37.	Plz tell what is the meaning of described in this q
Answer» From Figure: Given ABCD is a square WHOSE one diagonal is AC. ΔAQC and ΔBPC are EQUILATERAL triangles on the diagonals AC and SIDE BC We know that Diagonal of square = √2 * length of the side of the square ⇒ Length of diagonal AC =√2 * BC ⇒ Area of (ΔBPC)/Area of (ΔAQC) = BC^2/AQ^2 = BC^2/(√2BC)^2 = BC^2/2BC^2 = 1/2. Therefore, area (ΔBPC) = (1/2) area (ΔAQC). Hope it helps!

Plz tell what is the meaning of described in this q

Answer»

From Figure:

Given ABCD is a square WHOSE one diagonal is AC.

ΔAQC and ΔBPC are EQUILATERAL triangles on the diagonals AC and SIDE BC

We know that Diagonal of square = √2 * length of the side of the square

⇒ Length of diagonal AC =√2 * BC

⇒ Area of (ΔBPC)/Area of (ΔAQC) = BC^2/AQ^2

= BC^2/(√2BC)^2

= BC^2/2BC^2

= 1/2.

Therefore, area (ΔBPC) = (1/2) area (ΔAQC).

Hope it helps!

suhra and sita started a business together. suhra invested 40000 rupees and sita, 30000 rupees. they made a profit of 7000 rupees which they divided in the ratio of their investments. how much did each get?

Answer»

SUHRA get the PROFIT of Rs 4000 and Sita will get the profit of Rs 3000.

Step-by-step EXPLANATION:

For the new business, Suhra invested Rs 40000 and SIta invested Rs 3000. Total amount invested in the business is

= 40000 + 30000

= 70000

The total profit of the business is 7000.

The RATIO of profit of Suhra is

= $\frac{40000}{70000} \times 7000$

= 4000

The ratio of profit of Sita is

= $\frac{30000}{70000} \times 7000$

= 3000
