Answer 1

10 students drinks all

25 students drinks milk and tea

but 10 students are already above

so , 15 students purely drinks milk and tea


20 students drinks milk and coffee

but 10 students are already above

so , 10 students purely drinks milk and coffee


20 students drinks coffee and tea

but 10 students are already above

so , 5 students purely drinks coffee and tea


12 students only milk

5 students only coffee

8 students only tea


so overall ,

10 + 15 + 10 + 10 + 12 + 5 + 8 = 70 students drinks


therefore , 100 - 70 = 30 students can not drink
