If a man buys 25 lollipops for $100 and sold them for $3 dollars determine his loss.
[ "$ 25", "$ 60", "$ 50", "$ 35" ]
A
Cost of 25 lollipops = $90 Sold each lollipop for $3 So he sold 25 lollipops for $(25 × 3) = $75 Loss = $(100 – 75) = $25 Therefore, loss = $ 25. Answer:E

A number when divided by 342 gives a remainder 47. When the same number if it divided by 19, what would be the remainder ?
[ "5", "11", "9", "1" ]
C
On dividing the given number by 342, let k be the quotient and 47 as remainder. Then, number – 342k + 47 = (19 x 18k + 19 x 2 + 9) = 19 (18k + 2) + 9. The given number when divided by 19, gives (18k + 2) as quotient and 9 as remainder. ANSWER D

A certain car can travel 40 minutes on a gallon of gasoline at 60 miles per hour. If the car had started with a full tank and had 12 gallons of gasoline left in its tank at the end, then what percent of the tank was used to travel 80 miles at 60 mph?
[ "20%", "25%", "15%", "14%" ]
D
Total time for travelling 80 miles @ 60 mph = 80/60 = 4/3 hour = 80 minutes. Given, the car uses 1 gallon for every 40 minutes of driving @ 60 mph. Thus in 80 minutes it will use = 2 gallons. Thus, full tank = 2+12= 14 gallons ---> 2/14= 14% of the fuel used. E is the correct answer.

Two trains of length 100 m and 200 m are 70 m apart. They start moving towards each other on parallel tracks, at speeds 54 kmph and 72 kmph. After how much time will the trains meet?
[ "53/2 sec", "2 sec", "20/7 sec", "32/3 sec" ]
B
They are moving in opposite directions, relative speed is equal to the sum of their speeds. Relative speed = (54 + 72)*5/18 = 7*5 = 35 mps. The time required = d/s = 70/35 = 2 sec. Answer:a

A
Let L be the original length and let W be the original width. The original area was L*W. The new area is 0.9W*1.2L = (0.9)(1.2)L*W = 1.08*L*W The answer is C.
