Answer»

Answer:

33.33% and 66.67%

Step-by-step EXPLANATION:

Total NUMBER of students = 177.

Number of girls after 5% leave = 120*95/100 = 114.

New total number of students = 171.

% of boys = 100*57/171 = 33.33%

How many terms of the series 15+12+9... must be taken to make 15?Explain with double answers.

Answer»

Answer:

10

Step-by-step EXPLANATION:

Given

How many TERMS of the SERIES 15+12+9... must be taken to make 15?

Given

15 + 12 + 9 + …..

To find using A.P

To find n, a = 15, d = 12 – 15 = - 3

Sn = n/2 [ 2a + (n – 1)d]

Now Sn = 15

n/2 [2(15) + (n – 1)(-3)] = 15

n(30 – 3n + 3) = 30

n(33 – 3n) = 30

33N – 3n^2 = 30

3n^2 – 33n + 30 = 0

n^2 – 11n + 10 = 0

(n – 1)(n – 10) = 0

n = 1, 10

So n = 10

The numerator of a fraction is 5 less than the denominator. If 9 is added to both the numerator and denominator, it becomes 2/3 .Find the rational number.

Answer»

Answer:

The rational number is $\sf{\dfrac{1}{6}}$

Step-by-step EXPLANATION:

Given :

The numerator of a fraction is 5 less than the denominator

If 9 is added to both the numerator and denominator, it becomes 2/3

To find :

The rational number

Solution :

LET the -

Numerator = (y)
Denominator = (y + 5)

⇒ $\sf{\dfrac{y + 9}{(y + 5) + 9} = \dfrac{2}{3}}$

⇒ 3(y + 9) = 2(y + 5 + 9)

⇒ 3y + 27 = 2(y + 14)

⇒ 3y + 27 = 2y + 28

⇒ 3y - 2y = 28 - 27

⇒ y = 1

Numerator = 1

$\rule{300}{1.5}$

★ Denominator =

⇒ y + 1

⇒ 6

The rational number formed = $\sf{\dfrac{1}{6}}$

$\therefore$ The rational number is $\sf{\dfrac{1}{6}}$

50.	Sum of 4 terms in AP is 28 and the product of 1 and 4 term to product of 2 and 3 is 5:6 find the no
Answer» Step-by-step EXPLANATION: LET the for Numbers be (a-3d), (a-d), (a+d) and (a+3d), then according to the question, we have (a-3d)+(a-d)+(a+d)+(a+3d)=28, then 4a=28, then a=7, ALSO (a-3d)(a+3d)/(a-d)(a+d) = 5/6, 6(a²-9d²)=5(a²-d²) , 6a²-54d²=5a²-5d², then 6a²-5a²=-5d²+54d², then 6a²-5a²=-5d²+54d², a²=49d², 7²=49d², 49=49d², then d²=1, hence d=1, therefore 1st number=(7-3×1)=7-3=4, 2nd number=(7-1)=6, 3rd number=(7+1)=8, 4th number=(7+3×1)=7+3=10

50.

Sum of 4 terms in AP is 28 and the product of 1 and 4 term to product of 2 and 3 is 5:6 find the no

Answer»

Step-by-step EXPLANATION:

LET the for Numbers be (a-3d), (a-d), (a+d) and (a+3d),

then

according to the question, we have

(a-3d)+(a-d)+(a+d)+(a+3d)=28,

then

4a=28,

then

a=7,

ALSO

(a-3d)(a+3d)/(a-d)(a+d) = 5/6,

6(a²-9d²)=5(a²-d²) ,

6a²-54d²=5a²-5d²,

then

6a²-5a²=-5d²+54d²,

then

6a²-5a²=-5d²+54d²,

a²=49d²,

7²=49d²,

49=49d²,

then

d²=1,

hence

d=1,

therefore

1st number=(7-3×1)=7-3=4,

2nd number=(7-1)=6,

3rd number=(7+1)=8,

4th number=(7+3×1)=7+3=10
