\nMore men can earn more in a day.
\nIn a day 4 men can earn money= Rs 320
\n1 man can earn =Rs 320\/4 and
\n6 men can earn Rs 320\/4 \u00d7 6 = Rs 480
\nAlso, 2 women can earn Rs 320 and
\n1 woman can earn Rs 320\/2 = Rs 160
\n12 women can earn = Rs 160 \u00d7 12 = Rs 1920
\nTherefore, 6 men and 12 women can earn Rs(480 + 1920) = Rs 2400.<\/p>\n<\/details>\n
\nSolution:<\/strong><\/summary>\n
\nSolution:<\/strong><\/summary>\n
\nAjay saves money in 12 days=Rs 960
\nSaving of Ajay in 1 day=960\/12
\n\u200b=80 Rs
\nSaving of Ajay in 25 days=80 \u00d7 25 =2000 Rs
\nTherefore, Ajay saves Rs 2000 in 25 days.<\/p>\n<\/details>\n
\nSolution:<\/strong><\/summary>\n
\n<\/strong>No.of apples placed in 25 cartoons is 350
\nNo.of apples can be placed in 1 cartoon =350\/25
\n\u200b=14 apples
\nHence, No. of apples can be placed in 16 cartoons =16 \u00d7 14= 224 apples.<\/p>\n<\/details>\n
\nSolution :<\/strong><\/summary>\n
\nBecause more time —–> more earning
\nGiven that,
\nEarning for 2 years is Rs 8000
\nEarning for 1 year is
\n= 8000 \/ 2
\n= Rs4000
\nThen, earning for 5 years is
\n= 5 \u22c5 4000
\n= Rs 20,000
\nSo, the earning for 5 years is Rs 20,000.<\/p>\n<\/details>\n
\nSolution:<\/strong><\/summary>\n
\nBecause
\nmore miles —–> more cost
\nGiven that,
\nCost for one mile = Rs 5.50
\nThe cost of 300 miles is
\n= 5.50 \u22c5 300
\n= Rs 1650
\nHence, the total cost for the trip is Rs 1650.<\/p>\n<\/details>\n
\nSolution:<\/strong><\/summary>\n
\nBecause fewer units —–> less cost
\nCost of 500 gm = Rs 495
\nThe cost of 1 unit is
\n= 495 \/ 500
\n= 0.99
\nThe cost of 280 units is
\n= 0.99 \u22c5 280
\n= Rs 277
\nSo, Janci has to pay Rs 277 for 280 units.<\/p>\n<\/details>\n
\nSolution :<\/strong><\/summary>\n
\nmore gallons of juice —–> amount received will be more
\nGiven that, 2 litres of juice cost Rs 40
\nThe cost of one gallon of juice is= 40 \/ 2
\n= Rs 20
\nThe Cost of 70 litres of juice is
\n= 70 \u22c5 20
\n= Rs 1400
\nHence, Dev will earn Rs1400 by selling 70 litres of juice.<\/p>\n<\/details>\n
\nSolution:<\/strong><\/summary>\n
\nmore number of weeks —-> amount raised will be more
\nGiven that, Sarath raised Rs 2,379 in 20 days
\nAmount raised in one day is
\n= 2379 \/ 3
\n= Rs 793
\nAmount raised in 20 days is= 793 \u22c5 20
\n= Rs 15860
\nHence, the money raised in 20 weeks is Rs15860.<\/p>\n<\/details>\n
\nSolution:<\/summary>\n
\nThe number of words typed in 1min=690\/30=23
\nTherefore, the number of words typed in 10min=10\u00d723=230.
\nHence, Ramya will be able to type 230 words in 10 minutes.<\/p>\n<\/details>\n
\nSolution:<\/summary>\n
\nBecause
\nless number of plastic boxes —–> cost will be less
\nGiven that, 75 plastic boxes cost Rs 3,750
\nThe cost of one plastic box is
\n= 3750 \/ 75
\n= Rs 50
\nThen, the cost of 24 plastic boxes is
\n= 24 \u22c5 50
\n= Rs 1200
\nTherefore, the cost of 24 plastic boxes is Rs 1200.<\/p>\n<\/details>\n
\nSolution:<\/strong><\/summary>\n
\nThe cost for 20 m of cloth is= Rs 900
\nThe cost for 1 m of cloth is =900\/20
\n=45 Rs
\nThus, the cost for 65 m of cloth =65 \u00d7 45= Rs 2925<\/p>\n<\/details>\n
