Answer» The speed of the latter is 20 km/h Step-by-step explanation: Let the speed of the girl going from B to A be v km/hr The DISTANCE between A to B = AB Let the girl from A has travellevd distance = d before meeting the girl from B According to the question Girl from A takes 16 hours and girl from B takes 25 hours after they meet to reach their destination Speed of girl from A = 25 km/hr Using Distance = Speed × Time $AB-d={25}\times{16}$ Again $d=25\times v$ Dividing both we get $\frac{AB-d}{d}=\frac{25\times 16}{25\times v}$ $\implies \frac{AB}{d}-1=\frac{16}{v}$ ....... (1) If they meet after time t Then in time t, the girl from A has travelled distance = d And the girl from B has travelled distance = AB - d Thus $d=25\times t$ And $AB-d=v\times t$ From the above two equations $\frac{AB-d}{d}=\frac{vt}{25t}$ $\implies \frac{AB}{d}-1=\frac{v}{25}$ ...... (2) From equations (1) and (2) $\frac{16}{v}=\frac{v}{25}$ $\implies v^2=16\times 25$ $\implies v=\sqrt{16\times 25}=4\times 5=20$ km/h Therefore, the speed of girl from B is 20 km/h Hope this answer is helpful.

Two girls move in opposite directions, one from A to B and other from B to A. The girl from A reaches the destination in 16 hrs and girl from B reaches her destination in 25 hrs, after having met. If former's speed is 25 km/hr, what will be the speed of latter?

Answer»

The speed of the latter is 20 km/h

Step-by-step explanation:

Let the speed of the girl going from B to A be v km/hr

The DISTANCE between A to B = AB

Let the girl from A has travellevd distance = d before meeting the girl from B

According to the question

Girl from A takes 16 hours and girl from B takes 25 hours after they meet to reach their destination

Speed of girl from A = 25 km/hr

Using Distance = Speed × Time

$AB-d={25}\times{16}$

Again

$d=25\times v$

Dividing both we get

$\frac{AB-d}{d}=\frac{25\times 16}{25\times v}$

$\implies \frac{AB}{d}-1=\frac{16}{v}$ ....... (1)

If they meet after time t

Then in time t, the girl from A has travelled distance = d

And the girl from B has travelled distance = AB - d

Thus

$d=25\times t$

And $AB-d=v\times t$

From the above two equations

$\frac{AB-d}{d}=\frac{vt}{25t}$

$\implies \frac{AB}{d}-1=\frac{v}{25}$ ...... (2)

From equations (1) and (2)

$\frac{16}{v}=\frac{v}{25}$

$\implies v^2=16\times 25$

$\implies v=\sqrt{16\times 25}=4\times 5=20$ km/h

Therefore, the speed of girl from B is 20 km/h

Hope this answer is helpful.

28.	the denominator of rational no is greater than its numerator by 7. if the mumerator is increased by 17 and the deniminator decreased by 6 ,the new no becomes 2. find the original number
Answer» LET the numerator be 'X' Thus, denominator = (x + 7) Thus, fraction = x/(x+7) According to the question, NEW Numerator = x + 17 New denominator = x + 7 - 6 = x + 1 New Fraction = 2 => (x+17)/(x+1) = 2 On cross-multiplying we get, x + 17 = 2(x+1) => x + 17 = 2x + 2 => 2x - x = 17 - 2 => x = 15 Thus original numerator = 15 and original denominator = 15 + 7 = 22 Thus, original fraction = 15/22

28.

the denominator of rational no is greater than its numerator by 7. if the mumerator is increased by 17 and the deniminator decreased by 6 ,the new no becomes 2. find the original number

Answer»

LET the numerator be 'X'

Thus, denominator = (x + 7)

Thus, fraction = x/(x+7)

According to the question,

NEW Numerator = x + 17

New denominator = x + 7 - 6 = x + 1

New Fraction = 2

=> (x+17)/(x+1) = 2

On cross-multiplying we get,

x + 17 = 2(x+1)

=> x + 17 = 2x + 2

=> 2x - x = 17 - 2

=> x = 15

Thus original numerator = 15 and

original denominator = 15 + 7 = 22

Thus, original fraction = 15/22

A shop is sold at 30% profit, the amount of brokerage at the rate of 3/4% amounts to rs. 73,125.find cost of the shop.

Answer»

Given:

Profit obtained on SELLING a shop = 30%

Amount of brokerage at 3/4% = RS 73,125

To FIND:

The COST of the shop

Calculation:

Let the cost price(C.P) of the shop is ‘x’

Selling price of the shop = x + (30% of x)

= 1.30x

Amount of brokerage at 3/4% = Rs 73,125

=> (3/400)×1.30x = 73,125

3.9x = 73,125 × 400

3.9x = 29,250,000

x = 7,500,000

The cost of the shop is 7,500,000

let the no. of STAMPS on ankush be 'x'

therefore,

no. of stamps on ram= 4x/5

(no.of stamps on ankush) + (no. of stamps on ram) = 4500

x+(4x/5)=4500

(TAKING L.C.M. of 5 & 1)

(5x+4x)/5=4500

9x/5= 4500

x=4500*5/9

x=2500

hence, .

no of stamps on ankush=2500

no. of stamps on ram =2000

42.	If a and b are two prime numbers then find HCF(a,b)
Answer» A prime number ALWAYS has 1 and itself as a factor. If the prime numbers aren't common, they won't have each other as a factor. So the two prime numbers have 1 as a common. The HCF(a,b) becomes 1.

8x^2-230x+750=0 by completing the square

Answer»

ANSWER:

Here's the answer:

8x^2-230x+750=0

=>2(4x^2-115x+375)=0

=>(2x)^2 - 2 × 2x × 115/4 +(115/4)^2 - (115/4)^2 + 375=0

=>(2x-115/4)^2 - 13225/16 +375=0

=>(2x-115/4)^2 - 13225+6000/16=0

=>(2x-115/4)^2 -7225/16=0

=>(2x-115/4)^2=7225/16

=>2x-115/4=√7225/16

=>2x=85/4+115/4

=>2x=200/4

=>2x=50

=>x=25
