Simplification

Understanding BODMAS:
Though this area may have less of direct questions appearing in most of the competitive exams, but its indirect application makes this topic very relevant from the Quant section point of view. Simplification or simplify fractions means to simplify a complicated mathematical expression to get a single or direct answer.
To understand it clearly, let us solve the following example.
Illustration: Solve 12 + 8 ÷ 4
Sol: The correct solution is as follows = 12 + 8 ×(1/4) = 12 + 2 = 14
Note: Many students will solve it as follows: 12 + 8  4 = 20 ÷ 4 = 5 which is wrong. We must follow the Bodmas formula. According to BODMAS rule, multiplication should be after division. Given below are the details of the letters and the sequence to be followed while solving simplification or BODMAS based questions.
 BODMAS rule
BBracket (Brackets are solved in order of (), {} and [] respectively.
OOf Þ multiplication, but it is to be done before division.
DDivision
MMultiplication
AAddition
SSubtraction

Time and Work

If A can do a piece of work in n days, then A's 1 day's work = 1/n  If A and B work together for n days, then (A+B)'s 1 days's work = 1/n  If A is twice as good workman as B, then ratio of work done by A and B = 2:1  Basic Formula : If M1 men can do W1 work in D1 days working H1 hours per day and M2 men can do W2 work in D2 days working H2 hours per day (where all men work at the same rate), then  M1 D1 H1 / W1 = M2 D2 H2 / W2  If A can do a piece of work in p days and B can do the same in q days,  A and B together can finish it in pq / (p+q) days. Illustration 1:   Samir can do a job in 30 days. In how many days can he complete 70% of the job? Sol:  Now as per the question he finishes the work in 30 days, or he can do 100% of the work in 30 days. If he has to do only 70% of the work, he will require 70% of the time.  Number of days required = 30 × 70/100 = 21 days. Illustration 2:   Reshma can do 75% job in 45 days. In how many days ca...

Profit and loss

Formulae:- Gain = Selling Price(S.P.) - Cost Price(C.P)  Loss = Cost Price (C.P.) - Selling Price (S.P) Gain % = Gain x 100 / C.P. Loss % = Loss x 100 / C.P  S.P. = [(100 + Gain%)/100] x C.P  S.P. = [(100 - Loss%)/100] x C.P  C.P. = [100/ (100 + Gain%) ] x S.P  C.P. = [100/ (100 - Loss%) ] x S.P  When a person sell two similar items , one at a gain of say x% , and other at a loss of x% then the seller always incure a loss given by - Loss % = ( Common loss & gain % / 10 )2  If a trader professes to sell his goods at cost price , but uses false weight , then Gain% = [ Error / (True value – Error ) ] x 100 % TRUE DISCOUNT  Ex. Suppose a man has to pay Rs. 156 after 4 years and the rate of interest is 14% per annum.  Clearly, Rs. 100 at 14% will amount to R. 156 in 4 years. So, the payment of Rs. now will clear off the debt of Rs. 156 due 4 years hence. We say that: Sum due = Rs. 156 due 4 years  hence: Present Worth (P.W.) = Rs. 100;...

LCM and HCF

Greatest Common Divisor (GCD)/ Highest Common Factor (HCF) The highest common factor of two or more numbers is the greatest common divisor, which divides each of those numbers an exact number of times. The process to find the HCF is Express the numbers given as a product of prime numbers separately i.e. finds factors of numbers Take the product of prime numbers common to both numbers Illustration 1: Find the HCF of 1728 and 14. Sol: The prime factorization of 1728 is 12 × 12× 12= 3 3 x2 6 . The prime factorization of 14 is 2 × 7. The common prime factor is 2. HCF = 2. Illustration 2: Find the HCF of 27, 18 and 36. Sol: Firstly find the prime factors of the numbers such as 27 = 3 × 3 × 3, 18 = 3 × 3 × 2 and 36 = 3 × 3 × 2 × 2, then take the common prime numbers, which are 3 & 3. Now the product of these prime numbers i.e. 3 × 3 = 9 is the HCF of these two numbers. Understanding LCM or Least Common Multiple The least common multiple (LCM) of two or more numbers is the smallest of the...
