hi aspirant i saw this sentence earlier, and made it wrong picking C. C is wrong because tences here are not proper judge overturned the ban (past simple).....that it violates(present simple) laws that allowed (past simple) thus, ban now violates the laws that are no longer in use, as laws were in ...

one more way to solve st 2, but in essence the same as that of can x=10a+b y=10a+m. where a is the same tens digit for x and y and b and m are digits 10a+b+10a+m=77 20a+b+m=77, here a can`t 4 as 20*4=80 that is more than 77, and here a can`t 2 as 20*2=40, and themax value of m+b=18, (40+18=56<77) so...

if n^2<1/100. n^2-(1/10)^2<0
(n-1/10)(n+1/10)<0, this inequality is valid for -1/10<n<1/10. but as n<0. the resulting is
-1/10<n<0

here i got B, my thinking when n is divided by 2 it can give only two remaiders 1 or 0, for remaider 1 n is odd, and for remaider 0 (n is divisible by 2) n is even.so the problem asks does n odd or even (1)n=5k+(2m+1), here k is integer, and (2m+1)-odd remaider,(note m here can equal 0 or 1 only) so...

it will be great next time to hide answer is spoiler is c even if c and d are integers (1) c(d+1)=cd+c=even, possible cases are even(c)*even(d)+even(c)=even here c is even odd(c)*odd(d)+odd(c)=odd+odd=even, here c is odd, insuff (1) (c+2)(d+4)=even cd+4c+2d+8=even the value of 4c+2d+8 does not matte...

is |x|=y-z
if x>=0.then x=y-z,
if x<0, then x=-(y-z)=z-y
(1) x=z-y, but says nothing about x i mean +ve or -ve. insuff
(2)x<0 but no info about y-z
together
x<0 and x=z-y. so |x|=y-z suff

i`ll try
does 1/p>r/(r^2+2). or does
(r^2+2)/p>r
(1)p=r=x
(x^2+2)/x=x+(2/x) vs x, we can cancel x from both parts and arrive does 2/x>0 it is possible if x=p=r>0
but we not given sign
so 1 st insuff
(2) second insuff as it does not mention p
both: p=r=x>0 so 2/x>0 so suff

for sure you can multiply by (r^2+2) as it is +ve
but you can`t multiply by P is it can be +ve or -ve, and if p is -ve you must reverse the sign of the inequality

n^2<1/100, follows that -1/10<n<0
n>-1/10
(n)^(-1)<(-1/10)^(-1), n^(-1)=1/n, (-1/10)^(-1)=-10. we reverse the sign of the inequality since for example if 2<3, then 1/2>1/3, or -3<-2, then -1/3>-1/2 so
1/n<-10

rate*time=distance. rate*time=400,time=400/rate, so we need to find rate (1) insuff as it says only about speed at the first 200 km (2)(rate+20)*(time-1)=400,1 st equation and second:time*rate=400, we have two unknows and two equations, so rate can be found solving quadratic equation (i hope one of ...

if r and q are +ve integers are they both greater than n (1) p-q>n.insuff as can be seen on examples p=6,q=2,n=3 p-q=6-2=4>3, but q<n, 2<3 p=6.q=2.n=1 p-q=6-2=4>1, and n is less that both p and q (2) q>p no info about n also insuff both p-q>n q>p sum both p-q+q>n+p and cancel all but n and left with...

one of ideas here is to plug numbers total income of the family=100 mr lee income=0,6*100=60 income of the rest of the family=40 (40+60=100) in june mr lee income increased by 20%=60*1.2=72 the income of the rest is the same=40 so total family income in june=40+72=112 the part of mr lee income in to...

squares of the integer till 100 are
1,4,9,16,25,36,49,64,81
(1) says that n is even.possible n are 4,16,36,64, as the value is not fixed, ont suff
(2)cubes till 100 are
1,8,27,64,but only one of them is also square of the integer it is 64=8^2=4^3. so n=64 suff
