Use the following passage for the questions based on it. Rahul and Kusum are good in Hindi and Maths, Sameer and Rahul are good in Hindi and Biology. Gita and Kusum are good in Marathi and Maths. Sameer, Gita and Mihir are good in History and Biology. Who is good in both Biology and Marathi? A. Gita B. Kusum C. Sameer D. Mihir Correct Answer A
The combinations are:
Rahul + Kusum = Hindi + Maths------ (i )
Sameer + Rahul = Hindi + Biology-------(ii)
Gita + Kusum = Marathi + Maths-------(iii)
Sameer + Gita + Mihir = History + Biology-------(iv)
There can be two possible combinations for Marathi and Biology:
Using (ii) and (iii)
Sameer + Rahul = Hindi + Biology-------(ii)
Gita + Kusum = Marathi + Maths-------(iii)
But here no one is common so we cannot determine that person who is good in both Marathi and Biology.
Using (iii) and (iv)
Gita + Kusum = Marathi + Maths-------(iii)
Sameer + Gita + Mihir = History + Biology-------(iv)
Here Gita is common, so Gita is good in both Biology and Marathi.
