4*4!
A Small confectioner bought a certain number of pastries flavoured Pineapple, Mango and Black-forest from the bakery, giving for each pastry as many rupees as there were party of that kind. altogether. he bought 23 pastries and spent Rs. 211; find the number of each kind of pastry that he bought, if mango pastry are cheaper than Pineapple pastry and dearer than black-forest pastry.

black forest-3,mango-9,pineapple-11??

Yumm! black-forest pastry 
:P
:Pa + b + c = 23
a^2 + b^2 + c^2 = 211 where b less than c and b greater than a
@Shray14 said:Kaise kiya bro??
P+M+BF=23
P^2+M^2+BF^2=211
P>M>BF(given condition)...3,9,11 satisfy both the eqn
@Shray14 said:Kaise kiya bro??
solve equations.
let the quantity be a,b,c for black forest, mango and pine-apple
acc to question
a+b+c=23
a^2+b^2+c^2=211
solve the above equation.
@Brooklyn said:appraoch ??
as it is given in d ques.....{giving for each pastry as many rupees as there were party of that kind.}....my inference frm dis......no. of pastry he bought of a type= price of a pastry of that type...(no sure about my inference whether it is ryt or rong....lets see d OA)
X+Y+Z=23
X^2 + Y^2 + Z^2=211
only 3, 9 ,11 satisfies abuv eqs.
frm last lyn of d ques....pine=11,man=9,BF=3....

sir why u have squared the 2nd equation??
@Shray14 said:sir why u have squared the 2nd equation??
cost of each is equal to its number of objects

Bhai agar 3 pastries hai and on 3 ki hai to 3 kitne ko hongi ?
3^2 ?
Similarly for others ..

Are han yar..thanks a tonn
i have a question which covers a basic concept
what is the lcm of (15,1.5,1.5555555555......infinite times)
hcf(15,1.5,1.55555555555555555.......infinite times)
