V tuule 5dl per leBy selling an article for 3600, a man makes a profit of 20%. What is the cost price of the article? Whatwould his gain% be if he sold the article for 4000?​

Answer»

ANSWER:

S.P of an article = rs 3600

Profit % = 20%

So, C.P = SP (100 /100 + profit)

= 3600 ( 100/100 + 20)

= 3600 x 100/120

= 3000

So, C.P = rs 3000

S.P = rs 4000

So, profit = S.P - C.P

= 4000 - 3000

= 1000

So,profit % = profit /C.P x 100

= 1000/3000 x 100

= 33.333 %

Answer»

Given : The store is selling two types of masks currently type A and type B . The cost of one type A mask is Rs. 15 and of one type B mask is Rs. 20. In the month of April, 2020, the store sold 100 masks for total sales of Rs. 1650.

To FIND : How many masks of each type were sold in the month of April?

(a) 40 masks of type A, and 60 masks of type B

(b) 60 masks of type A, and 40 masks of type B

(c) 70 masks of type A, and 30 masks of type B

(d) 30 masks of type A, and 70 masks of type B

Solution:

Let say Type A mask sold  = x

Total Mask sold = 100

Hence Type B mask Sold  = 100 - x

type A mask is Rs. 15

Selling price of Mask A = 15x

type B mask is Rs. 20

Selling price of Mask B = 20(100 - x)

Total Sell =  15x + 20(100 - x)

= 15x + 2000 - 20x

= 2000 - 5x

2000 - 5x = 1650

=> 5x = 350

=> x = 70

Type A = 70

Type B = 100 - 70  = 30

(c) 70 masks of type A, and 30 masks of type B

6)The adjacent sides of a parallelogram measures 34 m, 20 m and the measure ofone of the diagonal is 42 m. Find the area of parallelogram​

Answer»

*ANSWER:

The diagonal of a parallelogram divides it into TWO congruent triangles. Also, the area of the parallelogram is the sum of the areas of the triangles.

We will now use Hero’s formula to calculate the area of TRIANGLE ABC.

Semiperimeter,

\\ s = \frac{1}{2}(34 + 20 + 42) \\ = \frac{1}{2} (96)

Area of ∆ ABC ,

= > \sqrt{s(s - a)(s - b)(s - c)} \\

= > \sqrt{48(48 - 42)(48 - 34)(48 - 20)} \\

= > \sqrt{48 \times 6 \times 14 \times 28} \\

= > \sqrt{112826} \\

= > 336 \: {cm}^{2}

Area of parallelogram = 2 × Area ∆ ABC

=> 2 × 336
