Answer 2

Given :-

• Total number of messages = 40
• Percentage of messages that were brithday greetings = 90%

To Find :-

• Number of other messages he received = ?

Solution :-

Percentage of other messages he received = 100%  - Percentage of messages that were brithday greetings

⇒ Percentage of other messages he received = 100% - 90%

⇒ Percentage of other messages he received = 10%

Number of other messages he received = $\dfrac{\textbf{Percentage of other messages he received}}{\textbf{100}} \; \times \; \textbf{Total number of messages}$

⇒ Number of other messages he received = $\sf \dfrac{10}{100} \times 40$

⇒ Number of other messages he received = 4

∴ Soham received 4 other messages on his birthday.
