The number of odd positive divisors of 67500 is
- A \(16\)
- B \(18\)
- C \(20\)
- D \(22\)
Answer & Solution
Correct Answer
(C) \(20\)
Step-by-step Solution
Detailed explanation
\(\because 67500=2^2 \times 5^4 \times 3^3\) No. of divisors \(=(2+1)(4+1)(3+1)=60\) No. of odd positive divisors \(=\frac{60}{(2+1)}=20\)
