why such hard calculations its simple - 0 2 4 6 8 so av appx - 4 because of even space , now std deviation - 4 as 8-4 = 4 & 4-0=4 now add 4 4 to each deviation will be with in the range so 4 4 should answer try to understand the logic of ST deviation not just formula and heavy calculations

what the question - A+B square or 2. (A+B) in case two OA=E in case one OA=C

Hi

IMO - E ,
as it clear that A, B , D gone just by seeing two options

so We left with C or E , now
combine - equation - A^2-2.A-15=0 give a= 5 or 3 , so b= -3 or -5

so( A+B ).2= +16 or -16

hence E

Can i try to elaborate little simpler -

2, 22, 222 up to 50 terms ,

so unit digit - 50X 2 = 100 for sure
10 will carry forward
next 2 X 49 = ... 8

so ,,,8 + 10 = always 8 on right side

so ans must be 8

IMO - B

can i post a simple approach to answer this tricky question


its says no guard for 2 consecutive day

so every day we left with balance 3 guys , just before day ,,,hope it clears and we skip that C2 c 5 equations

If y=−m2, which of the following must be true? I) y is

If y=−m2, which of the following must be true?

I) y is negative.

II) m is non-negative.

III) If m is negative then y is negative.

Is x > y? (1) √x > y (2) x3 > y

Is x > y? (1) √x > y (2) x3 > y
