Topic:
It's simple.
Xiao Ming took his two younger sisters to the Lantern Festival. When someone asked them how old they were, they said mischievously: "The product of our age is 6 times the sum of our ages."
Xiao Ming added: "They are not twins, and the difference in age must be no more than 8 years old."
Please write: the age of Xiao Ming's younger sister.
Solution:
Fill-in-the-blank questions are mainly fast.
Set the younger sister’s age to i and keep increasing the value of i.
While increasing the value of i, set the older sister’s age to j.
When j is less than i + 8 and satisfies the product of i and j, i and j When the sum of j is 6 times, the
smaller i is output
Code:
for i in range(1, 50):
j = i + 1
while j <= i + 8:
if j * i == (j + i) * 6:
print(i)
break
else:
j += 1
