Answer 2

Answer:

Step-by-step explanation:

I m not going into details.

If you are told to increase a number in a particular ratio, just reverse the ratio and multiply it with the number. If you are told to decrease a number in a particular ratio, just multiply it with the number.

So here, (1200×7)/3 which gives 2800.

Now we need to increase this new number.

Here, (2800×7)/4 which is 4900.
