Rubi deposits 250 per month in a post officerecurring deposit account for 3 years. Whatamount will she get on maturity, if the rate ofinterest is 7.5% p.a.?

Answer»

<P>Step-by-step explanation:

p = € 250

n = 3 YEARS

= 12×3

= 36 months

r = 7.5 %

SI = p×n(n+1)/2 × 1/ 12 × r/ 100

= 250 × 36 ×37/2 × 1/12 × 7.5 /100

= € 1083

M.V. =( p × n) + SI

= (250 × 36) + 1083

= 9000 + 1083

= 10083 (ans)

Answer» ANSWER: Other rational number = -71/9 GIVEN: The sum of two rational numbers -22/3. One rational number = 5/9. TO FIND: Other rational number. SOLUTION: LET X be the other rational number. => Sum of two rational numbers -22/3. $\implies \: x + \dfrac{5}{9} = \dfrac{ - 22}{3} \\ \\ \implies \: x \: = \dfrac{ - 22}{3} - \dfrac{5}{9} \\ \\ \implies \: x = \dfrac{ - 66 - 5}{9} \\ \\ \implies \: x = \frac{ - 71}{9}$ Other rational number = -71/9 In this way we can find the rational number. NOTE: Rational number = A number in the form of p/q where p and q are integers and q is not EQUAL to 0 and p and q are CO prime is called rational number.

The sum of two rational numbers -22/3 if one rational numbers is 5/9 what is other number

Answer»

ANSWER:

Other rational number = -71/9

GIVEN:

The sum of two rational numbers -22/3.
One rational number = 5/9.

TO FIND:

Other rational number.

SOLUTION:

LET X be the other rational number.

=> Sum of two rational numbers -22/3.

$\implies \: x + \dfrac{5}{9} = \dfrac{ - 22}{3} \\ \\ \implies \: x \: = \dfrac{ - 22}{3} - \dfrac{5}{9} \\ \\ \implies \: x = \dfrac{ - 66 - 5}{9} \\ \\ \implies \: x = \frac{ - 71}{9}$

Other rational number = -71/9

In this way we can find the rational number.

NOTE:

Rational number = A number in the form of p/q where p and q are integers and q is not EQUAL to 0 and p and q are CO prime is called rational number.

Answer» Step-by-step explanation: 1) questions completed in first week=140 questions completed in second week=182 increased number=182-140=42 percentage increase=increase number / original number X 100% =>(42/140) x 100% =>(3/10) x 100% 3 x 10=30% therefore increase percent =30% 2) grains found in first week=250 grains found in second week=175 difference in grains= 250-175=75 decrease percent =(decrease/original no.) x 100% =(75/250) x 100% =(3/10) x 100% =3 x 10% =30% therefore the decrease percent= 30% 3) original mass of the chocolate bar= 340gms increased by = 15% new mass=340 + 15% first lets FIND out 15 % of 340 =340 x 15% =340 x 15/100 = 34 x 1.5 = 51 now, lets add 340 and 51 to get new value =340+51=391 therefore the new mass of chocolate is 391 grams

Answer»

Step-by-step explanation:

1) questions completed in first week=140

questions completed in second week=182

increased number=182-140=42

percentage increase=increase number / original number X 100%

=>(42/140) x 100%

=>(3/10) x 100%

3 x 10=30%

therefore increase percent =30%

2) grains found in first week=250

grains found in second week=175

difference in grains= 250-175=75

decrease percent =(decrease/original no.) x 100%

=(75/250) x 100%

=(3/10) x 100%

=3 x 10%

=30%

therefore the decrease percent= 30%

3) original mass of the chocolate bar= 340gms

increased by = 15%

new mass=340 + 15%

first lets FIND out 15 % of 340

=340 x 15%

=340 x 15/100

= 34 x 1.5

= 51

now, lets add 340 and 51 to get new value

=340+51=391

therefore the new mass of chocolate is 391 grams

Write the quadratic polynomial whoseSumSum of zeroes is – 3 and sumof thethe Squares of zeroes is 17

Answer»

<P>Step-by-step explanation:

sum= -3

a+b= -3

a^2+b^2=17

(a+b)^2-2ab=17

(-3)^2-2ab=17

9-2ab=17

-2ab=17-9

-2ab=8

ab=8/-2

ab= -4

product=-4

p(X)=x^2-(a+b)X+ab

p(X)=x^2-(-3)X+(-4)

p(X)=x^2+3x-4

49.	The age of the mother is 30 years more than her daughter's age.Ten year hence,the mother's age will become three times the daughters age at that time. What is the daughters present age in years?
Answer» Given : The age of the MOTHER is 30 years more than her DAUGHTER's age. 10 year HENCE,the mother's age will become three TIMES the daughter's age at that time. To find : Present age of daughter . Solution : CONSIDER, Present age of mother = x years Present age of daughter = y years According to the 1st condition :- The age of mother is 30 years more than her daughter's age . $\implies\sf{x=y+30...................(1)}$ According to the 2nd condition :- 10 year hence,the mother's age will become three times the daughter's age at that time. After 10 years, Age of mother = (x+10) years Age of daughter = (y+10) years $\implies\sf{x+10=3(y+10)}$ $\implies\sf{y+30+10=3y+30\:[Put\:x=(y+30)\: from\:eq(1)]}$ $\implies\sf{y+40=3y+30}$ $\implies\sf{y-3y=30-40}$ $\implies\sf{-2y=-10}$ $\implies\sf{y=5}$ Present age of daughter = 5 years Therefore, the present age of daughter is 5 years.

The age of the mother is 30 years more than her daughter's age.Ten year hence,the mother's age will become three times the daughters age at that time. What is the daughters present age in years?

Answer»

Given :

The age of the MOTHER is 30 years more than her DAUGHTER's age.
10 year HENCE,the mother's age will become three TIMES the daughter's age at that time.

To find :

Present age of daughter .

Solution :

CONSIDER,

Present age of mother = x years
Present age of daughter = y years

According to the 1st condition :-

The age of mother is 30 years more than her daughter's age .

$\implies\sf{x=y+30...................(1)}$

According to the 2nd condition :-

10 year hence,the mother's age will become three times the daughter's age at that time.

After 10 years,

Age of mother = (x+10) years
Age of daughter = (y+10) years

$\implies\sf{x+10=3(y+10)}$

$\implies\sf{y+30+10=3y+30\:[Put\:x=(y+30)\: from\:eq(1)]}$

$\implies\sf{y+40=3y+30}$

$\implies\sf{y-3y=30-40}$

$\implies\sf{-2y=-10}$

$\implies\sf{y=5}$

Present age of daughter = 5 years

Therefore, the present age of daughter is 5 years.
