The total number of students in a school is 2100. If the number of boys are 210 more than
the number of girls. Find the number of boys and girls.

Answer 1

Answer Girls=440

Total Nos of Students = X

Then, Girls G = X/3 + 160

Then, Boys B = X/7 + 280

Also G+B + X

Solving this we get 11G = 4840

therefore, Girls G = 440.
