By investing in 1623% stock at 64, one earns Rs. 1600. The investment made is | [
"s. 6760",
"s. 6144",
"s. 7500",
"s. 9600"
] | B | Explanation :
Market Value = Rs.64
Face Value is not given and hence take it as Rs.100
16 2/3% of the face value = 50/3
ie, to earn 50/3, investment = Rs.64
Hence, to earn Rs.1600, investment needed = 64×3×1600/50=6144

John works full-time, 40 hours a week, selling cars at the local auto mall. His sales quota for a week is $20,000. How much does John have to sell per hour to make his sales quota? | [
"200",
"500",
"700",
"250"
] | B | There are 40 hours in a work week. If his quota is $20,000, then we simply divide 40 by $20,000.
20,000 / 40 = 500.
Therefore, John has to sell at least $500 per hour to meet his weekly quota of $20,000.
Thus, the correct answer is C. | AquaRat_train |

Jane and Thomas are among the 7 people from which a committee of 3 people is to be selected. How many different possible committees of 3 people can be selected from these 7 people if at least one of either Jane or Thomas is to be selected? | [
"40",
"30",
"20",
"25"
] | D | The total number of ways to choose 3 people from 7 is 7C3 = 35.
The number of committees without Jane or Thomas is 5C3 = 10.

The average speed of a train running at a speed of 30 km/hr during the first 100 kilometres, at 40 km/hr during the second 100 kilometres and at 50 km/hr during the last 100 kilometres is nearly? | [
"39.2 km/hr",
"38.3 km/hr",
"40.0 km/hr",
"None of these"
] | B | Time taken to cover first 100 kilometres = 100/3 = 3(1/3) hours
Time taken to cover second 100 kilometres =100/40 = 2(1/2) hours
Time take to cover last 100 kilometres = 100/2 = 2 hours
Total distance covered = 300 km.
Total time taken = 47/6 hours
Thus, average speed = 300/(47/6) = 38.3 km/hr.
