A boy was asked to find 7/9 of a number. But he divided the number by 7/9, Thus he got 32 more than the correct answer. Find the number. | [
"62",
"63",
"34",
"61"
] | B | Explanation:
Let the number be x.
x/7/9 = 9x/7 = 32 + y
Actualy he should do 7x/9 = y
y = (9x/7) - 32
y = (9x - 224)/7
(9x - 224)/7 = 7x/9
81x - 2016 = 49x
81x - 49x = 2016
32x = 2016
x = 63

A container holds 4 quarts of milk and 4 quarts of water. How many quarts of water must be added to the container to create a mixture that is 3 parts milk to 5 parts water by volume? | [
"10/3",
"7/3",
"8/3",
"4/3"
] | C | An alternate to the alligation method is the more direct/algebraic method:
Let x be the amount of water to be added.
New total amount of water = 4+x
Total amount of milk= 4
New total = 4+4+x=8+x
Final ratio required (for water) = 5/(5+3)=5/8
Thus, (4+x)/(8+x) = 5/8 --> solving for x you get x = 8/3.

"25C5 * 10! *4!",
"20C4 * 11! * 7!",
"21C2 * 10! *3!",

] | B | 12 people can be selected from 20 people in 20C12 ways.
Remaining 8 people can be selected from 8 people in 8C8 ways.
Now, arranging 12 people on a round table = (12-1) ! = 11!
Arranging 8 people on a round table = (8-1) ! = 7!
Hence, total number of ways = 20C12 * 11! * 8C8 * 7!

A monkey climbs 30 feet at the beginning of each hour and rests for a while when he slips back 20 feet before he again starts climbing in the beginning of the next hour. If he begins his ascent at 9.00 a.m., at what time will he first touch a flag at 120 feet from the ground? | [
"6 p.m.",
"None of these",
"5 p.m.",
"7 p.m."

Net ascent of the monkey in 1 hour = (30 - 20) feet = 10 feet.
So, the monkey ascends 90 feet in 9 hours i.e. till 6 p.m.
Clearly, in the next 1 hour i.e. till 7 p.m. the monkey ascends remaining 30 feet to touch the flag.

"156,789",
"192,389",
"188,889",
"275,889"
] | C | 1-9=>1*9 digits
10-99=>2*90=180 (numbers between 10-99 is 90 where each has 2 digits)
100-999=>3*900=2700
1000-9999=>4*9000 = 36,000
10000-39999=>5*30,000 = 150,000

Solution 1
Pipes A and B can fill the tank in 5 and 6 hours respectively. Therefore,
part filled by pipe A in 1 hour =1/5
part filled by pipe B in 1 hour =1/6
Pipe C can empty the tank in 12 hours. Therefore,

The interest on Rs. 750 for 2 years is the same as the true discount on Rs. 960 due 2 years hence. If the rate of interest is the same in both cases, it is: | [
"54%",
"11%",
"14%",
"94%"
] | C | S.I. on Rs. 750 = T.D. on Rs. 960.
This means P.W. of Rs. 960 due 2 years hence is Rs. 750.
T.D. = Rs. (960 - 750) = Rs. 210.
Thus, S.I. on R.s 750 for 2 years is Rs. 210.
Rate = 100 x 210 % = 14%
