In a competitive exam 50 students passed in English. 60 students passed in Mathematics. 40 studentspassed in both the subjects. None of them fail in both the subjects. Find the number of students who passed at least in one of the subjects ?

Answer»

Given:

Students PASSED in English = 50.

Students passed in MATHEMATICS = 60.

Students passed in both subjects = 40.

To Find:

No. of students passed at least in one of subjects = ?

Solution:

Here,

No. of students passed in English = 50 students.

No. of students passed in Mathematics = 60 students.

No. of students passed in both the subjects = 40 students.

★ Total No. of students who passed in English & Mathematics:

= No. of students passed in English + No. of students passed in Mathematics

= 50 + 60

= 110 Students.

★ Students passed at least in one of subject:

= No. of students passed in English & Mathematics - No. of students who passed in both the subjects

= 110 - 40

= 70 Students.

Thus,

The no. of students who passed at least in one of subjects are 70.

Answer» Given: Inayah needs Rs.100, 000 to start an ice-cream business. To find: The opportunity cost that Inayah has to bear in order to start a business Solution: According to the condition of the QUESTION; Inayah needs ₹1,00,000 to start the business in which she invested ₹40,000 from her saving and the REMAINING amount she takes the loan from the bank with the rate of the INTEREST 5%. so, the amount which she needs to repay to the bank to settle down her balance is given by: 100% = 60,000 the total amount after the interest will be 105%, 1% = 600 105% = 105×600 amount = 63,000 so the total cost bear by Inayah will be ₹40000+₹63000 ₹1,03,000 The opportunity cost that Inayah has to bear in order to start a business is ₹1,03,000

Answer»

Given:

Inayah needs Rs.100, 000 to start an ice-cream business.

To find:

The opportunity cost that Inayah has to bear in order to start a business

Solution:

According to the condition of the QUESTION;

Inayah needs ₹1,00,000 to start the business in which she invested ₹40,000 from her saving and the REMAINING amount she takes the loan from the bank with the rate of the INTEREST 5%.

so, the amount which she needs to repay to the bank to settle down her balance is given by:

100% = 60,000

the total amount after the interest will be 105%,

1% = 600

105% = 105×600

amount = 63,000

so the total cost bear by Inayah will be

₹40000+₹63000

₹1,03,000

The opportunity cost that Inayah has to bear in order to start a business is ₹1,03,000

19.	The marked price of a shirt is 1000, A shopkeeper offers 10% discount and again offers 20% discount on the new price.how much you will have to pay finally?
Answer» Given: The marked price of a shirt is 1000. A shopkeeper offers a 10% discount and again offers a 20% discount on the NEW price. To find: How much you will have to pay finally? Solution: We know that if 2 successive discounts on an article are a% and b% respectively, then the single EQUIVALENT discount on it is given as: $\boxed{\bold{a + b - \frac{a \times b}{100} }}$ The shopkeeper offers a discount of 10% and then again a discount of 20% on the purchase of the shirt ∴ The total discount offered by the shopkeeper is, = $10 + 20 - \frac{10 \times 20}{100}$ = $10 + 20 - 2$ = $30 - 2$ = $28\%$ The marked price of the shirt = Rs. 1000 Therefore, The sales price of the shirt will be, = Marked Price - $(\frac{Discount}{100} \times Mraked \:Price)$ = $1000 - (\frac{28}{100} \times 1000)$ = $1000 - 280$ = $\bold{720}$ Thus, I will finally have to pay Rs. 720 for the shirt. --------------------------------------------------------------------------------------- Also View: What was the original price of an item if a discount of 20 per cent reduced the price to Rs.100? brainly.in/question/13567073 If a “Buy 3, Get 1” sales promotion offer is CHANGED to “Buy 2, Get 1”, what is the additional percentage of discount given? brainly.in/question/23305367 By selling an article at 80% of it's marked price, there is a loss of 12%.

The marked price of a shirt is 1000, A shopkeeper offers 10% discount and again offers 20% discount on the new price.how much you will have to pay finally?

Answer»

Given:

The marked price of a shirt is 1000.

A shopkeeper offers a 10% discount and again offers a 20% discount on the NEW price.

To find:

How much you will have to pay finally?

