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

A car is filled with four and half gallons of oil for full round trip. Fuel is taken 1/4 gallon more in going than coming. What is the fuel consumed in coming up?
Before the trip, car is filled with = 4 ½ gallon of oil.Let ‘X’ be the quantity of fuel consumed for the trip in one direction The fuel consumed while going = X + ¼ The fuel consumed while coming = XTherefore, the fuel consumed for the trip = (X + ¼) + X = 4 ½ 2X + ¼ = 4 ½ => 2X = 4 ½ - ¼ => 2X = 4 ¼ => X= 2 1/8 . approxTherefore the fuel consumed while coming = 2.125 gallon

Total fuel=4.5 gallons
let amount of fuel for coming=x so a.t.q amonut of fuel for going = x+ x/4=5x/4.
so 5x/4+xsriram_v

2.125 is not the right answer we need to add 1/4 to that to get the fuel consumed while coming upthe right ans is 2.125+0.25=2.375

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

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

5 m/sec

When we convert 25 m/sec into km/ hour we get 90 km/hour so the difference in their speeds would be
90-72=18 km/hour.. or 5 m/sec (18 km/hour converted in m/sec )jeevan ambati

If the speed of B is converted in Km/hour it would be 80 km/hour... so the difference would be 80-72=8 km/hour or 8 km/hour

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
