In a group of five friends, each has a different age. Sony is younger than Ramesh. Mohan is younger than Chand. Only two people are older than Chand. Sita is younger than Mohan. Who is the second youngest in the group?
Mohan
Sita
Sony
Chand
Mohan
Represent age in a sequence from oldest to youngest and use the anchor point 'Only two are older than Chand' to fix the middle position.
Represent age in a sequence from oldest to youngest and use the anchor point 'Only two are older than Chand' to fix the middle position.
Define the sequence based on the constraints
Let the order be 1 (oldest) to 5 (youngest). 'Only two people are older than Chand' means Chand must be at position 3. So, _ > _ > Chand(3) > _ > _.
Incorporate remaining relationships
We know Mohan is younger than Chand (so Mohan is 4 or 5) and Sita is younger than Mohan (so Sita must be 5). Since Sita is 5 and Mohan is 4, they occupy the last two spots. Remaining are Sony and Ramesh at positions 1 and 2.
Final verification
With Sony younger than Ramesh, the sequence is Ramesh(1) > Sony(2) > Chand(3) > Mohan(4) > Sita(5). The second youngest is Mohan.
B: Sita is the youngest at position 5. C: Sony is the second oldest at position 2. D: Chand is in the middle at position 3.
A is correct because, based on the established sequence (Ramesh > Sony > Chand > Mohan > Sita), Mohan occupies the 4th position, making him the second youngest in the group.
In ranking puzzles, always place the person with a fixed position (like 'two people older than X') first, then map the relative constraints around them.
