1.	When a lactometer is used in a given sample of milk A, if floats in the milk such that half of the length of its stem is immerse in the milk. When it is used in another sample of milk B, the length of the stem immersed in the milk is one fourth of the total length. Then which of the following is /are true? (A) Water content in A is more than that of B. (B) Density of the sample A is less than the density of the sample B. (A) a is true, but b is false (B) a and b are false (C) a and b are true (D) a is false, but b is true
Answer» (C) a and b are true The lactometer stem is more sinking in milk A compared to sample milk B. So, → Water content in A is less than B → Density of sample A is less than density of the sample B.
