Please note that by definition the term even and odd is confined to integers only. Definition of even = any number that is a factor of 2 or when the given number is divided by 2, we get an integer. Consider 2.6. This number is not a factor of 2. 2.6 divided by 2 will not give any integer. However, t...

i wonder how stmt. I is sufficient!
I: x^2+A>2x
so, x = -2 ; A = 1 & x = -2; A=-1. In both cases the inequality holds but A is positive in former and negative in latter.

Both the statements, individually, implies that the number of black socks is 0 or 1.
so Black socks is at max 1.
so the probablity of drawing a second socks is always 0.
P(B1)=Probability of drawing first black socks = 1/8.
P(B2)=Probability of drawing second black socks = 0/7
P(B1)*P(B2) = 0

i think there is a subtle meaning difference in both the sentences:
C: oil reserves are exhausted - This means that the oil reserve will exhaust after its prolong usage.
D: exhausting its oil reserves - This means that the state delibrately wants to exhaust its oil reserves.

D is finite, but has two line segment.
x > 0: 2<= x< =5
x < 0: -2>= x >= -5
Since, above two intervals do not have any common point, they will be represent different segments.
I don't think we can say anything about quadrants, because value of Y is unknown.

we need the value of:
2*3*5*7*11*13*17*19
=210*(10+1)*(10+3)*(10+7)*(10+9)....did a quick multiplication till the point it is easy and got 210.
=210*10*10*10*10 *(2+4+8+10)...took 10 common
=210*24*10*10*10*10
=210 has two 10s and 24 has one 10.
sp total 10s = 2+1+1+1+1+1 = 7

let's start with smallest two digit positive integer.
it wud be 64 = 2^6.---(i)
one more we can get by: 2^5*3...(ii).
trying to find one more: 2^4*3^2 = but this is three digit.
so we were able to find only 2.
