6.

Use Euclid's division algorithms to find the HCF of 657 and 953

Answer»

LET a=657 b=953

we KNOW a=b×q+r

953÷657=296

953=657×1+296

296÷657=65

657=296×2+65

296÷65=36

296=65×4+36

65÷36=29

65=36×1+29

36÷29=7

36=29×1+7

29÷7=1

29=7×4+1

7÷4=3

7=4×1+3

3÷4=1

4=3×1+1

3÷1=3

3=3×1+0

so hcf=3

And the digit in the tens place be y. Then x = 3y and the NUMBER = 10y + x The number obtained by reversing the digits is 10X + y. If 36 is added to the number, digits interchange their PLACES, THEREFORE, We have: 10y + x + 36 = 10x + y ➠ 10y – y + x + 36 = 10x + y - y ➠ 9y + x – 10x + 36 = 10x - 10x ➠ 9y - 9x + 36 = 0 or, 9x - 9y = 36 ➠ 9(x - y) = 36 ➠ 9(x - y)/9 = 36/9 ➠ x - y = 4 ……….

In a two digit number. The units digit is thrice the tens digit. If 36 is added to the number, the digits interchange their place. Find the number.

Answer»

⠀⠀⠀ ՏϴᏞႮͲᏆϴΝ

$\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$

Let the digit in the units place is x.
And the digit in the tens place be y.

Then x = 3y and the NUMBER = 10y + x

The number obtained by reversing the digits is 10X + y.

If 36 is added to the number, digits interchange their PLACES,

THEREFORE, We have:

10y + x + 36 = 10x + y

➠ 10y – y + x + 36 = 10x + y - y

➠ 9y + x – 10x + 36 = 10x - 10x

➠ 9y - 9x + 36 = 0 or, 9x - 9y = 36

➠ 9(x - y) = 36

➠ 9(x - y)/9 = 36/9

➠ x - y = 4 ………. (i)

Substituting the value of x = 3y in equation (i),

We get:

3y - y = 4

➠ 2y = 4

➠ y = 4/2

➠ y = 2

Substituting the value of y = 2 in equation (i),

We get:

x - 2 = 4

➠ x = 4 + 2

➠ x = 6

Hence, the number becomes 26.

Answer» Step-by-step explanation: रश्नांकरता A / C पुढील प्रश्नासह आम्हाला प्रदान करण्यात आले आहे ----- एका हत्तीची किंमत = 5 रु. दिलेल्या, एक घोडा किंमत = 1 रे. दिलेले, 20 उंटांची किंमत = 1 रे. आम्ही प्राणी संख्या ज्या 100 रुपये मध्ये खरेदी करता येते गणना करणे आवश्यक आहे. उपाय पुढीलप्रमाणे आहे: ---- 20 उंटांची किंमत = 1 रे. म्हणून, एक उंटची किंमत = 1/20 रे असेल. = 0.05 रे. गृहित धरा, 80 ऊंट खरेदी केले जाऊ शकतात (एक गोल आकृती रक्कम येणे) तर 80 उंटांची किंमत = 0.05 X 80 = रु .4 होईल. गृहीत धरा, आम्ही 19 हत्ती विकत घेऊ शकतो नंतर, 19 हत्तीची किंमत = 5 × 19 = रु. 95 तसेच, ए / क्यू, एक घोडा किंमत = 1 रे असेल. आता किंमती वाढवू ---- रू. 4 + रु. 95 + 1 रे = रु. 100 आता. एकूण जनावरांची संख्या रु. 100 = 80 ऊंट असतील + 19 हत्ती + 1 घोडा म्हणून, एकूण 80 उंट, 19 हत्ती आणि 1 घोड्यांची एकूण रक्कम शंभर रुपये ************************************************** Hope it helps and solves your QUERY!!

100 रुपयाला 100 प्राणी घेऊन दाखवा 1 रुपयाला 1 घोडा, 5 रुपयाला 1 हत्ती, 1 रुपयाला 20 उंट

Answer»

Step-by-step explanation:

रश्नांकरता A / C पुढील प्रश्नासह आम्हाला प्रदान करण्यात आले आहे -----

एका हत्तीची किंमत = 5 रु. दिलेल्या,

एक घोडा किंमत = 1 रे. दिलेले,

20 उंटांची किंमत = 1 रे.

आम्ही प्राणी संख्या ज्या 100 रुपये मध्ये खरेदी करता येते गणना करणे आवश्यक आहे.

उपाय पुढीलप्रमाणे आहे: ----

20 उंटांची किंमत = 1 रे. म्हणून,

एक उंटची किंमत = 1/20 रे असेल. = 0.05 रे.

गृहित धरा, 80 ऊंट खरेदी केले जाऊ शकतात (एक गोल आकृती रक्कम येणे) तर 80 उंटांची किंमत = 0.05 X 80 = रु .4 होईल.

गृहीत धरा, आम्ही 19 हत्ती विकत घेऊ शकतो नंतर, 19 हत्तीची किंमत = 5 × 19 = रु. 95

तसेच, ए / क्यू, एक घोडा किंमत = 1 रे असेल.

आता किंमती वाढवू ---- रू. 4 + रु. 95 + 1 रे

= रु. 100 आता.

44.	The average age of 15 people in a group is 24 years old. Then, when one person grew, the average was 23. If so, how old is the new person?
Answer» Before the new person came, we had, Age of all persons÷Number of persons=24 Lets say that the previous number of PEOPLE was 'x'. Then, x/15=24 So, x=360 Now, after one more person came, The number of people became 16. The TOTAL age WOULD BECOME 360+y, where y is the age of new person. So, according to the question, (360+y)÷16=23 360+y=368 y=8 So, the age of new person is 8 years.

The average age of 15 people in a group is 24 years old. Then, when one person grew, the average was 23. If so, how old is the new person?

Answer»

Before the new person came, we had,

Age of all persons÷Number of persons=24

Lets say that the previous number of PEOPLE was 'x'.

Then,

x/15=24

So, x=360

Now, after one more person came,

The number of people became 16.

The TOTAL age WOULD BECOME 360+y,

where y is the age of new person.

So, according to the question,

(360+y)÷16=23

360+y=368

y=8

So, the age of new person is 8 years.
