10. Predict the output:
a. x = 75
if x > 100:
y = x * 0.20
elif x > 50:
y = x * 0.10
else:
y = x * 0.05
print(y)
b. count = 0
for i in range(1, 6):
if i % 2 == 0:
count += 1
else:
count += 2
print(count)
c. a = 3
b = 4
for i in range(1, 4):
if a > b:
a -= 1
elif a < b:
b -= 1
else:
a += 1
print(a, b)
