hi,

I would like to differ on this
My answer would be both D and E

a=8 b=4

a)a/2=8/2=4
b)b/2=4/2=2
c)(a+b)/2=(8+4)/2=12/2=6
d)(a+2)/2=(8+2)/2=10/2=5(odd)
e)(b+2)/2=(4+2)/2=6/2=3(odd)

Hope u agree with me

The general procedure to calculate it is, if jan 1 2002 comes on wed, jan 1 2003 will come on thursday if some leal yaer comes in-between then add two days. so going by that June 25 1982 fell on Friday so June 25th 1987 should be, June 25th 1982 - Friday June25th 1983 - Saturday June 25th 1984 - Mon...

i guess some imaginary no "i" should have accompanied the answer choices

For 4 digit code , since no codition mentioned for repetition,

26^4

For 5 digit code,
26 ^5

Since it is "OR"

26^4+26^5 = 26^4(1+26)
= 26^4(27)

answer : 27(26^4)

here "even though" clearlyb states the meaning "inspite of"
while doesn't convey the same meaning is wht i feel

hai

i think there is no "specially serious pollutant" or "not so special serious pollutants"
that makes a difference
