Answer:
Option E) 8000
Step-by-step explanation:
It is given in the question that the number of pencils and pens in a container A are 150 and 725.
Let the number of pens and pencils in container B are x and y.
As per statement " Ratio of the number of pencils to the number of pens is 2:3"
Equation will be
Or ------(1)
Second statement says "If all pens and pencils of container B are placed in container A then ratio of pencils and pens would be 3:5"
Equation will be
5(x + 150) = 3(y + 725) [By cross multiplication]
5x + 750 = 3y + 2175
5x - 3y = 2175 - 750
5x - 3y = 1425 ------(2)
Now we put
y = 3×1425
y = 4275
Now we put y = 4275 in equation 1
x = 2850
Now (x + y) = 2850 + 4275
= 7125
Now Total number of pen and pencils in container A and container B
= 150 + 725 + 7125
= 8000
Therefore, Option E) is the answer
You can approximate the square root of 30 by taking the square root of a number close to it. This is called local linearization. You can take the square root of 36, which is 6, and the square root of 25, which is 5, and state that the square root of 30 is approximately somewhere between 5 and 6
