Five years ago Nuri was thrice as old as Sun 10 year letter no he will be twice as old as Sun how old are Nuri and Sonu

Answer»

$\large{\underline{\bf{\red{Correct\:Question:-}}}}$

Five years ago, Nuri was thrice as old as Sonu. Ten years later, Nuri will be twice as old as Sonu. How old are Nuri and Sonu.

$\large{\underline{\bf{\blue{Given:-}}}}$

✦ Five years ago Nuri was thrice as old as Sonu.
✦ 10 years later Nuri will be twice as old as Sonu.

$\large{\underline{\bf{\blue{To\:Find:-}}}}$

➝ present AGE of Nuri and Sonu.

$\huge{\underline{\bf{\green{Solution:-}}}}$

LET the present age of Nuri be X years.

and, Let the present age of Sonu be y years.

Five years ago Nuri was thrice as old as Sonu.

➝ Age of Nuri = (x -5) year's

➝ Age of Sonu = (y -5) year's

According to 1st condition:-

➝ ( x -5 )= 3(y -5)

➝ (x -5) = 3y -15

➝ x - 3y = -10 .............(i)

Now,

10 years later Nuri will be twice as old as Sonu.

Age of Nuri = x+10 years

Age of Sonu = y +10 years

According to 2nd condition:-

➝ (x+10) = 2(y+10)

➝ x+10 = 2y + 20

➝ x - 2y = 10 .............(ii)

From equation (i) and (ii) , we get,

x - 3y = -10

x- 2y = 10

-- ⠀+⠀⠀--

⠀⠀-y = -20

we get, y = 20

putting value of y in equation (i)

➝ x - 3y = -10

➝ x -3×20 = -10

➝ x - 60 = -10

➝ x = 50

Hence,

Age of Nuri is x = 50 year's

Age of Sonu y = 20 year's.

Answer» LET the principal, P = Rs.x, r = 10%, t = 1 year Using S.I. = Prt/100, S.I. = Rs.(x × 10 × 1)/100 =Rs.x/10 No of conversion PERIOD, n = 2 × 1 = 2, r = 10%/2 = 5% per conversion period, P = x, Using C.I. = P [(1 + r/100)n 1], C.I. = Rs.x [(1 + 5/100)2 1] = Rs.x(21/20 ×21/20 1) = Rs.x(441/400 1) = Rs.(41/400)x As per problem, C.I. S.I. = Rs.180 Or, Rs.(41/400)x Rs.x/10 = 180 Or, Rs.(41/400 1/10)x = 180 Or, Rs.x/400 = 180 Or, x = Rs.180 × 400 = Rs.7200

11.

The difference between the compound interest for a year payable half-yearly and the simple interest on a certain sum of money lent out at 10% for a year is rupees 15 find the compound interest.

Answer»

LET the principal, P = Rs.x, r = 10%, t = 1 year

Using S.I. = Prt/100,

S.I. = Rs.(x × 10 × 1)/100 =Rs.x/10

No of conversion PERIOD, n = 2 × 1 = 2,

r = 10%/2 = 5% per conversion period, P = x,

Using C.I. = P [(1 + r/100)n 1],

C.I. = Rs.x [(1 + 5/100)2 1]

= Rs.x(21/20 ×21/20 1)

= Rs.x(441/400 1)

= Rs.(41/400)x

As per problem, C.I. S.I. = Rs.180

Or, Rs.(41/400)x Rs.x/10 = 180

Or, Rs.(41/400 1/10)x = 180

Or, Rs.x/400 = 180

Or, x = Rs.180 × 400 = Rs.7200

12.	Three rational number between 1/4 and 3/4
Answer» Answer: Hey Mate Your Answer is 1/2, 5/8, 11/16 Step-by-step EXPLANATION: Let a=1/4 and B=3/4 we know that a rational number between two rational numbers is the AVERAGE of the two rational numbers so 1 rational number between a and b is (a+b)÷2 = (1/4+3/4)÷2 = (4/4)÷2 = 1/2 now let a=1/2 and b=3/4 rational number between 1/2 and3/4 is = (1/2+3/4)÷2 = (2+3)/4÷2 = 5/4/2 = 5/42 = 5/8 now let a=5/8 and b=3/4 rational number between 5/8 and 3/4 is = (5/8+3/4)÷2 = (5+6)/8÷2 = 11/8/2 = 11/82 = 11/16 hope this answer helps you

12.

