Directions : For the Assertion (A) and Reason (R) below, choose the correct alternative

Assertion(A) : Graphite is slippery and used as a lubricant.

Reason (R) : Graphite has free electrons.

A) Both A and R are true and R is the correct explanation of A.	B) Both A and R are true but R is NOT the correct explanation of A.
C) A is true but R is false.	D) A is false but R is true.

Answer & Explanation Answer: B) Both A and R are true but R is NOT the correct explanation of A.

Explanation:

Graphite possesses a layer structure with two successive layers held by weak forces and able to slide over one another. So, graphite is slippery and this property finds its use as a lubricant. In graphite, each carbon atom is linked to three other carbon atoms while one electron in the carbon atom is delocalised. So, graphite has free electrons

Q:

Ravi's brother is 3 years senior to him. His father was 28 years of age when his sister was born while his mother was 26 years of age when he was born. If his sister was 4 years of age when his brother was born, what were the ages of Ravi's father and mother respectively when his brother was born ?

A) 32 years, 23 years	B) 32 years, 29 years
C) 35 years, 29 years	D) 35 years, 33 years

Answer & Explanation Answer: A) 32 years, 23 years

Explanation:

When Ravi's brother was born, let Ravi's father's age = x years and mother's age = y years.

Then, sister's age = (x - 28) years. So, x - 28 = 4 or x = 32.

Ravi's age = (y - 26) years. Age of Ravi's brother = (y - 26 + 3) years = (y - 23) years.
