**Concept: The question tests on Number properties**

**Solution:**

Is n a multiple of 140. i.e is n = 140, 280, 420 ....**Statement 1:** n is a multiple of 10

n = 10 is a multiple of 10, but 10 is not a multiple of 140 (it is a factor of 140)

Answer options could be B, C or E Therefore Statement 1 Alone is **Insufficient **

**Statement 2:**n is a multiple of 14.

n = 14 is a multiple of 14, but not a multiple of 140.

Answer Options could be C or E Therefore Statement 2 Alone is

**Insufficient.**

**Combining Both Statements:**n is a multiple of 10 and 14 i.e LCM of 10 and 14 = 70

n = 70 is a multiple of 10 and 14, but is not a multiple of 140

Therefore Both Statements together are

**Insufficient.**

**Option E**
