Answer / prerna
A= 4B+ 5C
B= X+4Y+Z
C= 2X+6Y+Z
Given : X= 5 Kg, Y= 3Kg , Z= 8 Kg
To get 1400 Kg of A, We need 20B and 25C i.e 5A=1400 Kg =>
20B+25C
So,
20B= 20X + 80Y + 20Z
25C= 50X + 150Y + 25Z
On substituting values,
Totally 230 units of Y is needed which results in
690 Kg Anonymous

Answer / anil uttani
answer : a) 51
expalanation:
F(n-1) =1/(2-F(n))
therfore rearranging it we get
F(n)=2-(1/F(n-1))
F(n-1)>1
thus (1/F(n-1))<1
So F(n) = 2-x where x<1 always
thus 1<F(n)<2 always
so [F(n)]=1 always except F(1)=2
thus 2+49(1)=51
