NCERT Solutions for Class 8 Maths Chapter 8 Comparing Quantities Exercise 8.1<\/h2>\n

Question 1.
\nFind the ratio of the following:
\n(a) Speed of a cycle 15km per hour to the speed of scooter 30 km per hour.
\n(b) 5 m to 10 km
\n(c) 50 paise to \u20b9 5
\nSolution:
\n(a) Speed of the cycle = 15 km per hour.
\nSpeed of the scooter = 30 km per hour.
\n\u2234 Ratio = Speed of the cycle : Speed of the scooter
\n= 15 : 30
\n= 1 : 2 (Divided by 15)<\/p>\n

(b) 10 km = 10 \u00d7 1000 m = 10000 m
\nRatio = 5 m : 10 km
\n= 5 : 10000
\n= 1 : 2000<\/p>\n

(c) \u20b9 5 = 5 \u00d7 100 paise = 500 paise
\nRatio = 50 paise : \u20b9 5
\n= 50 : 500
\n= 1 : 10<\/p>\n

\"NCERT<\/p>\n

Question 2.
\nConvert the following ratios to percentages.
\n(a) 3 : 4
\n(b) 2 : 3
\nSolution:
\n(a) 3 : 4 = \\(\\frac{3}{4}\\)
\n= \\(\\frac{3}{4}\\) \u00d7 100%
\n= 75%<\/p>\n

(b) 2 : 3 = \\(\\frac{2}{3}\\)
\n= \\(\\frac{2}{3}\\) \u00d7 100
\n= \\(\\frac{200}{3}\\)
\n= 66\\(\\frac{2}{3}\\) %<\/p>\n

Question 3.
\n72% of 25 students are good at mathematics. How many are not good in mathematics.
\nSolution:
\nTotal number of students = 25
\nNumber of students good in mathematics = 72% of 25
\n= \\(\\frac{72}{100}\\) \u00d7 25
\n= 18
\nNumber of students who are not good in mathematics = 25 – 18 = 7
\nPercentage of students not good in mathematics = \\(\\frac{7}{25}\\) \u00d7 100
\n= 7 \u00d7 4
\n= 28%
\nor = \\(\\frac{28}{100}\\) \u00d7 25 = 7 students are not good in Mathematics.<\/p>\n

Question 4.
\nA football team won 10 matches out of the total number of matches they played. If their win percentage was 40, then how many matches did they play in all?
\nSolution:
\nNumber of matches won by the team = 10
\nLet the total number of matches be ‘x’
\nThe team won 40% the total number matches.
\n\u2234 \\(\\frac{40}{100}\\) \u00d7 x = 10
\nx = \\(\\frac{10 \\times 100}{40}\\) = 25
\n\u2234 Total number of matches played = 25.<\/p>\n

Question 5.
\nIf Chameli had \u20b9 600 left after spending 75% of her money, how much did she have in the beginning?
\nSolution:
\nAmount left with Chameli = (100 – 75)% = 25%
\nLet the total amount with Chameli be \u20b9 ‘x’
\n\u2234 25% of total money = \u20b9 600
\n\\(\\frac{25}{100}\\) \u00d7 x = 600
\nx = \\(\\frac{600 \\times 100}{25}\\) = \u20b9 2400
\nAmount in the beginning = \u20b9 2400<\/p>\n

Question 6.
\nIf 60% of people in a city like a cricket 30% like football and the remaining like other games, then what percent of the people like other games? If the total number of people is 50 lakh, find the exact number who like each type of game.
\nSolution:
\nPeople who like cricket = 60%
\nPeople who like football = 30%
\nPeople who like other games = 100 – (60 + 30)
\n= 100 – 90
\n= 10%
\nTotal number of people = 50,00,000
\nNo. of people who like cricket = \\(\\frac{60}{100}\\) \u00d7 50,00,000 = 30,00,000
\nNo. of people who like football = \\(\\frac{30}{100}\\) \u00d7 50,00,000 = 15,00,000
\nNo. of people who like other games = \\(\\frac{10}{100}\\) \u00d7 50,00,000 = 5,00,000<\/p>\n","protected":false},"excerpt":{"rendered":"
