Answer 1

Answer: she needs 67% in fourth semester to secure 75%

Explanation: python code :

a = 82

b = 67

c = 53

d = 87

x = (a+b+c+d)/4

a2 = 88

b2 = 78

c2 = 76

d2 = 69

y = (a2+b2+c2+d2)/4

a3 = 89

b3 = 85

c3 = 91

d3 = 67

z = (a3+b3+c3+d3)/4

ans = 75

v = ans*4

r = v-x-y-z

print(r)
