Suppose, Anil (A) is P years younger to Vivek (V).
Now, A = V – P .......( ⅰ )
A = T + P .......( ⅱ )
On adding eq.( ⅰ ) and ( ⅱ ) , we get
A + A = V – P + T + P
the total of the ages of Vivek and Tarun is 48 years
⇒ 2A = V + T = 48

Correct Option: C

∴ A =	48	= 24 years

Suppose, the present age of son be P years.
Therefore, the present age of father = 4P years
According to the question,
4 years ago , 8 ( the present age of son – 4 years ) = ( the present age of father – 4 )
4 years ago , 8 (P – 4) = 4P – 4
⇒ 8P – 32 = 4P – 4
⇒ 8P – 4P = 32 – 4
⇒ 4P = 28

Correct Option: B

∴ P =	28	= 7
	4

Hence ,the present age of son be 7 years.

Suppose age of son = P years
Age of the man = 4P years
Age of man’s wife = 4P – 3 years
According to the question,
After 3 years, age of son + 3 years = 15
P + 3 = 15
∴ P = 15 – 3 = 12 years

Correct Option: D

Suppose age of son = P years
Age of the man = 4P years
Age of man’s wife = 4P – 3 years
According to the question,
After 3 years, age of son + 3 years = 15
P + 3 = 15
∴ P = 15 – 3 = 12 years
Now, age of wife = 4P – 3 years
age of wife = 4 × 12 – 3 years
age of wife = 48 – 3 years
age of wife = 45 years

Suppose the present age of son = P years
Therefore, the present age of Dr. Pandey = 4P years
According to question ,
After 10 years, ( The present age of Dr. Pandey + 10 yaers ) = 2 ( the present age of son + 10 years )
4P + 10 = 2 (P + 10)
⇒ 4P + 10 = 2P + 20
⇒ 4P – 2P = 20 – 10
⇒ 2P = 10

Correct Option: B

∴ P =	10	= 5 years
	2

Therefore , The present age of Dr. Pandey’s son is 5 years .
