Q:Robert purchased $3500 worth of US saving bonds. If bonds are sold in $50 or $100 denominations only, which of the following CANNOT be the number of US saving bonds that Robert purchased? | [
"20",
"80",
"27",
"70"
] | B | I started off with looking at the answer choices... 20-27-50 are in a tight range, so my guess was to look and rule out the bigger numbers.
The total amount is $3500. So with 80 bonds, each $50 = $4000 , we already exceed the $3500 limit. Hence E is the answer. | AquaRat_train |
A tap can fill a tank in 12 hours. After half the tank is filled three more similar taps are opened. What is the total time taken to fill the tank completely? | [
"13 hrs 30 mins",
"14 hrs 30 mins",
"16 hrs 30 mins",
"17 hrs 30 mins"
] | A | Time taken by one tap to fill the tank = 6 hrs.
Part filled by the taps in 1 hour = 4 * 1/12 = 1/3
Remaining part = 1 - 1/2 = 1/2
1/3 : 1/2 :: 1 : x
x = 1/2 * 1 * 3 = 1.5 hrs = 1 hrs 30 min
So, total time taken = 13 hrs 30 mins

In a 50-mile trip, the first 10 miles were completed at 50 mph. If the average speed for the whole trip was 60 mph, what was the average speed in the last 40 miles? | [
"900/17 mph",
"1000/17 mph",
"1200/19 mph",
"800/17 mph"
] | C | The time to complete the first 10 miles was (10 miles / 50 mph) = (1/5) hours.
The time to complete the whole trip was (50 miles / 60 mph) = (5/6) hours.
The time to complete the last 40 miles was (5/6) - (1/5) = (19/30) hours.
The average speed in the last 40 miles was (40 miles / (19/30) hours) = 1200/19 mph.

At a dinner party every two guests used a bowl of rice between them, every three guests used a bowl of dal between them and every four used a bowl of meat between them. There were altogether 65 dishes. How many guests were present at the party ? | [
"60",
"95",
"None of these",
"65"
] | A | no. of rice bowl=x
no. of dal bowl=y
no. of meat bowl=z
then, x+y+z=65(eq 1)
also, 2x=3y=4z
substituting value of y&z in terms of x in eq 1, x=30.
as 1 rice bowl is shared between 2 guests, therefore there are 60 guests...
