NCERT Intext Question Page No. 204<\/span><\/p>\n

Question 1.
\nObserve the following tables and find if x and y are directly proportional.
\n\"NCERT
\nAnswer:
\n\"NCERT
\ni. e. each ratio is the same
\n.’. x and y are directly proportional<\/p>\n

\"NCERT
\ni. e. all the ratios are not the same x
\nand y are not directly proportional.<\/p>\n

\"NCERT<\/p>\n

\"NCERT
\ni.e. all the ratios are not the same
\nx and y are not directly proportional.<\/p>\n

Question 2.
\nPrincipal = \u20b9 1000, Rate = 8% per annum. Fill in the following table and find which type of interest (simple or compound) change is in direct proportion with time period.
\n\"NCERT
\nAnswer:
\nCase of Simple Interest
\n[P = \u20b9 1000, r = 8% p.a.]
\n\"NCERT
\nIn each case the ratio is the same.
\nThe simple interest changes in direct proportion with time period.
\nCase of Compound Interest [P = \u20b9 1000, r = 8% p.a.]
\n\"NCERT
\n\\(\\frac{\\mathrm{CI}}{\\mathrm{T}}\\) is not the same in each case.
\n\u2234 The compound interest does not change in direct proportion with time period.<\/p>\n

Question 1.
\nObserve the following tables and find which pair of variables (here x and y) are in the inverse proportion.
\n\"NCERT
\nAnswer:
\n(i) x1<\/sub>y1<\/sub> = 50 x 5 = 250
\nx2<\/sub>y2<\/sub> = 40 x 6 = 240
\nx1<\/sub>y1<\/sub> \u2260 x2<\/sub>y2<\/sub>
\nHence, x and y are not in inverse proportion.<\/p>\n

(ii) x1<\/sub>y1<\/sub> = 100 x 60 = 6000
\nx2<\/sub>y2<\/sub> = 200 x 30 = 6000
\nx3<\/sub>y3<\/sub> = 300 x 20 = 6000
\nx4<\/sub>y4<\/sub> = 400 x 15 = 6000<\/p>\n

x1<\/sub>y1<\/sub> = x2<\/sub>y2<\/sub> = x3<\/sub>y3<\/sub> = x4<\/sub>y4<\/sub>
\nHence x and y are in inverse proportion.
\n(iii) x1<\/sub>y1<\/sub> = 90 x 10 = 900
\nx2<\/sub>y2<\/sub> = 60 x 15 = 900
\nx3<\/sub>y3<\/sub> = 45 x 20 = 900
\nx4<\/sub>y4<\/sub> = 30 x 25 = 750
\nx1<\/sub>y1<\/sub> = x2<\/sub>y2<\/sub> = x3<\/sub>y3<\/sub> \u2260 x4<\/sub>y4<\/sub>
\n.’. x and y are not in inverse proportion.
\nNote: (1) When two quantities x and y are in direct proportion (or vary directly), they are also written is x \u221d y.
\n(2) When two quantities x and y are in inverse proportion (or very inversely), they are also written as x \u221d \\(\\frac{1}{y}\\).<\/p>\n","protected":false},"excerpt":{"rendered":"
