Correct answer is: 4.5 and 1.5 Explanation: Actual price of diamond = $k\times 6^2$ = 36k where k is constant of proportionately. New price of diamond $=k{x}_1^2+k{x}_2^2$ $=36k\times \frac{5}{8}=k(x_1^2+x_2^2)$ $=\frac{45}{2}=x_1^2+x_2^2$ $=22.5=x_1^2+x_2^2$ $={\left(4.5\right)}^2+{\left(1.5\right)}^2=x_1^2+x_2^2$ Nithin ? answered undefined All Comments
