Question 1
Answer
Question 1
What is the sum ( in RS) which when divided among X Y Z in the proportion 3:5:7 provides rupees 8000 more to Z then what it would have done to him when the proportion is 11 : 15 : 19?
180000
120000
175000
135000
Answer
Option= 180000
X:Y:Z
3: 5: 7
Z got 8000 more = 2 parts more than Y
If 2 parts = 8000
Then 1 part = 4000
Final ratio = 11: 15: 19 = 45 parts
45 x 4000 = Rs 180000

Question 4
Answer
Question 4
X is four times as efficient as Y in respect of doing a particular work. Working together they complete the work in 16 days. In how many days y working alone will be able to half the work?
80
20
40
60
Answer
Option = 40
Efficiency of X = 4a
Efficiency of Y = a
Time taken by both to complete a work = 16 days
a = 20
Hence X will do the work in 20 days
And Y will do the work in 80 days
Thus Y will do half of work in 40 days
Question 5
Answer
Question 5
If = 225 x 405, find the value of
27
81
125
25
Answer
Option = 27
Prime Factorization of 225 = 5 x 5 x 3 x 3
Prime Factorization of 405 = 3 x 3 x 3 x 3 x 5
5336 = 5X3Y
So X = 3 and Y = 6
Now, X2y – 3x = 32(6) – 3(3)
312 – 9 = 33 = 27

Question 8
Answer
Question 8
After purchasing two copies of the same book, X sold them respectively at 0.8 and 1.4 times their cost prices. What was the percentage gain earned or loss incurred by X?
10% loss
5% gain
10% gain
5% loss
Answer
Option = 10% gain
Let the C.P of each copy be Rs 100
ATQ one copy is sold at 0.8 x 100 = 80
One copy is sold at 1.4 x 100 = 140
Total money spent in buying the copies = Rs 200
Total money earned after selling the copies = Rs (80 + 140) = Rs 220
Total gain of Rs 20. Therefore gain% = 10%.

12
20
26
Answer
Option= 26 Answer
In given Question:-
Correct answer =5x and wrong answer=2y
Correct answer =4x and wrong answer= 1y
So,
5x -2y = 32
4x-2y =34——*2
Now
5x-2y =32
8x-4y=68
By solving
3x=36
x=12
Now to find ‘y’
5*12 -2y =32
60 -2y= 32
y=14
By adding x+y
12+24 =26
Questions in the test =26

let the number of data be n
so sum of data = mean * number of data
= 5 n
now 10 is subtracted to each data
so now sum becomes = 5n-10n =-5n
mean = sum of data /no. of data
=-5n/n = -5
so new mean becomes -5

A sum invested on simple interest grows to Rs 22500/- and Rs 25500/- is seven and nine years respectively. What is the rate percentage of the interest ?
7.5
9.6
12.5
13.5
Answer
Option= 12.5
Total Interest of two years= 25500-22500=3000
Interest of one year= 3000/2 = 1500
Total Interest = 9 * 1500 = 13500
Principle = 25500 – 13500 = 12000
R= I * 100/P *t
= 13500 *100/1200*9 = 12.5
