Step-by-step solution
Rima studies six subjects viz. Hindi, English, Maths, History, Science and Computer on six different days of a week that starts from Monday. Only one subject is studied each day and one of the days is Holiday.
Which day is Holiday?
Statement I:& Hindi is studied just after Science, which is studied on the fourth day of the week. Saturday is not a Holiday. Computer is studied just before Holiday.
Statement II:& Hindi and Computer are studied at a gap of three days. Maths is studied on the last day of the week. English and Hindi are studied on consecutive days.
Checking statement I:
As per the given hints, following arrangement can be prepared.
Which day is Holiday?
Statement I:& Hindi is studied just after Science, which is studied on the fourth day of the week. Saturday is not a Holiday. Computer is studied just before Holiday.
Statement II:& Hindi and Computer are studied at a gap of three days. Maths is studied on the last day of the week. English and Hindi are studied on consecutive days.
Checking statement I:
As per the given hints, following arrangement can be prepared.
| Days | Subjects |
| Monday | |
| Tuesday | |
| Wednesday | |
| Thursday | Science |
| Friday | Hindi |
| Saturday | |
| Sunday |
Thus,the Holiday cannot be determined.
Hence data in statement I is not sufficient to answer the question.
Checking statement II:
As per the given hints no information about Holiday is given.
Hence data in statement II is not sufficient to answer the question.
Checking both statements I and II:
| Days | Subjects |
| Monday | Computer |
| Tuesday | Holiday |
| Wednesday | |
| Thursday | Science |
| Friday | Hindi |
| Saturday | |
| Sunday | Maths |
Thus Tuesday is Holiday.
Hence data in both the statements is necessary to answer the question.
Hence option D is correct.
