**ML Aggarwal CBSE Solutions Class 8 Math 8th Chapter Direct and Inverse Variation Exercise 8.1**

**(2) **(i)

x | 3 | 5 | x_{3} |
x_{4} |
10 |

y | 45 | Y_{2} |
90 | 120 | Y_{5} |

Now, x/y = constant

Taking = 5/y_{2} = 3/45 => y_{2} = 75 (Ans)

x_{5}/90 = 3/45 => x_{3} = 6 (Ans)

x_{4}/120 = 3/45 => x_{4} = 8 (Ans)

10/y_{5} = 3/45 => y_{5} = 150 (Ans)

(ii)

x | 4 | 8 | x_{3} |
20 | 28 |

y | 7 | Y_{2} |
21 | Y_{4} |
Y_{5} |

Now, x/y = Constant

8/y^{2} = 4/7 => y_{2} = 14 (Ans)

x_{3}/21 = 4/7 => x_{3} = 12 (Ans)

20/y_{4} = 4/7 => y_{4} = 35 (Ans)

28/y_{5} = 4/7 => y_{5} = 49 (Ans)
