The giant pandas Kai Kai and Jia Jia reside at the river safari. The sum of their ages when they first arrived in Singapore in 2013 was 11 years. In 2022, Kai Kai will be three times as old as Jia Jia was in 2013. Find their ages in 2014.​

Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

Jawab:

Let's call the age of Jia Jia in 2013 as x. Then, the age of Kai Kai in 2013 would be 11 - x.

In 2022, Kai Kai will be 3 times as old as Jia Jia was in 2013, so his age in 2022 would be 3 * x + 9 (9 years have passed).

Since the sum of their ages in 2022 is 3 * x + 9 + x = 4 * x + 9, and they both had an age of 11 in 2013, we can set up the following equation to solve for x:

4x + 9 = 11 + 9 = 20

4x = 11

x = 11/4 = 2.75

So Jia Jia was 2.75 years old in 2013, and Kai Kai was 11 - 2.75 = 8.25 years old in 2013. In 2014, Jia Jia would be 2.75 + 1 = 3.75 years old and Kai Kai would be 8.25 + 1 = 9.25 years old.
