Question

In a class of $45$ students and $8$ teachers, each student got sweets that are $20$% of the total number of students and each teacher got sweets that are $40$% of total number of students. How many sweets were there ?

• A. $484$
• B. $549$
• C. $449$
• D. $600$

Answer 1

The correct option is B $549$

Number of sweets, each student get $=20$% of $45=9$
Total number of sweets students get $=9\ast 45=405$

Number of sweets, each student get $=40$% of $45=18$
Total number of sweets teachers get $=18\ast 8=144$

Total number of sweets $=405+144=549$
