Final answer:

To find the consecutive even numbers with a sum of 22, subtract 2 from the first number and set it equal to the second number. To find the sum where 10% of it is equal to Rs 40, divide Rs 40 by 0.1.


Step-by-step explanation:

To find the consecutive even numbers with a sum of 22, we can set up the equation:

x + (x+2) = 22

Simplifying the equation gives us: 2x + 2 = 22

Subtracting 2 from both sides of the equation gives us: 2x = 20

Dividing both sides of the equation by 2 gives us: x = 10

So the two consecutive even numbers are 10 and 12.

To find the sum where 10% of it is equal to Rs 40, we can set up the equation:

0.1x = 40

Dividing both sides of the equation by 0.1 gives us: x = 400

So the sum is Rs 400.
