a gift house allowed 20% discount on the marked price of a doll, 13% VAT was levied on it. If the doll was sold as Rs 1808. What was its marked price?
Answers
Answer:
Profit = 20% = 360 Rs
So, Cost Price = 360 / 20 * 100 = 1800 Rs
And Sales Price = 1800 + 360 = 2160 Rs
Discount = 25% of marked price
So Sales Price = (100 - 25) % = 75 % of mark price.
=> 2160 = 75% of marked price.
=> marked price = 2160/75 * 100 = 2880 rs
Hope it helps you.

Answers
The conclusion is that there is evidence to warrant rejection of the claim that the standard deviation of men's pulse rates is equal to 10 beats per minute.
a. Null and alternative hypotheses Null hypothesis (H0): The standard deviation of men’s pulse rates is equal to 10 beats per minute.H0: σ = 10Alternative hypothesis (Ha): The standard deviation of men’s pulse rates is not equal to 10 beats per minute.
Ha: σ ≠ 10b. Calculation of test statistic The test statistic for the standard deviation is calculated as: \[χ^2 = \frac{(n-1)S^2}{σ^2}\]Where n = sample size, S = sample standard deviation, and σ = hypothesized standard deviation. Substituting the values, \[χ^2 = \frac{(36-1)(64)^2}{(10)^2}\] \[χ^2 = 1322.56\]
c. Calculation of P-value We can use the chi-square distribution table to find the P-value. At a significance level of 0.10 and 35 degrees of freedom (36-1), the critical values are 19.337 and 52.018.
Since the test statistic value (χ2) of 1322.56 is greater than 52.018, the P-value is less than 0.10. Therefore, we reject the null hypothesis and conclude that the standard deviation of men’s pulse rates is not equal to 10 beats per minute.
Since it is a two-tailed test, we divide the significance level by 2. The P-value for the test is P = 0.000. Therefore, the P-value is less than the level of significance (0.10).
d. Conclusion Since the P-value is less than the level of significance, we reject the null hypothesis. Hence, there is evidence to support the claim that the standard deviation of men's pulse rates is not equal to 10 beats per minute.
Therefore, the conclusion is that there is evidence to warrant rejection of the claim that the standard deviation of men's pulse rates is equal to 10 beats per minute.

1. A farmer goes to market with 100 dollars to
spend. Cows cost 10 dollars each, pigs cost 3
dollars each, and sheep cost half a dollar each.
The farmer buys from the cattle dealer, the pig
dealer, and the sheep dealer. She spends exactly
100 dollars and buys exactly 100 animals. How
many of each animal does she buy?
Answers
Let us suppose that the farmer buys x cows, y pigs and z sheep. The total cost of cows, pigs, and sheep bought by the farmer is
10x + 3y + 0.5z.
The total number of cows, pigs, and sheep bought by the farmer is
x + y + z.
Given that the farmer spent exactly 100 and bought exactly 100 animals, we can write two equations as follows.
:\($10x + $3y + $0.5z = $100 ---(1)x + y + z = 100 ---(2).\)
Multiplying equation (2) by 10 on both sides, we get
:10x + 10y + 10z = 1000
Subtracting this equation from equation (1), we get
:7y + 9.5z = 500
The LHS of the equation
7y + 9.5z = 500
is an odd number. This means that either y or z has to be odd and the other even. If y is even, then z has to be odd and vice versa. However, both
3y and 0.5z
are integers.
The solutions are:
x =
52,
y = 8,
z = 40 ---(Option A)
or = 48,
y = 16,
z = 36
x = 44,
y = 24,
z = 32x
= 40,
y = 32
z = 28
The farmer buys 52 cows, 8 pigs, and 40 sheep.
Hence,
the answer is 52 cows, 8 pigs, and 40 sheep.

