Sir please explain siblings question how it is 8. As there are 7 sisters and 7 brothers it means total 14 siblings

1. Are there 7 brothers? It is said “each sister has a brother” – if there is one brother, say X, then each sisters here have X as their brother! So, he’s the on;y brother of all 7 sisters!

2. sumit kundu says:

7 sisters have common brother that’s why they are 8, how could sisters have eich different brother

3. eric 13 says:

As it says one brother for each sister which means that there is one brother and he is the only brother to each sister….

Answer for odd one out is rectangle all others have equal sides

1. Does isosceles triangles have all sides equal? Or does equilateral triangles have all sides equal?

2. Deepanshu Aggarwal says:

Sorry but all sides are not equal in isoceles triangle.

7. Deepanshu Aggarwal says:

In case of rectangle,square and hexagon, All the angles between sides are equal but in case of isoceles triangle only two angles are equal.Therefore isoceles triangle is odd one.

1. Deepanshu Aggarwal says:

Thanks sir/madam but i need keys also for physical sciences.

8. Sajin Ponnan says:

probability of getting six is not 1/6.

1. It is a fair die. So the outcome of the first 3 throws will not affect the outcome of the 4th throw. Hence the answer should be 1/6.
If it was a biased die, your answer would have been correct.

1. Sajin Ponnan says:

your explanation is inappropriate to convince me.

In this question the die throw 4 times.
total number of events = 6^4 = 1296.
in previous 3 throws outcome was 6. question is to find probability of getting 6 in 4th throw, that is the probability of getting particular event (6,6,6,6).
number of that particular event is 1.

Then the probability = 1/1296

1. The question is NOT to find the probability of getting particular event (6,6,6,6).The first 3 events already happened and we dont have to find the probability of that 3 events to happen. We are only required to find the probability of getting the 6 in the last throw.

How 474 be an answer based on divisibility test?

1. All the numbers in the list except 474 is a multiple of 11. Thus 474 is the odd one out and hence the answer.

1. Sumanta Ghosh says:

But 154 is divisible by 7 ..others are not

1. Sumanta Ghosh says:

And also 363 is not divisible by 2 but others

Only 474 can’t be divided by 22
Rest all can be

14. mahesh says:

plz update answer key of part B and part c.it urgent

15. ASHISH says:

Dear sir Why 572 can’t be reply to divisibility test question. As all three are not divisible by 4 and only 572 is divisible.

1. Ashish, 474 is the only number which is not divisible by 11. All others are divisible by 11.
In the logic you used, the problem is that 572 is the only number holding that property .
By that logic 154 can also be the answer as it is the only number divisible by 7.
But 474 being the answer have a more reasonable logic as it is the only number which is not a multiple of 11. If you can rule out the divisibility of any number for all but one options, then that also can be the answer. But 154 or 572 doesn’t satisfies such a condition.

1. Mubashir qayoom says:

also sir only sum of digits of 474 can’t be divided by 2 while as sum of digits of other numbers can

1. The question asks to use divisibility test. But here in your explanation, divisibility test is not used.

Please post answers for Part B and Part C of physical science. It will be very helpful. Thank you.

572 is only divisible by 4 others are not

Sir train vale question ka answer 45 hoga

19. Vijaya P Godase says:

Christy Sir,

1. Try with values of N. Start with N=2. You can eliminate 2 options.
Then try N=3, you will get the answer.

Both A and B does not tell a lie in the same day of the week

1. The question doesn’t ask the day in which both of them lie. Instead it asks about the day in which both A and B say that they lied yesterday.
