Answer 2

Answer: 1000 is the total  number of students in the school

Step-by-step explanation:

75% of total number of students is 750 ---[Given]    

Let the total number of students be 'S'

To find 100% number of students that is the total number of students···                                          

75% of S = 750

∴$\frac{75}{100}$×S = 750

∴S = $\frac{100}{75}$×$\frac{750}{1}$

∴S = $\frac{75000}{75}$

∴S = 1000
