Question

plssss answer..............

Answer 1

9) 70 trees were planted by parth
90 trees were planted by pradnya
out of this 25 trees were planted by both of them
Trees planted by parth and pradnya = 70 + 90 - 25 = 135

10) total no of students = 125
out of this 80 students drink tea
60 students drink coffee
20 students drink both
125 = 80 + 60 + x - 20
x represents students who don't drink both
125 = 120 + x
x = 125 - 120
x = 5
so 5 students don't drink both tea or coffee
