Marge has Z candies, where Z is an integer such that 20 < Z< 50. If Marge divides the candies equally among 5 children, she will have 2 candies remaining. If she divides the candies among 6 children, she will have 1 candy remaining. How many candies will remain if she divides the candies among 7 children? | [
"3",
"2",
"1",
"0"
] | B | If Marge divides the candies equally among 5 children, she will have 2 candies remaining.
This tells us that the candies are of 5x + 2 type and so 22, 27, 32, 37, 42, or 47
If she divides the candies among 6 children, she will have 1 candy remaining.
this tells us it is if 6x+1 type and so 25, 31, 37, 43, or 49

A certain sum becomes Rs. 20720 in four years and 24080 in six years at simple interest. Find sum and rate of interest? | [
"12%",
"82%",
"13%",
"28%"
] | A | Let the interest for one year be x.
As amount = Principal + Interest, we have
P + 4x = 20720 --- (1) ; P + 6x = 24080 --- (2)
Solving the equations (1) and (2), we can get
P = Rs. 14000 and x = Rs. 1680
Interest for one year on Rs. 14000 is Rs. 1680
So, R = (100 * 1680)/(14000 * 1) = 12% p.a.

Eleven bags are bought for Rs.1000 and sold at 10 for Rs.1200. What is the gain or loss in percentage? | [
"22%",
"20%",
"None of these",
"25%"
] | A | Explanation:
As selling price is Rs.1200 for 10 bags, each bag is sold at Rs.120.
Hence, the profit is Rs.100 after selling 10 bags plus the selling price of 1 bag = 100 + 120 = Rs.220.
%profit = 220/1000 *100
= 22%

If a, b, and c are integers and a*b^2/c is a positive even integer, which of the following must be true?
I. c is even
II. ab > 4
III. ab is even | [
"I and II",
"III only",
"I only",
"I, II, and III"
] | B | Two ways this can happen: 1- Even/ Even= Even or 2- Even/Odd= Even
So Ab MUST be even, with either A or B being even, Ab does not have to be positive, as B could be negative and once it is raised to 2 it becomes positive again, and of course, C could be Odd or Even as described above.

A boat crossed a lake from East to West at the speed of 5 km/h, entered a river and covered twice as much distance going upstream at 4 km/h. It then turned around and stopped at the south shore of the lake. If it averaged 3.6 km/h that day, what was its approximate downstream speed? | [
"5",
"7",
"6",
"4"
] | C | One way of solving this is:
Speed of boat on still water (lake)=5kmph
Speed upstream = 4kmph = speed in still water - speed of river => speed of river = 1kmph
=>Speed downstream = speed in still water + speed of river = 5+1 =6kmph
