200>100 true first the answer is 1 but compiler jumps to x=50;
so the final value is 50

what is the probability that 4 numbers selected from 1 to 40 are not consecutive
rajeswarisvgrnthn
- Aug 30th, 2010
From 1 to 40 there are 37 possible combinations of 4 consecutive numbers.
Total number of possible combinations= 40C4.
Probability of outcome to be consecutive = 37/(40C4)= 1/2470
Probability of outcome not to be consecutive = 1-(1/2470)= 2469/2470
tiru5796

Ans: (40-4+1)
C = no. of combinations
4
Total no. of chances= 37
Probability=37/37C4

Tree problem
A tree grows only 3/5 as fast as the one beside it. In four years the combined growth of the two trees is eight feet. How much does the shorter tree grow in two years? (a) Less than 2 feet (b) 2feet (c) 2 1/2 feet (d) 3 feet (e) more than 3 feet.
ga_nesh
- May 25th, 2008
Even after 4 years the ratio remains d same..therefore:x+(3/5)x=8thus x=5therefore the height of the shorter tree is 3 feet after FOUR years..therefore after TWO years the heght will be 1.5 ft..

Program Memory Occupied
The size of a program is N. And the memory occupied by the program is given by M = square root of 100N. If the size of the program is increased by 1% then how much memory now occupied?
santhakumar.mit
- Aug 28th, 2010
NOW N=N+N/100=101N/100M=SR OF 100N=>SO SR OF 100*101/100ans is SR OF 101N
SpandanaMohan
- May 21st, 2008
The memory size depends on the size of the program...If the program size is increased by 1%, then the memory size also changes according to size of the pgm...The new size of the program is n+n/100...and the size of memory is square root of 100(n+n/100)....

Counterfeit Coin
In 80 coins 1 coin is counterfeit which is minimum no. of weighings to find out counterfeit coin.
santhakumar.mit
- Aug 28th, 2010
80 coins divided as 27 27 and 26 coins..
then 27 is divided as 9 9 9 or 26 is divided as 9 9 8
then 9 is divided as 3 3 3 or 8 as 3 3 2 and
finally 3 as 1 1 1 or 2 as 1 1
so finally minimum number of weighing required 4
This one is correct one

bus
A non stop bus to Amritsar overtakes an auto also moving towards Amritsar at 10 am. The bus reaches Amritsar at 12.30 pm and starts on the return journey after 1 hr. On the way back it meets the auto at 2 pm. At what time the auto will reach Amritsar?
santhakumar.mit
- Aug 28th, 2010
Totally bus takes 2.30hrs to reach the Amristar.
So 1/5 of i.e 30 mins reach the one place where it met auto.
That means 4/5 of this travel by bus is 2hrs and auto is 4hrs
so2:4::1/2:x
2/4=1/2x
4x=4
x=1
so auto will reach Amirstar at 1hr.

organizing the home can be perceived as conferring power so large numbers of women are unwilling to let go of chores, even when they have careers. a survey found that, out of 65 new marriages not one single wife expected her husband to share work equally. according to the family policy studies center 81% working wives return home to do all the cooking. The average male has nearly half as much more free time at weekends than his wife and the typical new father spends just 37 seconds a day talking to his baby.

The purpose of the proposed law requiring a doctor's prescription
The purpose of the proposed law requiring a doctor's prescription for obtaining hypodermic needles is to lower the incidence of drug-related deaths, both accidental and intentional, involving hypodermic needles. But even knitting needles can be lethal if they fall into the wrong hands; yet everyone would agree that imposing legal restrictions on obtaining knitting needles would be preposterous. Hence...

The answer should be 33.5 As there are two equation L+H=100andL=1/3 + 1/2(H)so we getL= 1/3 + 1/2(L-100)Which gives L= 33.5 approx.
