Boats and Streams shortcut tricks are very important thing to know for your exams. Time takes a huge part in competitive exams. If you manage your time then you can do well in those exams. Most of us miss this thing. Here in this page we give few examples on Boats and Streams shortcut tricks. We try to provide all types of shortcut tricks on boats and streams here. Visitors are requested to carefully read all shortcut examples. You can understand shortcut tricks on Boats and Streams by these examples.

Before doing anything we recommend you to do a math practice set. Then find out twenty math problems related to this topic and write those on a paper. Using basic math formula do first ten maths of that page. You also need to keep track of Timing. After solving all ten math questions write down total time taken by you to solve those questions. Now read our examples on boats and streams shortcut tricks and practice few questions. After finishing this do remaining questions using Boats and Streams shortcut tricks. Again keep track of the time. This time you will surely see improvement in your timing. But this is not all you want. You need more practice to improve your timing more.

You all know that math portion is very much important in competitive exams. It doesn’t mean that other topics are not so important. But if you need a good score in exam then you have to score good in maths. You can get good score only by practicing more and more. All you need to do is to do math problems correctly within time, and this can be achieved only by using shortcut tricks. But it doesn’t mean that you can’t do math problems without using any shortcut tricks. You may have that potential that you may do maths within time without using any shortcut tricks. But so many other people may not do the same. For those we prepared this boats and streams shortcut tricks. We try our level best to put together all types of shortcut methods here. But we may miss few of them. If you know anything else rather than this please do share with us. Your little help will help so many needy.

**Boats and Streams Example 3:**

This is the basic theory of Boat and Stream which is applied in question to obtain answers here Boat and Stream Methods of example in different form of examples.

In maths exam papers there are two or three question are given from this chapter.This type of problem are given in Quantitative Aptitude which is a very essential paper in banking exam.Under below given some more example for your better practice.

**Example 1:** The speed of a boat in still water is 18 km/hr and the rate of current is 6 km/hr. What distance passes downstream in 14 minutes ?

**Answer :** Speed downstream = (18 + 6)km/hr = 24km/hr.

Distance passes = (24 x 14 / 60)km = 5.6 km.

**Example 2:**

Speed of a boat in still water is 12 km/hr and the speed of the stream is 4 km/hr. A boy row to place which at a distance of 80 km and then he come return to his starting point.

**Answer :**

12 – 4 = 8 (speed of upstream)

12 + 4 = 16 (speed of downstream)

So, total time taken ( 80 / 8 + 80 / 16 )hours = 15 hours.

**Example 3:**

A man can row upstream at 10 km /hr And downstream at 18 km/h.what is the speed of the stream ?

**Answer :**

Speed of stream = 1 / 2(a – b )

1 / 2 ( 18 – 10 ) km/h = 4 km/h .

**Example 4:**

A boat can travel with a speed of 14 km / hr in still water.if the speed of the stream is 4 km/ hr, find the time taken to go 72 km downstream.

**Answer :**

Speed of downstream (14 + 4 ) = 18 km/ hr

Time taken to travel 72 km downstream

= 72 / 18 = 4 hrs

So time taken to go downstream is 4 hrs.

**Example 5:**

If a steam boat goes 8 km upstream in 40 minutes and the speed of stream is 5 km/h, In still water what would be the speed of the boat ?

**Answer :**

Rate of stream = 8 x 60 / 40 = 12 km/h. [ convert minutes to hour we multiplying by 60 ]

the speed of stream is 5 km/h

Let speed in still water be x km / hr.

If stream speed 5 km then speed of upstream would be = ( x – 5 ) km/hr

Then, speed upstream = (x – 5 ) km / hr.

So, x – 5 = 12

x = 12 + 5 = 17 km/hr.

**Example 6:**

Jonny can row a certain distance downstream in 8 hours and upstream the distance in 10 hours , If the stream flows rate at of 4 km / hour then , Find the speed of jonny in still water .

**Answer :**

Speed of jonny in still water be z km /hr

downstream speed = ( u – v)

upstream speed = ( u + v)

Shortcut tricks :

Speed of jonny in still water is =

rate ( upstream speed + downstream speed / upstream speed – downstream speed )

4 ( 10 + 8 ) / 10 – 8 = 36 km / hr .

it is nice

Very usefull

thank u..

very useful

SIR FIRST QUESTION ME 60 KAHA SE AAYA HAI MUJHE SAMJH NHI AAYA

mins ko hour me convert krne k liye d=s*t. 8=s*40/60

Nicely described… thank u …

I think u have to increase no. and variety of questions….

It ll b better if u giv more problems as examples

A man can row 7 km/hr in still water. If the river is running at 3km/hr,it takes 6hrs more in upstream then go to downstream for the same distance how far is the place?pls give me the. Solution

10*X=4*(X+6); Hear X is time taken to reach that place in down stream.

X=4hours;

Total one way distance is total speed(person’s+ stream)*time taken.

I.e 10*4=40km.

thank you

very useful
