21.	A is twice as efficient as B and therefore is able to finish a job in 30 days less than B Working together, they can do it in
Answer» Answer: 20 DAYS Step-by-step explanation: A is TWICE as efficient as B i.e EFFICIENCY ratio of A : B = 2:1 efficiency is considered as one day work. Number of days taken by A = (x-30) days Number of days taken by B = x days Total Work done by A = (x-30) * 2 Total Work done by B = x * 1 By equating work done $( x - 30) \times 2 = x$ $x = 60$ Total Work done by A = 30 days Total Work done by B = 60 days $\frac{1}{30} + \frac{1}{60} = \frac{1}{20}$ Together they can do it in 20 days

21.

A is twice as efficient as B and therefore is able to finish a job in 30 days less than B Working together, they can do it in

Answer»

Answer:

20 DAYS

Step-by-step explanation:

A is TWICE as efficient as B

i.e EFFICIENCY ratio of A : B = 2:1

efficiency is considered as one day work.

Number of days taken by A = (x-30) days

Number of days taken by B = x days

Total Work done by A = (x-30) * 2

Total Work done by B = x * 1

By equating work done

$( x - 30) \times 2 = x$

$x = 60$

Total Work done by A = 30 days

Total Work done by B = 60 days

$\frac{1}{30} + \frac{1}{60} = \frac{1}{20}$

Together they can do it in 20 days

43.

The 4th term of an Ap is zero .prove that its AP is 25 th term is tripple its 11th Term

Answer»

To PROVE :

25TH term is TRIPPLE of 11th term

Proof :

t(4) = a+3d = 0

⇒a=-3d

t(25) = a +24d

= -3d +24d

= 21d.

t(11) = a + 10d

= -3d + 10d

= 7d

therefore , t(25) = t(11) × 3

Hence proved !!

If log3729 = xthan value ofx

Answer»

$\bf{\underline{Question:-}}$

if log $\sf _3 (729) = x$ then value of x

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

log $\sf _3 (729) = x$
X = ?

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

Note,

If x and y are positive real numbers and b does not EQUAL to 1,
then $\sf log_b(x) = y$ is equivalent to $\sf b^y = x$ .

Now,

→ $\sf log_3(729) = x$

→ $\sf 3^x = 729$

→ $\sf 3^x = 3^<klux>6</klux>$ { BASES are equal }

Comparing the exponent

→ $\sf x = 6$

$\bf{\underline{Hence:-}}$

The Required Value Of X is 6

50.

Find the value of k,if x=2,y=1 is the solution of the equation 2x +3y=k.

Answer»

Answer:

k = 7

Step-by-step explanation:

Given,

x = 2

y = 1

k = ?

Substitute the values of x and y in 2X + 3y = k,

2(2) + 3(1) = k

4 + 3 = k

k = 7

The value of k is 7.

THANK YOU!! HOPE YOU UNDERSTAND!!!
