A work is done by two people in 24 min. one of them can do this work a lonely in 40 min. how much time required to do the same work for the second person.
In 1 minute (A+B) can do 1/24 work. A alone can 1/40 work in 1 minuteB alone can do in 1 minute = (A+B)’s – A’s = 1/24 – 1/40 = 1/60 workTherefore, b can do the same work in = 60 min

A person was fined for exceeding the speed limit by 10mph. Another person was also fined for exceeding the same speed limit by twice the same. If the second person was traveling at a speed of 35 mph, find the speed limit.
Let ‘x’ be the speed limit. Person ‘A’ was fined for exceeding the speed limit by = 10mphPerson ‘B’ was fined for exceeding the speed limit by = twice of ‘A’ => 2*10mph=20mphgiven that the second person was traveling at the speed of 35mph => 35mph – 20mph = 15mphTherefore the speed limit is =15 mph

ok let us suppose 100 kg of fuel is being wasted.. if i use the A then 30 kg will be saved n 70 kg will be wasted. now if i bring in B it will save 40% of 70 n (70*0.6)=42 kg will be wasted. Now if i incorporate C then it will save 10%of 42 i.e..,(42*0.9) 37.8 kg will be wasted... so 100-37.8=62.2 kg will be saved.. so ans is 62.2%

Assume total =100 then 30% = 70, 40% reduction = 3/5 and 10% reduction = 9/10. Therefore total reduction = 70X(3/5)X(9/10) = 37.8 therefore ans = 100 - 37.8 = 62.2

Total time taken by it is following :1.5 (to reach at destination) + 0.5 ( talking halt at station) + 1 (return with 50% speed)so the total time taken by it is 3 hrcurrent time is 8.00 a.m + 3 hr = 11 a.m.So 11 a.m. is the right answer

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.

B)
let he can select a picnic spot =x m
.
. . x/40+x/30=8
x=137.1 m
so ans is b.rajendraprasad349
- Aug 27th, 2010
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

If 8 men can reap 80 hectares in 24 days, then how many hectares can 36 men reap in 30 days?

Editorial / Best Answer
sanjeev yadav- Member Since Dec-2007 | Jan 9th, 2008
By Direct approach :
more men,more hectares
moredays,more hectares
so,
8 / 36 : 24 / 30 = 80 / x
x = (36 x 30 x 80) / (8 x 24)
450
