we know that,
a+b+c+d+e+f+g+h+i=45-------------------(2)

subtracting equation (2) from (1),we get:
d+g=6

as the values are between 1-9,d and g can take following values:

1] (d,g)=(1,5)
2] (d,g)=(2,4)
3] (d,g)=(3,3)

but the 2nd option is not possible as a=4 and each alphabet holds a unique value.the 3rd option too,is not possible as d and g cannot have the same values.hence the correct answer is (d,g)=(1,5).

what is the question?

Sorry didnt follow...why is [5^2 * (125)^41]/124 = 25 * (1)^41 =25??

i gt 1 for ths .... u ??

HI all can sombeody solve this question

x^2+y^2+Z^2 =48 and X,Y and Z are positive real numbers
then what is the ratio of Max(X+Y+Z)/MIN(X+Y+Z)?

[mahajanankit86]

is the answer underoot(3)....

[ansh.python]

MAX when x=y=z
3x^2=48
x^2=16
x=4
implies x+y+z=12

Min when,x=y=0 and z=underroot(48 )
x+y+z=4*underoot(3)

ratio = underroot(3)

[ansh.python]

{25*(125)^41}/124 = [ 25*1]/124 =25

coz remainder is 1 when 125 is divided by 124
