1)A,B,C can complete a work in 6,8,12 days respectively. All three together completed on job for an amount 2340/-. Then what will be C âŽâĒs share in that amount?
1)What is value at ? symbol in the series 1,?,4,7,7,8,10,9
2)No. of triangles in octagon?
2)No. of triangles in octagon?
@krum thanks,got it.
@pyashraj ur diagram is clear enough for me to understand,thanks for taking ur time to draw and upload the pic.
will ask u if i have further doubt on the same question ð

3)A rice seller has 2 varieties of rice rs20/kg, rs24/kg, rs30/kg. He mixed all the three and sells at 30/kg with 20% profit on it. If third type is 2kgs in the mixture then what is the amount of 2nd type in that mixture?
4)If feb 27th 2003 is Thursday then what is 27th feb 1603???

1/12/(1/6+1/8+1/12)*2340 = 520

3) is this question correct ?
4) (304+96*2)mod7 = 6
so wednesday ?
4) (304+96*2)mod7 = 6
so wednesday ?
@sumit99
Let x kg be bought of Type I rice(20/kg) and y kg be bought of Type II rice(24/kg)..
Now, SP of the Mixture= 30/kg..Thus, Original CP of the mixture= 30/1.2 = 25/kg..
Now, 20x + 24y + 60/(x+y+2) = 25
=> 5x + y =10..(i)
Only Possible +ve Integral Soln of the eqn(i) is x=1, y=5
Thus, Type II rice is 5 kg in the mixture..

@nole said:one more question from XAT.at the centre of a city's municipal park,there is a large circular pool.A fish is released in the water at the edge of the pool.The fish swims north for 300 feet before it hits the edge of the pool.It then returns east and swims for 400 feet before hitting the edge again.What is the area of the pool ?I marked as "cannot be answered from the given data " which was wrong answer. answer was 62,500pi.
circumradius=abc/4*area
300*400*500*2/4*300*400
250
pie(250)^2

Can you please elaborate ?
It will be really helpful.

A teacher wanted to adminster a multiple choice(each question having six choices) based quiz of high difficulty level to a class of sixty students.The quiz had sixty questions.The probability of selecting the correct answer for a good and brilliant student was 0.2 and 0.25 respectively.All the students were seated serially in 10 rows and 6 columns.
q) three good students were seated next to each other.What is the probability of them having the same incorrect choice for four consecutive questions ?
i did it like
to get one incorrect answer, probabilty is 1/5
so all INCORRECT for one student is 1/5*1/5*1/5*1/5
so overall for 3 students (1/5*1/5*1/5*1/5)^3 but it is not in options.where did i go wrong ?
answer is 4/3125.
