Answer:

Rajan = 436.36 rupees and Kamal = 363.63 rupees

Step-by-step explanation:

Total ratio = 11/30

Amount to be shared = 800

Rajan = Individual ratio / Total ratio x the total amount to be shared

1/5 ÷11/30 × 800 = 436.36

Kamal = 1/6 ÷ 11/30 × 800 = 363.63

If 9x+2y^2−3z^2=132 and 9y−2y^2+3z^2=867, then x+y =

8_murik_8 [283]

Answer:

$x + y = \frac{1000}{9}$

Step-by-step explanation:

Step 1: Identify the approach:

With this problem, the general solution is to try manipulate given data and transform data into a new form, in which, the desired value $(x + y)$ is on the left side and all of other components which do not contain $x$ or $y$ are on the right side.

Step 2: Analyze:

$9x + 2y^{2} - 3z^{2} = 132\\9y - 2y^{2} + 3z^{2} = 867$

Realize that in both equations, the $2y^{2}$ and $3z^{2}$ are in form of different signs. Then adding up corresponding sides of both equation can help eliminate these undesired components.
