Question 1.
\nWhat fraction is 270 gram of 3 kilograms?
\nSolution:
\n<\/p>\n
Question 2.
\nSimplify the following:

\nSolution:
\n<\/p>\n
Question 3.
\nA shirt was marked at \u20b9 540. It was sold at \\(\\frac { 3 }{ 4 }\\) of the marked price. What was the sale price?
\nSolution:
\nList price of the shirt = \u20b9 540
\nSelling price = \\(\\frac { 3 }{ 4 }\\) of 540 = \\(\\frac { 3 }{ 4 }\\) \u00d7 540 = \u20b9 405<\/p>\n
Question 4.
\nIn a class of 56 students, \\(\\frac { 1 }{ 4 }\\) are in blue house and \\(\\frac { 3 }{ 14 }\\) are in yellow house. Out of the remaining, \\(\\frac { 1 }{ 3 }\\) are in the greenhouse and the rest are in the red house. Find the number of students in each house.
\nSolution:
\nNumber of total students of a class = 56
\nNumber of students of blue house = \\(\\frac { 1 }{ 4 }\\) of 56 = 14
\nNumber of students of yellow house = \\(\\frac { 3 }{ 14 }\\) of 56 = 12
\nRemaining students = 56 – (14 + 12) = 56 – 26 = 30
\nNumber of students of green house = \\(\\frac { 1 }{ 3 }\\) of 30 = 10
\nand remaining students who are of red house = 30 – 10 = 20<\/p>\n
Question 5.
\nRohit bought a motorcycle for \u20b9 36000. He paid \\(\\frac { 1 }{ 6 }\\) of the price in cash and the rest in 12 equal monthly instalments. Find the amount he had to pay every month.
\nSolution:
\nCost price of motor cycle = \u20b9 36000
\nCash paid = \\(\\frac { 1 }{ 6 }\\) of \u20b9 36000 = \u20b9 6000
\nRemaining amount = \u20b9 36000 – \u20b9 6000 = \u20b9 30000
\nNumber of installments = 12
\nAmount of each installment = \u20b9 30000 \u00f7 12 = \u20b9 2500
\nRohit had to pay \u20b9 2500 every month.<\/p>\n
Question 6.
\nMr Mukerjee gave \\(\\frac { 5 }{ 14 }\\) of his money to his son, \\(\\frac { 2 }{ 3 }\\) of the remainder to his daughter and the rest to his wife. If his wife got \u20b9 36000, what was that total amount?
\nSolution:
\nLet total money = 1

\n(ii) 0.876
\n(iii) 4.3125
\nSolution:
\n<\/p>\n
Question 9.
\nWrite the following fractions as decimals:
\n(i) 1\\(\\frac { 3 }{ 8 }\\)
\n(ii) \\(\\frac { 47 }{ 125 }\\)
\n(iii) 2\\(\\frac { 9 }{ 40 }\\)
\nSolution:
\n
\n<\/p>\n
Question 10.
\nBy how much does the sum of 17.443 and 29.657 exceed the sum of 13.687 and 18.548?
\nSolution:
\nSum of 17.443 and 29.567 = 17.443 + 29.657 = 47.100
\nand sum of 13.687 and 18.548 = 13.687 + 18.548 = 32.235
\nDifference = 47.100 – 32.235 = 14.865
\n<\/p>\n
Question 11.
\nSimplify the following:
\n(i) 4.27 \u00d7 0.036
\n(ii) 0.09 \u00d7 1.04
\n(iii) 1.32 \u00f7 0.8
\n(iv) 0.7038 \u00f7 0.34
\nSolution:
\n(i) 4.27 \u00d7 0.036 = 0.15372
\n
\n(ii) 0.09 \u00d7 1.04 = 0.0936
\n(iii) 1.32 \u00f7 0.8 \u21d2 1.32 \u00f7 0.80
\n
\n(iv) 0.7038 \u00f7 0.34 \u21d2 0.7032 \u00f7 0.3400
\n<\/p>\n
Question 12.
\nIf one kg of rice costs \u20b9 52.70, then find the cost of 12.5 kg rice.
\nSolution:
\nCost of 1 kg of rice = \u20b9 52.70
\nThen cost of 12.5 kg of rice = \u20b9 52.70 \u00d7 12.5 = \u20b9 658.75 = \u20b9 658.75
\n<\/p>\n
Question 13.
\nA piece of cloth is 24.5 m long. How many pieces, each of length 1.75 m, can be cut from it?
\nSolution:
\nLength of a piece of cloth = 24.5 m
\nLength of one piece of cloth cut from it = 1.75 m
\nNumber of piece = 24.5 \u00f7 1.75 = 24.50 \u00f7 1.75 = 14 pieces
\n<\/p>\n
Question 14.
\nThe product of two decimal numbers is 1.599 and one of them \u00a1s 0.65, find the other.
