Let Anil's age = x years
Then, Prashant's age = (48 - x) years
Let the age of Jayesh be P years.
Then, P - (48 - x) = x - P

Correct Option: B

Let Anil's age = x years
Then, Prashant's age = (48 - x) years
Let the age of Jayesh be P years.
Then, P - (48 - x) = x - P
⇒ 2p = 48
∴ p = 24

Let Chandravati's age 10 years ago be x years.
∴ mothere's age 10 years ago = 4x years
From Question 2(x + 20) = (4x + 20)

Correct Option: C

Let Chandravati's age 10 years ago be x years.
∴ mothere's age 10 years ago = 4x years
From Question 2(x + 20) = (4x + 20)
⇒ x = 10
∴ Present age of Chandravati = (x + 10) = 20 years

Let their ages one years ago be 4x and 3x years.
∵ (4x + 2)/(3x + 2) = 5 / 4

Correct Option: C

Let their ages one years ago be 4x and 3x years.
∵ (4x + 2)/(3x + 2) = 5 / 4
⇒ 4(4x + 2) = 5(3x + 2)
⇒ x = 2
∴ Sum of their present ages = (4x + 1) + (3x + 1) = 16 years

Let the current ages of A and B be 2x and 5x respectively
Now from question (2x + 8) / (5x + 8) = 1 / 2

Correct Option: B

Let the current ages of A and B be 2x and 5x respectively
Now from question (2x + 8) / (5x + 8) = 1 / 2
⇒ 2(2x + 8) = (5x + 8)
⇒ x = 8
∴ Difference of their ages = (5x - 2x) = 3x = 24 years

Let the ages of A and B be 2x and 3x years respectively.
From question, (2x + 5) / (3x + 5) = 3 / 4

Correct Option: A

Let the ages of A and B be 2x and 3x years respectively.
From question, (2x + 5) / (3x + 5) = 3 / 4
⇒ 4(2x + 5) = 3(3x + 5)
⇒ x = 5
&ther4; A's present age = 2x = 10 years
