If a/3=b/4=c/7,then a+b+c/c is equal to what?

Posted by ravindra abhale (May 25, 2017 3 p.m.) (Question ID: 5488)

  • Answers:
  • Ans. Given :  {tex}{a\over 3}={b\over 4}={c\over 7}{/tex}

    So, 
    {tex}=> {a\over 3} ={c\over 7}{/tex} 

    {tex}=> {a\over c} ={3\over 7}{/tex} ..... (1)

    Also, 
    {tex}=> {b\over 4}={c\over 7}{/tex}

    => {tex}{b\over c}={4\over 7}{/tex}

    Now, {tex}{a+b+c\over c} = {a\over c}+{b\over c}+{c\over c}{/tex}

    => {tex} {a\over c}+{b\over c}+ 1{/tex} 
    From (1) and (2)

    {tex}=> {3\over 7 }+{4\over 7} + 1 = {3+4+7\over 7} {/tex}

    => {tex}{14\over 7 } = 2{/tex}

Q.Write a digit in the blank space for each of the following numbers so that the number formed is divisible by 11.
a) 92_382
b) 8_9484

Posted by jaweed ali (May 17, 2017 9:55 a.m.) (Question ID: 5342)

  • Answers:
  • 1. (a) Divisibility rule of 3: A number is divisible by 3 if sum of all the digits of the number is divisible by 3.

    Here, _ + 6 + 7 + 2 + 4 = _ + 19

    Therefore, the smallest digit is 2 so that the total will be 2 + 19 = 21, which is divisible by 3. So now, 26724 is divisible by 3.

    Also, the greatest digit is 8 so that the total will be 8 + 19 = 27, which is divisible by 3, so now 86724 is divisible by 3.

        (b) Divisibility rule of 3: A number is divisible by 3 if sum of all the digits of the number is divisible by 3.

    Here 4 + 7 + 6 + 5 + _ + 2 = _ + 24

    Therefore, the smallest digit is 0 so that the total will be 0 + 24 = 24, which is divisible by 3. So now, 476502 is divisible by 3.

    Also, the greatest digit is 9 so that the total will be 9 + 24 = 33, which is divisible by 3, so now 476592 is divisible by 3.

    2. (a) Divisibility rule of 11: A number is divisible by 11 if the difference of the sums of digits of even places and that of odd places is either 0 or divisible by 11.

    Here, Sum of even places = 8 + _ + 9 = 17 + _ and Sum fo odd places = 2 + 3 + 2 = 7

    Therefore, the required digit is 1, so that the difference will be 18 - 7 = 11 and the number 921382 is divisible by 11

        (b) Divisibility rule of 11: A number is divisible by 11 if the difference of the sums of digits of even places and that of odd places is either 0 or divisible by 11.

    Here, Sum of even places = 8 + 9 + 8 = 25 and Sum fo odd places = 4 + 4 + _ = 8 + _

    Therefore, the required digit is 6, so that the difference will be 25 - 14= 11 and the number 869484 is divisible by 11.

How does the grid system on a map help us to locate places

Posted by Sarib Sehran (Apr 05, 2017 4:47 p.m.) (Question ID: 4725)

  • Answers:
  • Many maps include a grid pattern, or a series of crossing lines that create squares or rectangles. The grid helps people locate places on the map. On small-scale maps, the grid is often made up of latitude and longitude lines. Latitude lines run east-west around the globe, parallel to the Equator, an imaginary line that circles the middle of the Earth. Longitude lines run north-south, from pole to pole. Latitude and longitude lines are numbered. The intersection of latitude and longitude lines, called coordinates, identify the exact location of a place.

    On maps showing greater detail, the grid is often given numbers and letters. The boxes made by the grid may be called A, B, C, and so on across the top of the map and 1, 2, 3, and so on across the left side. In the map’s index, a park’s location might be given as B4. The user finds the park by looking in the box where column B and row 4 cross.