The base and height of a triangle are in the ratio 4: 5. If the area is 640 sq. cm, find the base and height.
Answers
Answer:
base = 32 cm , height = 40 cm
Step-by-step explanation:
ratio of base : height = 4 : 5 = 4x : 5x ( x is a multiplier )
The area (A) of a triangle is calculated as
A = \(\frac{1}{2}\) bh ( b is the base and h the height ) , then
A = \(\frac{1}{2}\) × 4x × 5x = 2x × 5x = 10x²
given A = 640 , then
10x² = 640 ( divide both sides by 10 )
x² = 64 ( take square root of both sides )
x = \(\sqrt{64}\) = 8
Then
base = 4x = 4 × 8 = 32 cm
height = 5x = 5 × 8 = 40 cm

Find the elasticity of demand (E) for the given demand function at the indicated values of p. Is the demand elastic, inelastic, or neither at the indicated values?
q = 404 - 0.2p^2
a. $22
b. $40
Answers
the value of E is less than 1, the demand is inelastic at $40. Hence, the demand is inelastic at both prices.
Given, demand function, q = 404 - 0.2p^2a) When p = $22, the demand q = 404 - 0.2(22)^2 = 169.6Therefore, at p = $22, q = 169.6.b) When p = $40, the demand q = 404 - 0.2(40)^2 = 164Therefore, at p = $40, q = 164
The elasticity of demand is given by the formula, E = (Δq/Δp) × (p/q)Here, Δp = 40 - 22 = 18Δq = 164 - 169.6 = -5.6Also, q = (404 - 0.2p^2)
Putting the values of p = $22, we getq = (404 - 0.2(22)^2) = 169.6
Therefore, the elasticity of demand isE = (Δq/Δp) × (p/q)= ((-5.6)/18) × (22/169.6)= -0.0392Since the value of E is less than 1, the demand is inelastic at $22.c)
Putting the values of p = $40, we getq = (404 - 0.2(40)^2) = 164
Therefore, the elasticity of demand isE = (Δq/Δp) × (p/q)= ((-5.6)/18) × (40/164)= -0.068
Since the value of E is less than 1, the demand is inelastic at $40. Hence, the demand is inelastic at both prices.

b) Edward and Thomas share some money in the ratio 2:3 Thomas receives £243. How much does each Robert receive?
Answers
Answer:
£ 162
Step-by-step explanation:
Ratio:
Ratio of money = 2 : 3
Edward receives two parts of the money and Thomas receives three parts of the money.
Edward's share = 2x
Thomas share = 3x
Thomas receives £243 which is three parts. Find 'x'.
Thomas share = £ 243
3x = 243
Divide both sides by 3,
x = 243 ÷ 3
x = 81
Now, find Edward's share.
Edward's share = 2x
= 2*81
= £ 162
Answer:
£ 162
Step-by-step explanation:
Ratio:
Ratio of money = 2 : 3
Edward receives two parts of the money and Thomas receives three parts of the money.
Edward's share = 2x
Thomas share = 3x
Thomas receives £243 which is three parts. Find 'x'.
Thomas share = £ 243
3x = 243
Divide both sides by 3,
x = 243 ÷ 3
x = 81
Now, find Edward's share.
Edward's share = 2x
= 2*81
= £ 162

Triangle KLM is similar to triangle NOP. Find the measure of side OP. Round your answer to the nearest tenth if necessary. Figures are not drawn to scale
Answers
To find the measure of side OP, we need to use the concept of similarity between triangles.
When two triangles are similar, their corresponding sides are proportional. Let's denote the lengths of corresponding sides as follows:
KL = x
LM = y
NO = a
OP = b
Since triangles KLM and NOP are similar, we can set up a proportion using the corresponding sides:
KL / NO = LM / OP
Substituting the given values, we have:
x / a = y / b
To find the measure of side OP (b), we can cross-multiply and solve for b:
x * b = y * a
b = (y * a) / x
Therefore, the measure of side OP is given by (y * a) / x.