Three rational number between 1/4 and 3/4

Answer»

Answer:

Hey Mate Your Answer is 1/2, 5/8, 11/16

Step-by-step EXPLANATION:

Let a=1/4 and B=3/4

we know that a rational number between two rational numbers is the AVERAGE of the two rational numbers

so 1 rational number between a and b is (a+b)÷2

= (1/4+3/4)÷2

= (4/4)÷2

= 1/2

now let a=1/2 and b=3/4

rational number between 1/2 and3/4 is

= (1/2+3/4)÷2

= (2+3)/4÷2

= 5/4/2

= 5/4*2

= 5/8

now let a=5/8 and b=3/4

rational number between 5/8 and 3/4 is

= (5/8+3/4)÷2

= (5+6)/8÷2

= 11/8/2

= 11/8*2

= 11/16

28.	Evaluate :i) tan 36°/cot 54°ii) cos 12° - sin 78°iii) cosec 31° - sec 58°
Answer» HELLO FRIEND!!!!!! QUESTION 1: $\frac{ \tan(36) }{ \cot(54) }$ we know the identity that : $\tan(90 - theeta) = \cot(theeta)$ thus, $\tan(36) = \tan(90 - 36)$ $\tan(36) = \cot(54)$ thus equation becomes: $\frac{ \cot(54) }{ \cot(54) }$ $1$ thus answer of question 1 is 1 question 2 $\cos(12) - \sin(78)$ again using same identity, where theeta is 12 degree.... $\cos(12) = \sin(90 - 12)$ $\cos(12) = \sin(78)$ so equation becomes... $\sin(78) - \sin(78)$ which is 0..... thus answer of question 2 becomes 0 question 3 $\csc(31) - \<klux>SEC</klux>(58)$ using same identity ... $\csc(31) = \csc(90 - 59)$ so here there is an ERROR in question...the question should be sec 59 degree ..... $\sec(58)$ $- \sec(58)$ which is 0 thus answer of corrected question 3 would be 0 ..

Evaluate :i) tan 36°/cot 54°ii) cos 12° - sin 78°iii) cosec 31° - sec 58°

Answer»

HELLO FRIEND!!!!!!

QUESTION 1:

$\frac{ \tan(36) }{ \cot(54) }$

we know the identity that :

$\tan(90 - theeta) = \cot(theeta)$

thus,

$\tan(36) = \tan(90 - 36)$

$\tan(36) = \cot(54)$

thus equation becomes:

$\frac{ \cot(54) }{ \cot(54) }$

$1$

thus answer of question 1 is 1

question 2

$\cos(12) - \sin(78)$

again using same identity,

where theeta is 12 degree....

$\cos(12) = \sin(90 - 12)$

$\cos(12) = \sin(78)$

so equation becomes...

$\sin(78) - \sin(78)$

which is 0.....

thus answer of question 2 becomes 0

question 3

$\csc(31) - \<klux>SEC</klux>(58)$

using same identity ...

$\csc(31) = \csc(90 - 59)$

so here there is an ERROR in question...the question should be sec 59 degree .....

$\sec(58)$

$- \sec(58)$

which is 0

thus answer of corrected question 3 would be 0 ..

THANK YOU

. If a, ß are the roots of 7x^2+ ax + 2 = 0 and if ß-a =-13Find the values of a.

