In a college, five different subjects viz Physics, Chem, Botany, Zoology and maths are taught on five different days of same week starting from Monday to Friday. Is Chemistry taught on Friday?
1) Two subjects are taught between Zoology and Maths.Maths is taught before Zoology. Chem is taught immediately next to the day when physics is taught. Botany is not taught on Friday?
2)Three lectures are taught between Botany and Zoology. Maths is taught immediately before Physics.

None of these

Consider the integers x,y,z . What is the min possi value of x^2 +y^2+z^2?


@erm said: @swetadhey even i understood this but go to know that statement 2 could only answer that isdue to the consideration of fractional nos. eg 15*2/3=10 hence even toh isliye man

@swetad said:Ans is (d) as anyone statement tells us that x is odd
hey even i understood this but go to know that statement 2 could only answer that is
eg 15*2/3=10 hence even toh isliye man


@peligro said:@erm bro the options are not clear.. is C option both taken together or both taken seperately??3 and 15 are odd so odd*odd = odd no so we can answer with both taken alone.
considering fractional nos.
eg 15*2/3=10
but i could understand how this is not true for 3*2/3=2
hence plz explain if understood


@erm said: is x is odd???I 3x is odd. II 15x is odd.a) statement I is sufficent to answer & not II b)statement II is sufficent to answer & not I c) both d) none of these
