            12 men can do a work in 30 days. 18 men takes as much days to complete half work as 20 women can do 1/3rd work in that time. Find in how many days 25 women can do the whole work?
            total work 12*30=360
            18m/1/2=20w/1/3
            36m=60w
            6m=10w
            3m=5w
            15m=25w
            360/15=24

            bro:( wait i am doing all again sorry sab wrong he h phone se kiya type lgta h sab auto correct ki wajha se phon me jo the wahi type hogye h

          4. DAS

            question me type thoda mistake he
            it should be equal to ok
            5000*9*4/100=(5000+x)*11*3/100
            now you can find x?

  4. Always smile

    1st
    simple
    4 extra than c
    so a+b=c+d
    11+11+28=9+9+32
    equal
    2nd
    ——-
    total work 12*30=360
    18m/1/2=20w/1/3
    36m=60w
    6m=10w
    3m=5w
    15m=25w
    360/15=24===========
    ====================3rd
    p+2x)*44-p+x)*44=176
    44x=17600
    x=400
    ============4th
    a=200*2+200*6 b=800*6+400*6
    so a=1600 b=7200
    ratio=2:9
    a=2100*2/11 =4200/11
    ======5th
    mp=4800

    =========8th
    In a vessel the ratio of milk and water is 4 : 1. If some quantity of water is added then ratio becomes 16 : 5. Then 21 litres of mixture is taken out and in final mixture milk becomes 64 litres. Find how much water was added to the initial mixture?
    intially=4;1
    later add water so ratio =16;5
    change in only water so make milk equal
    m;w
    16;4———-intially
    16;5–later
    21 with draw
    16x-16/5x-5
    after that 64 litr milk
    16x-16=64
    x=5
    final
    80==milk
    20==water
    after add—intailly 16;5
    16*5=80
    5*4=20

    so 4ltr.

        p+2x)*44-p+x)*44=176
        44x=17600
        x=400
        just using simple formula try once bro@a@aryan_chintu:disqus

    5. BT

      8 ka ans =5 aayega
      initial ratio 16: 4 and after addind water
      16:5 he so if X=5 then
      80: 20 initial
      80:25 after adding water
      means water added is 5 litres

  5. Always smile

    @@disqus_eIwvRwbFgb:disqus @@balakrushnadass:disqus given bro
    if any error then correct me bro:)
    also for doubt also
