A watermelon weighs 2kg and contains 92% of water. After putting in the sun, the water of the watermelon only contains 90% of water. At that time, how many kilograms does that watermelon weigh ?
Lượng nước trong quả dưa hấu: 2 x 92% = 1,84 (kg)
90% lượng nước còn lại: 1,84 x 90% = 1,656 (kg)
Khối lượng quả dưa bị giảm: 1,84 – 1,656 = 0,184 (kg)
Sau khi phơi nắng quả dưa hấu cân nặng: 2 – 0,184 = 1,816 (kg)
