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.

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.

Mayur 14 years AGO

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

Surprised to note that accepted answer for the qn of 10.3.10 ..... There are nine sticks of equal size. Maximum number of triangles formed by using these sticks in one attempt are....5...........

If this question is asked in a class of 5th standard , then this answer would have been acceptable and consolation prize/marks can be given to the student for this answer.

But when this question is asked at a site called www.m4maths.com with participating members from Elite organisations and ccolleges/schools , then answer is not correct.
..................
One can make maximum 7 triangles if thjese 9 sticks are properly used.
...........................
7 triangles can be achieved by making two triangular pyramids with common base.

Then each pyramid will have 3 triangles and one common base triangle making total 7 triangles.
........................
Please check it with open mind.
........................
You may not give marks to me for this qn but this ans of max 5 triangles is not correct.

Dear Sir,

Please read the qn and options

Six men do a piece of work in 10 days with an effort of 6 hours per day. How many extra men are required for doing the work of double strength in 4 days with an effort of 5 hours per day

1) 3
2) 2
3) 1
4) 4
5) 5
6) 6
7) 7
8) 8
9) 9
10) 0


Your calculation for men reqd = (6*10*6*1)/(4*5*2) -6 = 9-6=3 persons, which is in options .... is not correct.

In this calculation you have not considered the work of double strength but men of double strength.
Normal work requires 6*10*6 = 360 man hours.
work of double strength will require 720 man hours.................
Total men required for doing the work of double strength( of 720 man hours ) in 4 days with an effort of 5 hours per day = 720/(4*5) = 36 men

Additional men reqd will be 36-6 =30 men.

Hope it is clear now.

Please excuse me for continuing discussion.

Your answer is only valid if all men now employed are of double strength and work is normal which only for 360 man hours.

According to 27.1.2010 question,

Six men do a piece of work in 10 days with an effort of 6 hours per day. How many extra men are required
for doing the work of double strength in 4 days with an effort of 5 hours per day.


Answer given is option 1...3 persons.

Means total 9 persons are required to do the work of double strength ( as clarified by Administrator).

As per clarificatin , the answer should be

(6*10*6*2)/(4*5*2) -6 = 18-6=12 persons
which is not in options.

I think there must be additional men of double strength in addition to 6 men of normal strength ( as pointed out by Dipin)

The difference of cube and square of a real number is equal to the difference of its square and itself.
Total number of such real numbers are ....

Sol given is 2.
based on explanation

x^3 - x^2 = x^2 - x
which is correct.

But please note according to given statement, there is one more equation that satisfies given condition which is

x^3 - x^2 = x - x^2

Here the question is about difference.

this equation gives one more value of x i.e. -1.
