When someone lends money to other He tries to take interest over the money landed. Generally, he takes the simple or compounded interest Terms related: principle: Amount amount one lends Interest: Extra money one asks when he lends money Rate: Rate at which lender charge interest time= Duration for which the lender lends money to someone Simple Interest: Let 's take that one person lends 100 rs to someone at a simple interest rate of 5 yearly.Then he will receive 5 rs as interest at end of 1st year. 10 rs at the end of 2nd year, 15 rs as interest at the end of 3rd year. Let's take someone lends 100rs for 3 years at a simple interest of 5% then He will receive 100+5*3=115 Let 's say a person lends money x at the simple interest rate of d% then He will receive. d rs every 100 rs every year. Simple Interest: (principle*rate*time(year))/100 Total amount = principle+ Simple interest Compound Interest: Let 's take that one person lends 100 rs to someone at...

In general we frame real life problems into some mathematical formula called equations in which we use constant and some variables(unknown) Example: Ram is 12 years old.Ram 's age is 3/5 of Shyam's age what is Shyam's age. Let Shyam's age is x then 3/5 of sham's age is 3*x/5 x*3/5=12 x=60/3=20 so Shyam's age is 20. Linear equations When there is a linear combination of unknown variables is there then eqn is linear Example: 3x+ 2y+ 4z=9 Non Linear Equations: Equations in which non linear combination of the variable is there then eqn is non linear. When any 2 unknown variable multiplication present in the equation then it is the nonlinear equation. Example: 2x+5yz=98 is a nonlinear equation because yz multiplication is there: Quadratic equation in one variable: x^2 + 4*x + 2=0 is non linear because unknown variable x is being multiplied in term x^2 Quadratic equation in many variable: x^2 + y^2 +z^2 + w=0 cubic equati...

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...

Ratio and Proportion In this post, We will learn about ratio and proportion.  Ratio is a way to compare two quantity by using division. This is a relative comparison bw 2 quantities. it says how much x compare to y when we are comparing x and y.  A ratio can be written in three different ways and all are read as "the ratio of x to y" x to y x:y x/y A proportion on the other hand is an equation that says that two ratios are equivalent. For example 1 litter water mixed in 5 litter milk is equivalent to 2 litter water mixed in 10 litter milk. 5/1 = 10/2 A proportion is read as "x is to y as z is to w" x/y = w/z Where y, z ≠ 0 Please write comments if you find anything incorrect, or you want to share more information about the topic discussed above.

Work and Time In this post, we will learn about work and time concept because there is not any standard formula for the problem which fall in work and time category we will understand it with example. Anil can do a job in 20 days. Babu can do the same job in 5 days. In how many days they can complete the job if they work together? 4 5 6 7 Solution: Efficiency of Anil = (100/20) = 5 Efficiency of Babbu = (100/5) = 20 Efficiency together = Efficiency of Anil + Efficiency of Babbu = 25 it means together they can finish 25% of work in one day For so to finish 100% work they will take (100/25) = 4 Day Efficiency = 100/time Anil and Babu can do a job in 8 days. Babu and Charan can do the same job in 12 days. Anil, Babu and Charan can do the job in 6 days. In how many days Anil and Charan can complete the job? 8 7 6 5 Anil and Babu efficiency = (100/8) = 12.5 Babu and Charan efficiency = (100/12) = 8.33 Anil, Babu and Charan efficiency = (1...

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...

Time, Speed And Distance  In this post, We will learn about time, speed and distance. Important Formula Distance = Time x Speed Time = Distance/Speed Speed = Distance/time Important Units Distance: meter (m), kilometre (km) Time: Hour (h), second (s) speed: meter/second (m/s), kilometre/hour  (km/h) Important Conversion 1 km = 1000 meter 1 h = 3600 s 1 km/h = (5/18) m/s 1 m/s = (18/5) km/h Please write comments if you find anything incorrect, or you want to share more information about the topic discussed above.
