D. Because Ram only did 2 hours so then that makes 2 hours of work done but then left for whatever reason. Ajit left 3 hours BEFORE the completion of the work and that gives us info that there were hours put in between both Rams and Ajits work. They all started at the same time so it doesn't mean that Ajit didn't do any of the work. Ajit can work for 12 hours POSSIBLY. It did not say he can exact. So it leaves to Suresh that can work up to 15 hours of the work but we dont know how long he did it. Suresh either could just gone over or less than 15 hours.
The correct answer for the exercirse shown in the figure attached is the first option, which is: Calculate the area of the circle A and circle B and calculate the difference.
To calculate the area of the circle A and the circle B, you must apply the formula for calculate the area of a circle, which is shown below:
A=πr²
A is the area of the circle.
r is the radius of the circle.
To calculate the difference, you only have to substract the result of the area of the circle A and the area od the circle B:
At=Aa-Ab

The original equation is 4x - 6 = 22. We can solve this by first isolating x, and that can be done by initially adding 6 to both sides. After doing this, we are left with 4x = 28. Now, we can simply divide both sides by 4, giving us an x value of x = 7. Therefore, the answer to your problem is x = 7. Hope this helped and have a great Halloween!
