no. of followers are 45000.What will be the total no. of followers after three weeks?

Answer 1

Answer:

Well it's simple if you read the question properly.

Increase of followers by week = 25%

Increase of followers by three weeks=

25% *3= 75%

Increase in the number of followers=.

No. of present followers + ( no. of followers * 75/100)

=> 45000 +(45000*75/100)

I have done the calculation in the picture.

Answer 2

Given:

Increase rate per week = 25%

Now,

Increase of followers by 3 weeks will be,

= 25% × 3

= 75%

Number of follower = 45000

To Find:

Total number of followers after 3 weeks = ?

Solution:

Now,

Increase in number of followers = Number of % followers + Number of followers × 75/100

On putting the values in the above formula, we get

= $45000+(45000\times \frac{75}{100} )$

= $45000+(450\times 75)$

= $45000+33750$

= $78750$

Thus, after 3 weeks, the total number of followers will be "78750".
