B)
let he can select a picnic spot =x m
.
. . x/40+x/30=8
x=137.1 m

Let distance = 'd'
Let us assume forward journey time is 't1'
Return journey time is 't2'
Given t1+t2=8
But time = distance / velocity
t1 = d/40
t2 = d/30
Therefore t1+t2 = d/40 + d/30 = 8
d=137.142

It fills at a rate of 2 (i.e) 10,20,40.... 1/16 is filled in 17hr. then it fills as 1/8,1/4,1/2,1.. Hence 17+1+1+1+1=21

One Part
velusara

Ans = R should be added with 50%If r is 2 parts S is 1 part i.e 2/1 = 1 or 1+1 = 2so if s increases by 25% of 1 then it is 1.25 + 1.25 = 2.5 that is r
Prashant202185

Since R= 2 parts and S = 1 parts so % of s = 1/3*100 = 33.33%Let x of r is added to make S to 25%then 1/(3+x)*100 = 25 => 75+25x=100 so x= 1 ans

4 km/hr from A to B = s1
8 km/hr from B to A = s2
Speed = Distance/Times1 = d1/t1
s2 = d2/t2
s1/s2 = t2/t1 We need t1/t2 so,
Answer ratio is 2:1

- 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
