        There is an empty reservoir whose capacity is 30 litres. There is an inlet pipe which fills at 5 L/min and there is an outlet pipe which empties at 4 L/min. Both the pipes function alternately for 1 minute. Assuming that the inlet pipe is the first one to function, how much time will it take for the reservoir to be filled up to its capacity???

        1. Mera bhi din ayega :)))

          Iska ans 60 min h ???

          1. Sachin Shukla

            51min aa raha…

          2. Mera bhi din ayega :)))

            Yes see how
            Ek inlet ek outlet h kk
            First 5 l fill kar raha h
            Second 4 lt out kar raha h
            To acc to qus alternatively chal rahe h dono matlab firat min inlet chala second min oulet chala
            To 2 min me 1 lt hi to fill hoga kuki 5 bhara 4 khali hua finally 1 hi to bhara
            Ab see isme first jo given hota h na utna kam kar do matlab total 30capacity thi to 5 lt kam karo matlab 25 lt
            Ab 2 min me 1 lt
            To 50 min me 25 lt
            Ab inlet ki bari ayegi
            5 lt fill kar dega next min me
            So 30 lt in 51 min

        Two partners investede Rs. 1250 and Rs. 850 respectively in a business. They distributed 60% of the profit equally and decide to distribute the remaining 40% as the ratio of their capitals. If one partner received Rs. 30 more than the other, find the total profit????

        1. Mera bhi din ayega :)))

          Let 100x profit h so 60x a n b me equally divide hoga to dono ko 30x milega
          Next jo 40x h vo unke capital ke ratio me divide hoga that means
          1250 : 850
          25:17 now 42 =40x
          So 25 =40x*25/42
          And 17=40x*17/42
          Iska diff lo
          40x *8/42=30
          So 4x= 42*3/8
          100x = 42*3*25/8
          =393.75

          1. Mera bhi din ayega :)))

            Vaise yaha ye 60 x ka koi use nahi h sidhe ratio lo and 40x me divide kar lo and phir diff lekar 30 ke equal le lo usko bas ho jayega

          2. ravi

            hum ratio tak kar liya ,,,,next kaisa solve hoga

          3. Mera bhi din ayega :)))

            Upar kiya to h ratio lene ke baad unka part nikalo as 40x total tha phor uska diff lo and usko 30 ke equal kar do

        2. Player

          A:B = 25:17
          40% T (25-17) /42 =30
          T =393.75
