Answer 1

7. {a,b} i.p. {3,2}

$= > \frac{3}{a} = \frac{2}{b} = k = > a = \frac{3}{k} \: b = \frac{2}{k}$

a-b=17

$= > \frac{3}{k} - \frac{2}{k} = 17 = > \frac{1}{k} = 17 = > k = 17 = ></p><p> a = \frac{3}{17} \: b = \frac{2}{17}$

8. {a,b} i.p. {6,5}

=> 6/a=5/b=k

=>a=6/k b=5/k

4a-b=24/k-5/k= 21k

2a+3b=12/k+15/k= 27k

4a-b/2a+3b= 21k/27k = 7/9