Answer»

$\huge\purple{\underline{\underline{\pink{Ans}\red{wer:}}}}$

$\sf{The \ value \ of \ a \ is \ \frac{195+\sqrt105}{16} \ or \ \frac{195-\sqrt105}{16}}$

$\sf\orange{Given:}$

$\sf{The \ given \ quadratic \ equation \ is}$

$\sf{\implies{7x^{2}+ax+2=0}}$

$\sf{\implies{\beta-a=-13}}$

$\sf\pink{To \ find:}$

$\sf{The \ value \ of \ a.}$

$\sf\green{\underline{\underline{Solution:}}}$

$\sf{\implies{\beta-a=-13}}$

$\sf{\implies{\therefore{\beta=-13+a}}}$

$\sf{But \ \beta \ is \ the \ roots \ of \ given}$

$\sf{equation.}$

$\sf{\therefore{Substituting \ \beta \ in \ equation \ will \ give}}$

$\sf{result \ zero.}$

$\sf{\implies{\therefore{7(-13+a)^{2}+a(-13+a)+2=0}}}$

$\sf{\implies{7(169-26a+a^{2})-13a+a^{2}+2=0}}$

$\sf{\implies{1183-182a+7a^{2}-13a+a^{2}+2=0}}$

$\sf{\implies{7a^{2}+a^{2}-182a-13a+1183+2=0}}$

$\sf{\implies{8a^{2}-195a+1185=0}}$

$\sf{Here, \ a=8, \ b=-195 \ and \ c=1185}$

$\sf{By \ formula \ method}$

$\sf{b^{2}-4ac=(-195)^{2}-4(8)(1185)}$

$\sf{\implies{b^{2}-4ac=38025-37920}}$

$\sf{\implies{b^{2}-4ac=105}}$

$\sf{\implies{a=\frac{-b+\sqrt{b^{2}-4ac}}{2a} \ or \ \frac{-b-\sqrt{b^{2}-4ac}}{2a}}}$

$\sf{\implies{a=\frac{195+\sqrt105}{16} \ or \ \frac{195-\sqrt105}{16}}}$

$\sf\purple{\tt{\therefore{The \ value \ of \ a \ is \ \frac{195+\sqrt105}{16} \ or \ \frac{195-\sqrt105}{16}}}}$

Suppose x = 13/ root(19 + 8root3), find the exact value of x^4 - 6x^3 - 2x^2 + 18x + 23/ x^2 - 8x + 15

Answer»

Answer:

5

Step-by-step EXPLANATION:

$x = \frac{13}{\sqrt{19 +8\sqrt{3} } } \\\\Denominator = {\sqrt{19 +8\sqrt{3} } } \\\\= \sqrt{4^2 + \sqrt{3}^2 + 2*4*\sqrt{3} } \\= \sqrt{(4+\sqrt{3})^2 } \\= 4 + \sqrt{3}$

$x = \frac{13}{4+\sqrt{3\\} } \\(Rationalisation)\\\\ \frac{13}{4+ \sqrt{3} } *\frac{4-\sqrt{3} }{4-\sqrt{3} } \\\\\frac{13(4-\sqrt{3) } }{13}$

$x = 4 - \sqrt{3} \\\\\frac{x^4 - 6x^3 - 2x^2+18x+23}{x^2-8x+15} \\\\x^4 =( (4+\sqrt{3}) ^{2} )^2$

$x^4 =( 19 + 8\sqrt{3} )^2\\x^4 = 553 + 304\sqrt{3} \\\\x^3 = (4+\sqrt{3)}^3 \\x^3 = 64 + 3\sqrt{3} + 48\sqrt{3}+36$

$x^3 = 100 +51\sqrt{3} \\\\x^2 = (4+\sqrt{3})^2\\x^2 = 19 + 8\sqrt{3}$

(SUBSTITUTE the VALUES in NUMERATOR)

$(553+304\sqrt{3}) -6(100+51\sqrt{3}) - 2(19+8\sqrt{3}) +18(4+\sqrt{3})+23\\553+304\sqrt{3}-600-306\sqrt{3} -38 - 16\sqrt{3} +72+18\sqrt{3}+23\\ 10\\Denominator = x^2 -8x +15\\(x-3)(x-5)\\$

$(4+\sqrt{3}-3)(4+\sqrt{3}-5)\\(\sqrt{3} + 1)(\sqrt{3} - 1)\\2\\\\Answer = \frac{10}{2} = 5$
