Answer 1

Given thαt,

• In α school out of 340 students, 55% students αre of Science.

☯️ We need to find the number of commerce students.

___________

Let the number of commerce students be a.

According to the question,

Number of total students - 55% of total students = Number of commerce students.

:$\implies{\sf{340 - \dfrac{55}{100} \times 340 = a}}$

:$\implies{\sf{340 - \dfrac{55}{10 \cancel{0}} \times 34 \cancel{0} = a}}$

:$\implies{\sf{340 - \dfrac{11}{2} \times 34=a}}$

:$\implies{\sf{340-11 \times 19=a}}$

:$\implies{\sf{340 - 209 = a}}$

:$\large\implies{\boxed{\sf{\red{a = 131}}}}$

Hence, the number of commerce students is 131.

And we are done! :D
