Answer 1

Answer:

4 messages

Step-by-step explanation:

birthday greetings = 90/100 * 40

= 36 messages

other = 40 - 36

= 4 messages

Answer 2

Given,

No. of messages= 40

% of birthday greetings=90%

Therefore,

% of other messages =(100 - 90) %

                                   =10%

Therefore,

No. of other messages= 10% of 40

                                     =10/100 × 40

                                     =4
