Average

Average In this post, We will learn about average. Average of any collection of data is the sum of data divide by number of data. Average = (Sum of observations / Number of observations) Please write comments if you find anything incorrect, or you want to share more information about the topic discussed above. problems The arithmetic mean of x, y and z is 80, and that of x, y, z, u and v is 75, where u=(x+y)/2 and v=(y+z)/2. If x ≥ z, then the minimum possible value of x is (CAT 2018) As specified in the question mean of x and y and z is 80 x+y+z=3*80 mean of x, y, z,u,v is 75 x+y+z+u+v=75*5 2u=x+y 2v=y+z x+y+z+((x+y+y+z)/2)=75*5 y+3(x+y+z)=75*10 y=750-720 y=30 since x+y+z=240 y=30 so x+z=210 since x>=z so minimum value of x=210/2 = 105 Problem2: In first 5 inings sehwag has scored at average of 40. In sixth ining He had scored 52 what is His average after 6th ining. one simple approach is getting total score divided by no of inin...

SSC Practice Problem Solution

SSC Practice Problem Solution In this post, we will discuss solution of SSC Practice Problem . Question 1 The efficiency of (A + B) = 100/24 = (25/6)% The efficiency of (A + B + C) = 100/8 = (25/2)% The efficiency of C = 25/2 – 25/6 = (50/6)% Hence, C can alone finish this job in = 100/(50/6) = 12 days Answer: 12 days option (1) Question 2 Original price = Rs. 6000; Price after discount = 6000 – 1200 = Rs. 4800; Price after raising service contract = 4800 + 480 = Rs. 5280 Answer: Rs. 5280 option (2) Question 3 Suppose the received money by A, B, and C is respectively 5x, 6x, and 9x. 5x = 450; => x = 90; Hence, the total money = 20x = 20*90 = Rs. 1800; Answer: Rs. 1800 option (2) Question 4 Suppose the Cost price of the bag= Rs. x; Hence, x + 0.15x = 230; => x = Rs. 200; Selling price after selling on 20% = 200 + 20% of 200 = Rs. 240 Answer: Rs. 240 option (3) Question 5 The required percentage ...

Permutations and Combination

Permutations and Combination Permutations and Combination is one section of the CAT Quantitative Aptitude which needs the least number of formulae and the maximum amount of logic. This topic is asked in almost every competitive exam, so don’t take the risk of avoiding it. After reading this article you will be familiar with Permutation and Combination. Definition of Permutation : Permutation is defined as the arrangement of r things that can be done out of total n things. Formula of Permutation Permutation is denoted by nPr it is equal to n!/(n-r)! Defination of Combination: Combination is defined as selection of r things that can be done out of total n things. Formula of Combination Combination is denoted nCr it is equal to n!/r!(n-r)! Fundamental principle of counting Product Rule: If an activity A can be done in “m” ways and an another activity “B” can be done in “n” ways, A and B together can be done in “m x n” ways Example: How ma...

Percentage

Percentage In this post, we will learn about percentage . Percentage One percent (1%) means 1 per 100. Fifty percent (50%) means half of total. Hundred percent (100%) means full or 100 out of 100 or 1000 out of 1000. Two hundred percent (200%) means twice of original. for example if your salary is 12 Lakh and change your job and you salary become 36 Lakh in this case you salary increased by (36 - 12) = 24 Lakh means twice of original means your salary increased by 200 %. Calculate Percentage Example: Calculate 25% of 80 100% of 80 = 80 1% of 80 = (80/100) 25% of 80 = (80/100)x25 Shortcut: X percentage of Y = (Y x X)/100 If only 10 of the 200 apples are bad, what percent is that? In 200 apple 10 are bad In 1 apple (10/200) will be bad In 100 apple (10/200)x100 = 5% will be be bad Shortcut: X is k percentage of Y means X = (k*y)/100 Please write comments if you find anything incorrect, or you...
