Step-by-step explanation:

Given:

Amit, Bharat, Chandan, Dinesh, and Eshwar somewhere between Bharat and Dinesh and Ferguson are cousins. None of them are of the same age, but all of them have birthdays on the same date.

To find:

18) Which of the following is not possible?

19) the ages of Dinesh and Chandan respectively?

Solution:

18)

The youngest is 17 years old and $E$ the oldest is 22 years old. $F$ somewhere between and $B\ and D$ in age. $A$is older than $B . C$ is older than $D$.

Here there are four possibility -

First -

$E(22) > A(21) > C(20) > B(19) > F(18) > D(17)$

Second -

$E(22) > C(21) > A(20) > B(19) > F(18) > D(17)$

Third -

$E(22) > A(21) > C(20) > D(19) > F(18) > B(17)$

Fourth -

$E(22) > C(21) > A(20) > D(19) > F(18) > B(17)$

From the all cases, $F$ is 18 years old.

Hence, "option B" is the correct answer.

19)

Suppose that Dinesh is elder to Bharat

• This would mean that Bharat is 17 years old.
• Since Chandan is elder to Dinesh and Ferguson is somewhere between Bharat and Dinesh in age, Dinesh’s age can be either 19 years or 20 years.
• If Bharat is 17 years old, Dinesh can be either 19 years old or 20 years old. Further, if Dinesh is 19 years old, Chandan can be either 20 years old or 21 years old. Therefore, the ages of Dinesh and Chandan can be 19 years and 21 years respectively. So, B is the correct option.
