NCERT Solutions for Class 6 Maths Chapter 12 Ratio and Proportion Exercise 12.3<\/h2>\n

Question 1.
\nIf the cost of 7 m of cloth is \u20b9 294, find the cost of 5 m of cloth.
\nAnswer:
\nCost of 7 m of cloth = \u20b9 294
\n\u2234 Cost of 1 m of cloth = \\(\\frac{294}{7}\\) = \u20b9 42
\n\u2234 Cost of 5 m of cloth = 42 \u00d7 5 = \u20b9 210
\nThus, the cost of 5 m of cloth is \u20b9 210.<\/p>\n

Question 2.
\nEkta earns \u20b9 1500 in 10 days. How much will she earn in 30 days?
\nAnswer:
\nEarning of 10 days = \u20b9 1500
\n\u2234 Earning of 1 day = \\(\\frac{1500}{10}\\) = \u20b9 150
\n\u2234 Earning of 30 days = 150 \u00d7 30 = \u20b9 4500
\nThus, the earning of 30 days is \u20b9 9000.<\/p>\n

\"NCERT<\/p>\n

Question 3.
\nIf it has rained 276 mm in the last 3 days, how many cm of rain will fall in one full week (7 days)? Assume that the rain continues to fall at the same rate.
\nAnswer:
\nRain in 3 days = 276 mm
\nRain in 1 day = \\(\\frac{276}{3}\\) = 92 mm
\n\u2234 Rain in 7 days = 92 \u00d7 7 = 644 mm
\nThus, the rain in 7 days is 644 mm.<\/p>\n

Question 4.
\nCost of 5 kg of wheat is \u20b9 30.50.
\n(a) What will be the cost of 8 kg of wheat?
\n(b) What quantity of wheat can be purchased in \u20b9 183?
\nAnswer:
\n(a) Cost of 5 kg of wheat = \u20b9 30.50
\n\u2234 Cost of 1 kg of wheat = \\(\\frac{30.50}{5}=\\frac{3050}{500}\\) = \u20b9 6.10
\n\u2234 Cost of 8 kg of wheat = 6.10 \u00d7 8 = \u20b9 48.80<\/p>\n

(b) From \u20b9 30.50, quantity of wheat can be purchased = 5 kg
\n\u2234 From \u20b9 1, quantity of wheat can be purchased = \\(\\frac{5}{30.50}\\)
\nFrom \u20b9 61, quantity of wheat can be purchased = \\(\\frac{5}{30.50}\\) \u00d7 61
\n= \\(\\frac{5}{3050}\\) \u00d7 6100 = 10 kg<\/p>\n

Question 5.
\nThe temperature dropped 15 degree Celsius in the last 30 days. If the rate of temperature drop remains the same, how many degrees will the temperature drop in the next ten days?
\nAnswer:
\nDegree of temperature dropped in last 30 days = 15 degrees
\n\u2234 Degree of temperature dropped in last 30 days = \\(\\frac{15}{30}=\\frac{1}{2}\\) degree
\n\u2234 Degree of temperature dropped in last 10 days
\n= \\(\\frac{1}{2}\\) \u00d7 10 = 5 degree
\nThus, 5 degree Celsius temperature dropped in 10 days.<\/p>\n

Question 6.
\nShaina pays \u20b9 7500 as rent for 3 months. How much does she has to pay for a whole year, if the rent per month remains same?
\nAnswer:
\nRent paid for 3 months = \u20b9 7500
\n\u2234 Rent paid for 1 months = \\(\\frac{7500}{3}\\) = \u20b9 2500
\n\u2234 Rent paid for 12 months = 2500 \u00d7 12 = \u20b9 30,000
\nThus, the total rent of one year is \u20b9 30,000.<\/p>\n

Question 7.
\nCost of 4 dozens bananas is \u20b9 60. How many bananas can be purchased for \u20b9 12.50?
\nAnswer:
\nCost of 4 dozen bananas = \u20b9 60
\nCost of 48 bananas = \u20b9 60
\n[4 dozen = 4 \u00d7 12 = 48]
\n\u2234 From \u20b9 60, number of bananas can be purchased = 48
\n\u2234 From \u20b9 1, number of bananas can be purchased = \\(\\frac{48}{60}=\\frac{4}{5}\\)
\n= \\(\\frac{4}{5}\\) \u00d7 12.50 = \\(\\frac{4}{5} \\times \\frac{1250}{100}=\\frac{250}{25}\\)
\n= 10 bananas
\n\u2234 From \u20b9 12.50, number of bananas can be purchased
\nThus, 10 bananas can be purchased for \u20b9 12.50.<\/p>\n

Question 8.
\nThe weight of 72 books is 9 kg what is the weight of 40 such books?
\nAnswer:

\n\u2234 For covering 1650 km, a truck will be required diesel
\n= \\(\\frac{2}{11}\\) \u00d7 1650 = 300 litres
\nThus, 300 litres diesel required by the truck to cover a distance of 1650 km.<\/p>\n

Question 10.
\nRaju purchases 10 pens for \u20b9 150 and Manish buys 7 pens for \u20b9 84. Can you say who got the pen cheaper?

\nRaju purchase 10 pens for = \u20b9 150
\n\u2234 Raju purchases 1 pen for = \\(\\frac{150}{10}\\) = \u20b9 15
\nManish purchases 7 pens for = \u20b9 84
\n\u2234 Manish purchases 1 pen for = \\(\\frac{84}{7}\\) = \u20b9 12
