Dear Administrator,

There are two answers accepted as best solutions for yesterday's question.

Please confirm which one is correct ...................................
one from West Bengal group
.....................................
3 boys and 4 girls in a row can be arranged in a row in 7! or 5040 ways. Now let G1 and G2 be 1 single entity. Then 7-1 or 6 people can be arranged in 6!*2= 1440 ways. Similarly, if we take B1 and B2 as 1 single entity then they can also be arranged in ^!*2= 1440 ways. Again, if we take the two girls G1 and G2 as a single entity and the two boys B1 and B2 as another single entity then the 5 persons can be arranged in 5!= 120 ways. Therefore, no. of methods to place 3 boys and 4 girls in a row in such a way that neither two girls G1, G2 nor two boys B1, B2 are taken together are= 5040-1440-1440+120= 2280...... Option 9)
........................................

OR
...............................................................
one given by you ................................................
There are three other members besides B1, B2, G1 and G2.
Methods to place these three members = 3.2.1
After then methods to place two boys between them = 4.3
Then methods to place two girls between them = 6.5
Total methods = 3.2.1.4.3.6.5 = 2160

I agree with CT.
same is the case with me.

But CT was approaching the deadline for securing above 95 marks ( Sorry CT , This is ur badluck) for which m4maths was supposed to give a prize. But I was not a contender for the prize.

So I should get the marks as others have got with same logic and same answer.

Again statement of question dated 8.7.10 is confusing.

100000 rupees are deposited in BOB at a rate of 7 % interest per annum added half yearly. Total output will be?

It is not clear after how much time the final output is required .
Also whether 100000 rupees are added half yearly or interest is added half yearly.

I have solved the question assuming that amount is deposited once and interest is added half yearly and total amount is calculated after one year.

In today's question regarding density, there is some doubt.

If same water or water from same source is filled in two buckets of different volumes and density of water is asked, question seems simple. If you want to ask about overall density of bucket filled with water and air, then weight of bucket in both cases and density of air is also required.

Again the language problem in the question today .

Strength of a solution of salt is 60 gm/litre. After adding 5 litre of water, the new strength in gm/litre will be......

Here it is not mentioned that what is the initial volume of solution in which 5 litres of water is added.

I have solved the question assuming that 5 litres of normal water is added to 1 litre of solution having Strength of salt as 60 gm/litre.

If 5 litres of normal water is added to 5 litre of solution having Strength of salt as 60 gm/litre, then answer will be different.

Please clarify if possible.

Dear Sir,

If the question would have been about 9 lines of equal length, then definitely the answer of 5 triangles would have been correct. But for 9 sticks of equal size, 7 triangles were possible.

Thanks a lot for considering that.

Dear Sir,
Thanks a lot for reconsidering the puzzle of 10.3.2010. I have never stated that question is of 5th standard. I have taken the question in right spirit considering the members of this site . I have only stated that if the question is asked in junior class, that answer of 5 would also be acceptable. But I wish that this site should emerge stronger and give due consideration to all possibilities within given conditions of question.

Please excuse me if any of my statement has hurt feelings of anyone . Once again thanks a lot for giving due regards to observation of members.

Dear Friends,

it is your mistake that u r expecting great vision and proper answer from administrator.

I have already solved this puzzle on orkut and I new that answer is 7. But considering the earlier experience and level of this site, I took the risk and got marks for giving wrong answer as 5.

Keep it up , admin.

well explained, Dpin. The administrator has solved this puzzle with limited vision and simple approach in single plane only. In single plane maximum 5 triangles can be made by any 5th standard student as pointed out by Shikha. In the arrangement suggested by Dipin, 7 triangles can be made as desired in question for max no of triangles by arranging 9 equal sticks.

There is no constraint for arrangement of sticks in one plane only. I appreciate the approach of Shikha and Dipin. I hope that administrator will definitely consider the request of Shikha and think again with open mind to accept this solution gracefully.

Dear Siddhartha,

If u can visualise , then I shall try to explain here.

Make an equilateral triangle with 3 sticks in centre.... Now with 3 sticks on each side , make two triangular pyramids on each side of this base.

Each pyramid will have 3 triangles.

so total 3+3+1 ( common ) =7 triangles
