A shipping clerk has five boxes of different but unknown weights each weighing less than 100 kg. The clerk weighs the boxes in pairs. The weights obtained are 110, 112, 113, 114, 115, 116, 117, 118, 120 and 121 kg. What is the weight, in kg, of the heaviest box ?
[ "Can't be determined", "60", "None", "61" ]
D
Explanation : Two boxes are selected at at time and weighed together. Thus, the selection order does not matter and selecting box 1 and then box 2 is the same as selecting box 2 and then box 1. So this is a combination problem. 2 boxes can be selected from 5 boxes in 5C2 ways, i.e. 10 ways. The given list of weighings ...

P alone can complete a piece of work in 6 days. Work done by Q alone in one day is equal to one-third of the work done by P alone in one day. In how many days can the work be completed if P and Q work together?
[ "6 (3/4) days", "6 (1/4) days", "9 (3/4) days", "8 (3/4) days" ]
A
Work done by P alone in one day = 1/9th of the total work done by Q alone in one day = 1/3(of that done by P in one day) = 1/3(1/9 of the total) = 1/27 of the total. Work done by P and Q, working together in one day = 1/9 + 1/27 = 4/27 of the total They would take 27/4 days = 6 (3/4) days to complete the work working t...

What is the radius, in feet, of the pillar with the largest volume that could still fit...
[ "6", "4", "12", "2" ]
A
We can find the radius of all the three cases of cylinders. The only crux to find the answer faster is that: Voulme is pi*r^2*h. The volume is a function of r^2. so r has to be the highest to find the largest volume. So r=6 for the surface 8*12 face. Volume = 216pi Answer C

B
As cars are moving in opposite directions their speeds will be added. So their relative speeds: 60+40 = 100 mph Total distance to be covered = 500 miles. Time taken would be: 500 miles/100 mph = 5 hours E is the answer.

Two spinning machines A and B can together produce 3,00,000 m of cloth in 10 hour, if machine B alone can produce the same amount of cloth in 15 hour, then how much cloth can machine A produce alone in 10 hour?
[ "1,50,000 m", "None of these", "50,000 m", "1,00,000 m" ]
D
Explanation : According to the question, machines A and B together produces 30,000 m of cloth in 1 hour. And,machine B alone can produce 20,000 m cloth in 1 hour. So, Machine A can produce (30,000 - 20,000) = 10,000 m cloth in 1 hour. Hence, in 10 hour Machine A can produce 10 x 10,000 = 1,00,000 m of cloth. Answer : B