Solution:

We know that if 2 successive discounts on an article are a% and b% respectively, then the single EQUIVALENT discount on it is given as:

$\boxed{\bold{a + b - \frac{a \times b}{100} }}$

The shopkeeper offers a discount of 10% and then again a discount of 20% on the purchase of the shirt

∴ The total discount offered by the shopkeeper is,

= $10 + 20 - \frac{10 \times 20}{100}$

= $10 + 20 - 2$

= $30 - 2$

= $28\%$

The marked price of the shirt = Rs. 1000

Therefore,

The sales price of the shirt will be,

= Marked Price - $(\frac{Discount}{100} \times Mraked \:Price)$

= $1000 - (\frac{28}{100} \times 1000)$

= $1000 - 280$

= $\bold{720}$

Thus, I will finally have to pay Rs. 720 for the shirt.

Prove that 5+√3 is irrational ,given √3is irrational

Answer»

Answer:

make me as brainliest and thank me and rate me

Step-by-step EXPLANATION:

LET us assume to the contrary that 5-root3 is rational

=>5-root3=a/b (where a and b are CO primes and b not equal to zero)

=>root3=5b-a/b

Here a and b are integers, so 5-a/b is rational , hence root3 is also rational.

But this contradicts our fact that ROOT 3 is irrational.

This contradiction has arisen bcoz of our incorrect assumption that 5-root3 is rational.

hence 5-root3 is irrational

Answer» Step-by-step EXPLANATION: Given:- Principal = Rs.2000 Amount = Rs.2662 TIME = 1 ½ years Interest compounded HALF-yearly. To Find:- The RATE of interest. Solution:- Time = 1 ½ years = 3 half years The formula for finding Amount is:- $\leadsto \sf Amount = P \bigg(1 + \dfrac{r}{100}\bigg)^n$ Here:- • A = Amount = Rs.2662 • P = Principal = Rs.2000 • r = rate = ? • n = time = 3 half years Substituting the values:- $\implies \sf2662= 2000 \times \bigg(1 + \dfrac{r}{100}\bigg)^3$ $\implies \sf \dfrac{2662}{2000} = \bigg(1 + \dfrac{r}{100}\bigg)^3$ $\implies \sf 1.331 = \bigg(1 + \dfrac{r}{100}\bigg)^3$ $\implies \sf {(1.1)}^{3} = \bigg(1 + \dfrac{r}{100}\bigg)^3$ $\implies \sf 1.1= 1 + \dfrac{r}{100}$ $\implies \sf \dfrac{r}{100} = 1.1 - 1$ $\implies \sf \dfrac{r}{100} = 0.1$ $\implies \sf r = 0.1 \times 100$ $\implies \sf r = 10$ For half- yearly, Rate = 10% Rate% per annum = 20% $\large \underline{ \boxed{\sf \therefore \: \textsf{ \textbf{Rate \: of \: Interest = 20\%}}}}$

39.

Find the rate percent per annum if rs 2000 amount to rs 2662 in 1½ years interest being compounded half yearly

Answer»

Step-by-step EXPLANATION:

Given:-

Principal = Rs.2000

Amount = Rs.2662

TIME = 1 ½ years

Interest compounded HALF-yearly.

To Find:-

The RATE of interest.

Solution:-

Time = 1 ½ years = 3 half years

The formula for finding Amount is:-

$\leadsto \sf Amount = P \bigg(1 + \dfrac{r}{100}\bigg)^n$

Here:-

• A = Amount = Rs.2662

• P = Principal = Rs.2000

• r = rate = ?

• n = time = 3 half years

Substituting the values:-

$\implies \sf2662= 2000 \times \bigg(1 + \dfrac{r}{100}\bigg)^3$

$\implies \sf \dfrac{2662}{2000} = \bigg(1 + \dfrac{r}{100}\bigg)^3$

$\implies \sf 1.331 = \bigg(1 + \dfrac{r}{100}\bigg)^3$

$\implies \sf {(1.1)}^{3} = \bigg(1 + \dfrac{r}{100}\bigg)^3$

$\implies \sf 1.1= 1 + \dfrac{r}{100}$

$\implies \sf \dfrac{r}{100} = 1.1 - 1$

$\implies \sf \dfrac{r}{100} = 0.1$

$\implies \sf r = 0.1 \times 100$

$\implies \sf r = 10$

For half- yearly, Rate = 10%

Rate% per annum = 20%

$\large \underline{ \boxed{\sf \therefore \: \textsf{ \textbf{Rate \: of \: Interest = 20\%}}}}$
