PROBLEM:
Given the population P and number of literate people L in Chefland, check if the literacy rate is at least 75\%.
EXPLANATION:
As the statement mentions, the literacy rate is \frac{L}{P} \cdot 100 \%.
More specifically, the literacy rate is \geq 75\% if and only if \frac{L}{P} \geq 0.75, i.e, the proportion of people that are literate is at least 0.75.
So, simply use an if
condition to check whether \frac{L}{P} \geq 0.75 or not.
TIME COMPLEXITY:
\mathcal{O}(1) per testcase.
CODE:
Editorialist's code (Python)
for _ in range(int(input())):
p, l = map(int, input().split())
print('Yes' if l/p >= 0.75 else 'No')
