Therefore each woman contributed 1\/32th of the item per day.<\/p>\n 4 women working for 4 days = 16\/32th part of the item = 1\/2 part of the item<\/p>\n 12 children therefore make 1\/2 part of the work in 4 days<\/p>\n Therefore 12 children can do 1\/8th part in day<\/p>\n Therefore 1 child can do 1\/96th part of item per day<\/p>\n Therefore 4 children can do 4\/96th part of item per day<\/p>\n Hence 4 children will take 96\/4 = 24 days to finish the work.<\/p>\n <\/p>\n <\/p>\n 14)\u00a0Answer\u00a0(E)<\/strong><\/p>\n Let the total work be W 15)\u00a0Answer\u00a0(D)<\/strong><\/p>\n Rate of doing work by A and B is $\\frac{1}{A} $ and $\\frac{1}{B}$ Highly Rated Free Preparation App for Banking Exams<\/a><\/p>\n
\nLet the work completed by B in one day = $\\frac{1}{B}$
\nLet the work completed by C in one day = $\\frac{1}{C}$
\n$\\frac{1}{A}$ +\u00a0$\\frac{1}{B}$ =\u00a0$\\frac{1}{20}$
\n$\\frac{1}{B}$ +\u00a0$\\frac{1}{C}$ =\u00a0$\\frac{1}{30}$
\n$\\frac{1}{A}$ +\u00a0$\\frac{1}{C}$ =\u00a0$\\frac{1}{40}$
\nSolving the above equations we get $\\frac{1}{A}$\u00a0= $\\frac{1}{24}$
\nA = 24
\nSimilarly B = 120 and C = 60
\n3)\u00a0Answer\u00a0(B)<\/strong><\/p>\n
\nThey work for total 8*5= 40 hours
\nx+y=(576000)\/40
\n1.8x=14400
\nx=8000<\/p>\n
\nNow, b=.5c, a=.5b=.25c
\nc does work in 7 days. It’s speed will be W\/7. A’s speed will be .25W\/7 and B’s speed will be .5W\/7
\nTheir combined speed is 1.75W\/7
\nTime taken by them to complete the work = $\\frac{W}{(1.75W\/7)}$ = $\\frac{7}{1.75}$= 4
\nHence, together they will complete the work in 4 days.
\nTherefore, option C is correct.<\/p>\n
\nSo, the amount of work done by a man in a day is W\/2.
\nAnd the amount of work done by a child in a day is W\/4
\nSo, the amount of work done by 3 men, 4 women and six children in a day is 3W\/2 + 4W + 6W\/4 = 7W.<\/p>\n
\nWork done by 12 men in 1 day = $\\frac{1}{24}$
\nWork done by 1 man in 1 day = $\\frac{1}{24\\times12}$
\nWork done by 16 men in 1 day = $16 \\times(\\frac{1}{24\\times12}) = \\frac{1}{18}$
\nHence, 16 men will take 18 days to finish the work.<\/p>\n
\nRemaining time = 8 days
\nWork done by 36 persons in 1 day = $\\frac{1}{40}$
\nWork done by 1 person in 1 day = $\\frac{1}{36 \\times 40}$
\nLet the number of persons required to finish the remaining work be ‘x’
\n$8 \\times x \\times \\frac{1}{36\\times40} = \\frac{1}{4}$
\n$x = 45$
\nNumber of additional persons = 45 – 36 = 9<\/p>\n
\nHence, 24 children’s work can be completed by 8 women.
\nWork done by 1 woman in 1 day = $\\frac{1}{28\\times 8}$
\nWork done by 28 women and 24 children in 1 day = Work done by (28+8 = 36) women in 1 day
\n= $\\frac{36}{28 \\times 8}$
\n= $\\frac{9}{56}$
\n$\\therefore$ Number of days required by them = $\\frac{56}{9} = 6 \\frac{2}{9}$<\/p>\n
\nSince two men or six women or four boys can finish a work in 99 days
\nSo the amount of work done by one man in a day = $\\frac{W}{198}$
\nAmount of work done by one woman in a day = $\\frac{W}{594}$
\nAmount of work done by one boy in a day = $\\frac{W}{396}$
\nSo total work done by one man, one woman and one boy in a day = $\\frac{W}{198}$ +$\\frac{W}{594}$ + $\\frac{W}{396}$ = $\\frac{11W}{1188}$
\nThus number of days that one man, one woman and one boy together take to finish the same work = $\\frac{W}{ \\frac{11W}{1188}}$
\n= 108 days <\/span><\/span><\/p>\n
\n$\\frac{1}{A} $ = $\\frac{3}{B}$
\nIn 4 days A would have completed $\\frac{4}{A}$ or $\\frac{12}{B}$ amount of work
\nIn 15 days B would have completed $\\frac{15}{B}$ amount of work
\nSince total work done was 75%.
\n$\\frac{12}{B} + \\frac{15}{B} = \\frac{3}{4}$
\n$\\frac{27}{B} = \\frac{3}{4}$
\n$\\frac{1}{B} = \\frac{1}{36}$
\nB alone would take 36 days to complete the work.
\nOption D is the correct answer.<\/p>\n
