moving from the equator to the poles.
Answer:
Present age of woman = 38 years.
Present age of Daughter = 8 years.
Explanation:
Given :
The sum of the ages of a woman and her daughter = 46 years.
In 4 years time,the ratio of their ages = 7:2.
Solution :
Let assume,
Present age of woman = x years
Present age of Daughter = y years
as given,
The sum of the ages of a woman and her daughter = 46 years.
x+y = 46
x = 46 - y.................(equation 1)
and,
In 4 years time, the ratio of their ages = 7:2.
After 4 years,
Age of woman = (x+4) years
Age of daughter = (y+4) years
→ (x+4) : (y +4) = 7:2
→ x+4/y+4 = 7/2
→ 46-y+4/y+4 = 7/2
→ 50-y/y+4 = 7/2
→7y +28 = 100-2y
→ 7y +2y = 100 -28
→ 9y = 72
→ y = 8
so, y = Present age of Daughter = 8 years.
Put the value of y = 8 in equation (1) .
→ x = 46 - y
→ x = 46 - 8
→ x = 38
Thus, the Present age of woman = x = 38 years.
