Answer:
Ram: 21, Hari: 12
Step-by-step explanation:
To solve the problem, we can use the following notation. We call:
= Ram's age at present
= Hari's age at present
We know that:
- Ram is 9 years older than Hari --> mathematically, this can be written as
![r=h+9](https://tex.z-dn.net/?f=r%3Dh%2B9)
- Three years ago, Ram was two times as old as Hari was --> mathematically, this can be written as
![r-3=2(h-3)](https://tex.z-dn.net/?f=r-3%3D2%28h-3%29)
where (r-3) is Ram's age 3 years ago, while (h-3) is Hari's age 3 years ago
Substituting eq.(1) into eq.(2), we find:
![(h+9)-3=2(h-3)\\h+9-3=2h-6\\h+6=2h-6\\h=12](https://tex.z-dn.net/?f=%28h%2B9%29-3%3D2%28h-3%29%5C%5Ch%2B9-3%3D2h-6%5C%5Ch%2B6%3D2h-6%5C%5Ch%3D12)
So, Hari's age is 12; therefore, Ram's age is
17 sikkke just google that dude
The figure is really just 3 triangles and 1 rectangle, as you see in the picture below.
notice the blue triangle has a base of 3 and a height of 2,
the green triangle has a base of 6 and a height of 1,
the yellow triangle has a base of 2 and a height of 6,
and the rectangle is a 7x6 rectangle.
we can simply get the area of each and sum them up, that's the area of the figure.
The answer is 50%.
25 is the half of 50. Therefore, 25 is 50% of 50.
