If 2500 is to be divided among Ravi, Raju and Roy, so that Ravi gets two parts, Raju has

fenix001 [56]

Answer:

The money each will get are 500 to Ravi , 750 to Raju and 1250 to Ravi. And there percentages are Ravi's 20%, Raju's 30% and Roy's 50%.

Step-by-step explanation:

Given:

2500 is to be divided among Ravi, Raju and Roy, so that Ravi gets two parts, Raju has three parts and Roy five parts.

Now, to find the money each will get and the percentages of it.

Let the price of one part be $x.$

The price of two parts be $2x.$

The price of three parts be $3x.$

And the price of five parts be $5x.$

According to question:

$2x+3x+5x=2500.$

$10x=2500$

Dividing both sides by 10 we get:

$x=250.$

Ravi gets two parts = $2x=2\times 250=500.$

Raju gets three parts = $3x=3\times 250=750.$

Roy gets five parts = $5x=5\times 250=1250.$

Now, the percentage of the money they get:

Percentage of Ravi's share:

$\frac{500}{2500} \times 100\\=\frac{50000}{2500} \\=20\%.$

Percentage of Raju's share:

$\frac{750}{2500} \times 100\\\\=30\%.$

Percentage of Roy's share:

$\frac{1250}{2500} \times 100\\\\=50\%.$

Therefore, the money each will get are 500 to Ravi , 750 to Raju and 1250 to Ravi. And there percentages are Ravi's 20%, Raju's 30% and Roy's 50%.

Graph y <img src="https://tex.z-dn.net/?f=y%5Cleqslant%201%20-%203x" id="TexFormula1" title="y\leqslant 1 - 3x" alt="y\leqsl

Sav [38]

Answer:

option on first row on the right

Step-by-step explanation:

Since the inequality contains an equal sign, the boundary line must be included in the graph (it should appear as solid)then you need the points y that are less (below) those on the boundary line. So you should highlight the half plane below the boundary line.
