Its simple, It takes one hour to reach and hence 2 + 1 is 3. Its meets the auto by 2 so it takes one more hour to reach hence 3 is the answer.

for 25 members = 25*70=1750 for 50 members = 50*60=3000 therefore 3000-1750=1250 so, 1750-1250=500 this 5oo is common. therefore 1250 for every 25 members therfore to check for 25 members ...

Let fixed cost=a, variable cost=kWe can write a+25k=70*25=1750a+50k=3000We get k=50then a=3000-(50*25)=500Charge per head= (500+100*50)/100 = 55

NEVER!If you are deciding the numbers of arguments on the basis of size of int in 32 bit compiler, it should be 2^31-1. that is almost square of 32767.And The memory allocated to argv is from RAM. SO do you really think compiler allocates memory holding 2^31-1 strings of any size!

There are a total of 150 weights. Let the number of 1 Kg weights be 'x'. Then the number of 2 Kg weights is '150 - x'. The sum of the weights is 260 Kg. ie [x * 1 + (150 - x) * 2] = 260. By solving this you will get 'x' as 40.

Guys the formula is?(2^n)-1?n==>2,4,8,16, bit memory. this gives the max no and by reducing the max no we get largest prime no.
