There are five cousins namely Ashish, Manish, Kailash, Daksh, and Lalit of different ages. All these cousins are arranged in the descending order of their ages. Ashish, brother of Kailash, is the second youngest and is 19 years old. Daksh, brother of Lalit, is between Kailash and Manish. Kailash is 42 years old and Ashish is 20 years younger than Daksh. Who among the following is the youngest?

Lalit

Arranging them in descending order of their ages,

1) Ashish is the second youngest and is 19 years old.

2) Daksh is between Kailash and Manish

So, Kailash > Daksh > Manish

3) Kailash is 42 years old and Ashish is 20 years younger than Daksh.

4) Ashish is 19, so Daksh is 39 and Ashish is second youngest

So, Kailash (42) > Daksh (39) > Manish > Ashish (19) > Lalit

Therefore, Lalit is the youngest among all.
