\nThen, d\/4-d\/5=15min=1\/4 h \u21d2d 1\/20=1\/4\u21d2d=5km<\/p>\n
\nBoat speed while going upstream = v-x = 28
\nBoat speed while going downstream = v+x = 32
\n=> 2v = 60 => v = 30
\nHence, none of these is the correct answer.<\/p>\n
\nNew speed = 1.4*15 = 21 units\/min
\nTime taken by Shweta to complete 300 units of work at a speed of 21units\/min = 300\/21 ~14
\nTime difference = 6 minutes<\/p>\n
\nx+y = (W\/4)
\nNow, x = (W\/12)
\nTherefore, y = W\/6
\nHence, y can complete piece of work in 6 days.<\/p>\n
\nThe number of days it takes 1 man to complete the job is 32*16 = 512 days.
\nHence, the number of days it takes 16 men to complete the job is 512\/16 = 32 days.
\nAs none of the options is 32 days, the correct answer is option (e)<\/p>\n
\nNumber of stoppages = 375\/125-1 = 2
\nTotal time to stoppages = (5 \u00d7 2 ) min = 10 min
\nHence, total time taken = 5 h 10 min<\/p>\n
\nRelative speed = x + 9(5\/18) = x + 2.5
\nSpeed = 210\/6 = 35m\/s
\nx + 2.5\u00a0= 35 => x = 32.5\u00a0m\/s = 32.5 * (18\/5) = 6.5 * 18 = 117 kmph<\/p>\n
\n1 Woman does 1\/(4*4) = 1\/16 amount of work in a day
\n1 Child does 1\/(5*4) = 1\/20 amount of work in a day
\n2 Men , 4 Women and 10 Children will do 2*1\/8+4*1\/16+ 10*1\/20 = 1\/4+1\/4+1\/2 = 1 amount of work in a day
\nHence, they will finish in 1 day.<\/p>\n
\nSo, the number of days it takes 1 man to complete the piece of work is 10*8 = 80 days.
\nHence, the number of days it takes 16 men to do the same piece of work is 80\/16 = 5 days.<\/p>\n
\nNumber of hours required by one child to complete the work = 120
\nSo, 80W = 120C => 1W = 1.5C
\n6 women + 3 children = 9 children + 3 children = 12 children
\nSo, 12 children take 10 days to complete the work.<\/p>\n
