Short Notes on Time and Distance

TIPS AND FORMULAS ON TIME AND DISTANCE: 1. Speed =   Distance/Time 2. Time =   Distance /Speed 3. Distance =  Speed x Time 4 . km/hr to m/s conversion: 1 kmph =   5/18 m/s 5.  m/s to km/hr conversion:   1 m/s =   18/5 m/s 6.  If the ratio of speeds of train A and B is a : b, then the ratio of time taken by them to cover the same distance =  b : a. 7.  If a man covers a certain distance at x km/hr and an equal distance at y km/hr. Then,the average speed during the whole journey is 2xy/(x + y) km/h 8 . The time taken by a train in passing a pole or standing man is the same as the time taken by the train to cover a distance equal to its own length. 9.  The time taken by a train of length 'L' metres in passing a stationary object of length 'B' metres is equal to the time taken by the train to cover a distance equal to  (L + B) m. 10.  If two trains are moving in the same directions at u m/s and v m...

All About Boats Streams

QUICK STUDY NOTES ON BOATS AND STREAMS : 1. Still Water:   If the water is not moving then it is called still water. 2. Stream:  Moving water of the river is called stream. 3. Downstream:  The direction along the stream is called downstream. 4. Upstream:  The direction opposite the stream is called upstream. 5. If the speed of a boat in still water is 'u' km/hr and the speed of the stream is 'v' km/hr, then Speed of boat downstream  = (u + v) km/hr  Speed of boat upstream  = (u - v) km/hr  6.If the speed downstream is 'a' km/hr and the speed upstream is 'b' km/hr, then Speed of boat in still water  =  1/2(a + b) km/hr Speed of stream  = 1/2(a - b) km/hr  Shortcut Formula : Rule - 1:  A man can row certain distance downstream in t1 hours and returns the same distance upstream in t2 hours. If the speed of stream is y km/h, then the speed of man in still water is given by = y{(t2 + t1)/(t2 - t1)} k...

10 Fast Maths Tricks and Shortcuts

10 Fast Maths Tricks and Shortcuts Today I am going to summarise all the maths tricks that will speed up your calculation speed. I used them in CAT and IBPS exam. I am sure that these tricks will help you increase your score. I have written many articles in detail on these topics. Click on respective links to get details. List of Cool Maths Tricks Squaring In this simple trick, we need to modify the equation and make the units digit zero. After all, it is easy to multiply when units digit is zero. For example - Find square of 43 = (43+3) × (43-3) + (3×3) =(46×40) + 9 = (460×4) + 9 = 1840 + 9 = 1849 Finding Square of Any No. From 1 to 100   Pick Any No. Just like this: Multiplication Vedic maths gave us the easiest method to do complex multiplications quickly. This method can be quickly explained with an example. Multiply 62 with 32 Step 1 Step 2 Step 3 Multiplication with 5 Simply multiply the number by 10 a...
