Question 2
Answer
Explanation
Question 2
Let x be the least number which when divided by 12,15,18,20,27 and 30, the remainder in each case is 1 and x is a multiple of 47. The sum of the digits of x is:
a. 13
b. 11
c. 9
d. 10
Answer
d. 10
Explanation
LCM of 12,15,18,20,27, 30 is 540
Number should be divisible by 47 if we multiply k by 540 and add 1 then the number is divisible
by 47
540k + 1/ 47
Put value of k as 1,2
For k=2
540 * 2 +1 = 1081 which is divisible by 47
1081/47=23
So the digit is 1081
Addition of digits = 10

12.5% discount on List Price.
Selling Price = 87.5x
Let Cost Price = y
y*112/100 = 87.5x
=> y = 78.125x
If given 25% discount Selling Price = 75x
%Loss = (78.125x-75x)*100 / 75x = 4%

Question 14
Answer
Explanation
Question 14
In a competitive exam, 5 marks are awarded for every correct answer and for every wrong answer, 2 marks are deducted. Sathwik and 32 marks in this examination. If 4 marks has been awarded for each correct answer and 1 mark had been deducted for each incorrect answer, Sathwik would have scored 34 marks. If Sathwik attempted all the questions, how many questions were there in the test?
A) 20
B) 14
C) 12
D) 26
Answer
D) 26
Explanation
Let Sathwik answered x right questions and y wrong questions.
Then total number of questions = x+y
The marks Sathwik scores in the examination = 5x-2y
5x-2y = 32 …i
Now if 4 marks are awarded for every correct answer and for every wrong answer, 1 marks are deducted.
The marks Sathwik scores in the examination = 4x-y
4x-y = 34 …ii
Now Solving Equation (i) & Equation (ii) ->
x=12, y=14
Total questions = (12+14) = 26

Question 18
What is the sum (in Rs) which, when divided among X, Y, Z in the proportion 3 : 5 : 7 provided Rs. 8000 more to Z than what it would have done to him when the proportion is 11 : 15 : 19?
A) 120000
B) 180000
C) 135000
D) 175000
Answer
B) 180000
Explanation
Let, The Sum = x
For Initial Distribution, The dividend for z=7x/(7+3+5)=7x/15
For New Distribution, The dividend for z=19x/(19+11+15)=19x/45
=> 7x/15–19x/45=8000
=> 2x = 8000*45
=> x = 180000
