x^3*y^4 = 2000. What is y?
x is an integer
y is an integer
Is it a PS question? Or is it DS ?
if it is PS,
2000= 2* 10* 10* 10=> 2* 5*2*5*2*5*2 => 5^3 * 2^4 .
Seems to be the only possibility when both x and y are integers.
If it is DS =>
Stt1 : x is an integer => x could be 10 =>
and => x^3 = 1000 => y is not an integer but y=2^(1/4)
but, x = 5 => y = 2
SO, Y cannot be found.
Statement 2 => y is an integer => could be several values again as X is not an integer.
Both togehter STT1 + STT2 => x=5 and y=2 is the only possibility.
So, IMO - C.
