Basic of Calender Learning for Grade 2 | Mathematics

The concept of the calender originated from solar year. The earth completes its orbit about the sun in 365 days 5 hr 48 min 46 sec.This is called solar year. Total Number of months in a year = 12 Total Number of days in a year = 365 Total Number of days in a leap year = 366 If any year is divisible by 4 then the year is called a leap year. For example: 2008, 2012, 2016 etc are the leap years. To determine the number of days of any mount we count on our hand's back as shown in second diagram. Total Number of months of 31 days in a year = 7 Total Number of months of 30 days in a year = 4 Total Number of months of 28 days or of 29 days in a year = 1

Unitary Method in Simple words - Learn Maths Basics

Unitary means "of one" . Mathematically it means "1". To know this in an easy way, I am writing few examples. Question 1: If the cost of one pen is Rs 2 . Find the cost of 25 Pens Question 2: If the cost of 50 pencils is Rs 500. oo . Find the cost of One pencil . I am modifying the above Sum a little bit . Question 3: If the cost of 50 pencils is Rs 500.00 . Find the cost of 12 pencil . Now the basic rule is : For question 1. If we know the cost or other parameter of one thing , then to know the cost of many thing we will do multiplication . Here we know the cost of 1 pen . Therefore the cost of 25 pen will be MORE than the cost of 1 one pen. Here we realize for more value . Therefore we will multiply. Also watch the image cost of ONE to cost of MANY means MULTIPLY. Solution 1: &#x2235 the cost of 1 pen is Rs. 2 ∴ the cost of 25 pens is 2x25 [ we realize for more value. ]               = Rs. 50 For question 2. And if we

Speed Distance Time Math Class 8 Part 1

The most important thing about this chapter is that the sums are very easy and can be solved by most of the students if the formula is known to him. Also it is more important to keep in memory the formula of speed, distance and time. The third most important point to note is the unit of speed given in the sum and units of distance and time. It is here the student's minds are confused. Be clear about km/hr and m/sec and mile/hr. For converting km/hr to m/s multiply by 5/18 as it can be noticed in the above image. And for converting m/s to km/hr multiply by 18/5 Sometime it is written as : 60 kmph = it means 60 km/hr 60 mph = it means 60 m/hr or 60 mile/hr

A train left New Delhi for Chennai at 10 AM | with a speed of 70 km/hr | Another Train also left New Delhi for Chennai | at 11 AM with a speed of 90 km / hr | At what time 2nd Train will overtake the first train |

The question is again rewritten here: Question : A train left  New Delhi for Chennai at 10 AM  with a speed of 70 km/hr . Another Train also left New Delhi for Chennai  at 11 AM with a speed of 90 km / hr   .  At what time 2nd Train will overtake the first train . Solution: The main point of understanding this sum is that the distance where the 2nd train will overtake the first one will be same . Also the time taken by the first trains will be 1 hr more than the 2nd trains. Also remember that the slower train will take more time than the faster train. Therefor we can create in one line . 90t = 70 (t+1) <br /> where t = time taken by the 2nd trains . * See solution in the image also. the distances are equal . 90t-70t=20t :. t=70/20 :. t=3.5 Hrs Therefor 2nd trains will overtake first one at (11 + 3.5) Hrs . I. e. At 14:30 hrs or 2:30 pm .

A sum of Money becomes double in 3 years | At a compound rate of interest | What is rate of Interest | In how many times it will become 8 times

Sometimes this type of sum are given by the teaches in which logarithm cannot be used at grade or class 8 level. Teacher want to puzzle students so that more students join to their private coaching. You need not to worry . We are here to help the needy students. Let first reed the Sum . This sum will be shown by two method. first one is preferable for students of class 8 to class 10 Question:- A sum of money becomes double in 3 years at a compound rate of interest. Howmany years It will be its 8 times at the same rate. Find the compound rate of interest and the time in which it becomes its 8 times. 1st method solution: Let 'x' becomes 2x in 3 years. We know that : A=P(1+r/100) t A=Amount P= Principal r=compound rate of interest t=time &#x2235 2x=x (1+r/100) 3 ∴ 2 = (1+ r/100) 3 Now 8x=x(1+r/100) t 8 = (1+r/100) t Or 2 3 = (1+ r/100) t or [(1+ r/100) 3 ] 3 =(1+r/100) t or (1+ r/100) 3x3 =(1+r/100) t (1+ r/100) 9 =(1+r/100) t Now the base (1+
