Answer:

  • See below

Step-by-step explanation:

Given:

  • Total number = 700
  • Off grid class = 450
  • Online class = 320
  • Both = 275

Based on the given we find the following

1) Off-grid class only:

  • 450 - 275 = 175

3) Online class only:

  • 320 - 275 = 45

2) None of the classes:

  • 700 - (175 + 275 + 45) = 205

4) Not online:

  • 700 - 320 = 380

5) Not off-grid:

  • 700 - 450 = 250
