Which of the following conclusions are true?
Which of the following conclusions are true?
1.Lakshmi is taller than Rekha
2.Rekha is shorter than Mita
3.Rekha is taller than Sana
4.Sana is shorter than Ganga
Correct answer
(C) 2 and 4
Solution
From the given statements, we can establish the following height relationships:
1.Ganga Rekha
2.Ganga Lakshmi
3.Lakshmi Sana
4.Mita Ganga
By combining these relationships, we can deduce:- From (4) and (1): Mita Ganga Rekha. This implies Mita Rekha, so conclusion 2 (Rekha is shorter than Mita) is true.
- From (2) and (3): Ganga Lakshmi Sana. This implies Ganga Sana, so conclusion 4 (Sana is shorter than Ganga) is true.
- Regarding conclusion 1: We know Ganga Lakshmi and Ganga Rekha, but there is no information provided to compare the heights of Lakshmi and Rekha directly.
- Regarding conclusion 3: We know Ganga Rekha and Ganga Lakshmi Sana, but there is no information provided to compare the heights of Rekha and Sana directly.
