Mr Gupta borrowed ₹ 40,000 from a bank. at the end of 5years Mr Gupta had to pay to the bank ₹ 64,000 when was the rate of interest​

Answer»

u>Given :-

PRINCIPLE :- ₹40000

Total Amount :- ₹64000

Time :- 5 years

\:

To Find :-

The rate of interest applied to the loan.

\:

How to do :-

Here, we are given with the principle amount, the total amount paid at end of the time period and the time took to return the money back. We are asked to find the rate of interest that was applied to this loan. So, first we should find the simple interest by SUBTRACTING the total amount and the principle amount. The obtained answer will be the simple interest of this sum. Later, we can find the rate of interest by using the given formula below. So, let's solve!!

\:

Solution :-

Simple Interest :-

{\tt \leadsto \underline{\boxed{\tt Total \: Amount - Principle}}}

Substitute the given values.

{\tt \leadsto 64000 - 40000}

Subtract the values to get the value of simple interest.

{\tt \leadsto \underline{24000}}

\:

Now, let's find the rate of interest by using this formula.

Rate of interest :-

{\tt \leadsto \underline{\boxed{\tt \dfrac{SI \times 100}{P \times T}}}}

Substitute the given values.

{\tt \leadsto \dfrac{24000 \times 100}{40000 \times 5}}

Cancel the zeros in NUMERATOR and denominator.

{\tt \leadsto \dfrac{240 \cancel{00} \times 100}{400\cancel{00} \times 5} = \dfrac{240 \times 100}{400 \times 5}}

Again cancel the zeros in numerator and denominator.

{\tt \leadsto \dfrac{240 \times 1 \cancel{00}}{4 \cancel{00} \times 5} = \dfrac{240 \times 1}{4 \times 5}}

Multiply the numbers in numerator and denominator.

{\tt \leadsto \dfrac{240}{20}}

Write the obtained fraction in LOWEST form by cancellation METHOD.

{\tt \leadsto \cancel \dfrac{240}{20} = \pink{\underline{\boxed{\tt 12 \bf\%}}}}

\Huge\therefore The rate of interest of the sum is 12%.

Find the amount and compound interest on ₹2500 for 2 years compounded annually, the rate of interest being 6% during the first year and 8% during the second year.

Answer»

ution!!

The CONCEPT of compound interest has to be used here. The principal, rate of interest and time is GIVEN. We have to FIND the compound interest.

For 1st year

Principal (P) = Rs 2500

Time (T) = 1 year

Rate of interest (R) = 6%

Interest = (P × R × T)/100

Interest = (2500 × 6 × 1)/100

Interest = Rs 150

Amount = Principal + Interest

Amount = Rs 2500 + Rs 150

Amount = Rs 2650

The amount in the 1st year is the principal of the 2ND year.

For 2nd year

Principal (P) = Rs 2650

Time (T) = 1 year

Rate of interest (R) = 8%

Interest = (P × R × T)/100

Interest = (2650 × 8 × 1)/100

Interest = Rs 212

Amount = Principal + Interest

Amount = Rs 2650 + Rs 212

Amount = Rs 2862

Compound interest = Rs 150 + Rs 212

Compound interest = Rs 362

Donating blood is a humanitarian act as per a survey 16000 blood donors are registered with Red Cross in Delhi and this number of donors increase s at the rate of5% every six months. a. how many donors would be there at the end of 3/2 years? ​

Answer»

Answer:

1 whole 1 by 2 YEARS is assumed to be 1.5 years i.e. 6 months * 3

After first 6 months DONORS will be: 16000 (1 +  r/100) = 16000 (1 + 5/100) = 16800

After next 6 months donors will be: 16800 (1 +  r/100) = 16800 (1 + 5/100) = 17640

After next 6 months donors will be: 17640 (1 +  r/100) = 17640 (1 + 5/100) = 18522

So, number of donors after 1.5 year will be 18522

A wire is in the shape of a rectangle. Its length is 40 cm and breadth is 22 cm. If the same wire is rebent in the shape of a square, what will be the measure of eachside? Also find which shape encloses more area and by how much?​

Answer»

⭐ Question

A wire is in the shape of a RECTANGLE. Its LENGTH is 40 cm and breadth is 22 cm. If the same wire is rebent in the shape of a SQUARE, what will be the measure of each SIDE. Also find which shape ENCLOSES more area?

{\underline{\bf { Given \: that } }}

  • A wire is in the shape of a rectangle has length of 40 cm and breadth of 22 cm.

{\underline{\bf { To \: find: } }}

  • If the same wire is rebent in the shape of a
  • square, what will be the measure of each side.

  • Also find which shape encloses more area and by how much?

{\underline {\bf { Solution : } }}

According to question-

\rm\blue {Perimeter \: of \: rectangle = Perimeter \: of \: square }

\rm { \therefore 2(Length + Breadth) = 4 \times Side }

\rm { \longrightarrow 2 (40 + 22) = 4 \times Side }

\rm { \longrightarrow 2 \times 62 = 4 \times Side }

\rm { \longrightarrow 124 = 4 \times Side }

\rm { \longrightarrow  Side = \dfrac{124}{4}}

\rm\red { Side  = 31 cm}

Now,

\rm {\implies Ar. \: of \:rectangle = length \times breadth }

\rm {\implies Ar. \: of \:rectangle = 40 \times 22 = 880 {cm}^{2} }

and,

\rm { \implies Area \: of \: square = {(Side)}^{2} }

\rm {  \implies 31 \times 31 = 961 {cm}^{2} }

\rm\purple { 880 {cm}^{2} < 961 {cm}^{2} }

Therefore, the square-shaped wire encloses more area.
