Hari (H), Gita (G), Irfan (I) and Saira (S) are siblings, i.e. brothers and sisters. All were born on 1st January. The age difference between any two successive siblings, that is, born one after another, is less than 3 years. Given the following facts: (i) Hari's age + Gita's age > Irfan's age + Saira's age. (ii) The age difference between Gita and Saira is 1 year. However, Gita is not the oldest and Saira is not the youngest. (iii) There are no twins. In what order were they born, oldest first?
- HSIG
- SGHI
- IGSH
- IHSG
Correct answer: IHSG
Solution
Since Gita is not the oldest and Saira is not the youngest, and their age difference is 1 year, they must be adjacent in the birth order with Gita older than Saira. Checking the possible arrangements against the inequality H + G > I + S leaves only IHSG.
