Answer 1

Answer:

Thursday is correct answer

Answer 2

The net capacity of ground water by 2014 is  90002

Given:

The capacity of a ground was 100000 at the end of 2012. In 2013, it increased by 10% and in 2014, it decreased by 18.18%

To Find:

The ground’s capacity at the end of 2014

Solution:

When One percentage change is positive and the other is negative:

x is positive and y is negative,

Then net percentage change,

= (x-y-xy/100)%

Final Percentage Change over the original value,

= 10-18.18 – (10 × 18.18/100)

= -9.998

(the difference above is cause by using exact values).

So the capacity of the ground is decreased by 9.998%

Hence, net capacity = 90002
