Correct Answer: 900
Solution :
Given: The number is divisible by both 10 and 15.
Finding the lowest multiple of two or more numbers is done using the LCM method.
LCM of 10 and 15 = 30
The prime factors of 30 = 2 × 3 × 5
Make it a perfect square number,
30 × 2 × 3 × 5 = 900
Hence, the correct answer is 900.
