Use formula(x+y/2 where x"=1/7 y"=1/8 so, (1/7+1/8)/2 =((8+7)/56)/2 =(15/56)2 =(15/56)×1/2 =15/56×1/2 =15/112

Sia ? 4 years, 6 months ago

Let the present ages of son and father be x years and (56 - x) years respectively.
Then, (56 - x + 4) = 3(x + 4)
⇒ 4x = 48
⇒ x = 12
So, their present ages are 12 years, 44 years respectively.

Given that l=2w

Perimeter =2(l +w)=66

l+w=33

ANSWER

The sum of the digits of a certain two digit number is 7. Reversing it's digits increases the number by 9. What is the number ?

Posted by Reshmi Das 4 years, 6 months ago

CBSE > Class 08 > Mathematics

1 answers

Sia ? 4 years, 6 months ago

Let,

The units digit = x

The tens digit = 7 - x

Orignal Number :

⇒ 10 (7 - x) + x

⇒ 70 - 10x + x

⇒ 70 - 9x

Digit of the number reversing :

⇒ 10x + (7 - x)

⇒ 10x - x + 7

⇒ 9x + 7

According to the question:

The number with reversed digits increases

The original number by 9 :

So,

⇒ (70 - 9x) + 9 = (9x + 7)

⇒ 70 + 9 - 9x = 9x + 7

⇒ 79 - 9x = 9x + 7

⇒ 79 - 7 = 9x + 9x

⇒ 72 = 18x

⇒ 18x = 72

⇒ x = 72 / 18

⇒ x = 4

The unit digit = 4

The tens digit = 7 - x

⇒ 7 - 4

⇒ 3

The tens digit = 3

Therefore,

The number is 34

ANSWER

The difference of two numbers is 3. Their sum is 13. Find the numbers.

Posted by Reshmi Das 4 years, 6 months ago

CBSE > Class 08 > Mathematics

Sia ? 4 years, 6 months ago

Consider the two numbers as x and y. From the given data, we write:

x−y=3
x+y=13

From the first equation, we determine a value for x.

x−y=3

Add y to both sides.

x=y+3

In the second equation, substitute x with (y+3).

x+y=13

(y+3)+y=13

Open the brackets and simplify.

y+3+y=13

2y+3=13

Subtract 3 from each side.

2y=10

Divide both sides by 2.

y=5

In the first equation, substitute y with 5.

x−y=3

x−5=3

Add 5 to each side.

x=8

Sia ? 4 years, 6 months ago

Multiplying 1/2 by 3/3 and 1/3 by 2/2, we get , . 3/6 and 2/6.

Again multiplying the denominator and nominator of 3/6 and 2/6 by (5+1)= 6,

(2 x 6)/(6 x 6)= 12/36

(3 x 6)/(6 x 6)= 18/36

Therefore, 5 rational numbers between 1/2 and 1/3 are 13/36, 14/36, 15/36, 16/36 & 17/36.
