Hello mate.... 1+2+3=6.......(digit sum) Total=1359 1st share= (1*1359)/6 =226.5 2nd share= (2*1359)/6 =453 3rd share=(3*1359)/6 =679.5 Hope it helps....

Let common multiple is x

Then three number are x, 2x and 3x
As per given condition

x + 2x + 3x = 1359
6x = 1359

x = 1359/6 = 226.5

So, numbers are 226.5, 453, 679.5

Yogita Ingle 5 years, 5 months ago

Let nth term of the given AP be the first negative term.

AP = 24 , 21 , 18

Here,

First term ( a ) = 24

Commmon difference ( d ) = 21-24 = -4.
Then , Tn <0=> { a + ( n - 1 ) × d } <0
=> { 24 + ( n - 1 ) × -3 } <0

=> 27 - 3n <0

=> 27 < 3n

=> 3n > 27

=> n = 9.

n = 10

Hence,

The 10th term is the first negative term of the given AP.

Yogita Ingle 5 years, 5 months ago

Let us assume √2 is rational number.
a rational number can be written into he form of p/q
√2=p/q
p=√2q
Squaring on both sides
p²=2q²__________(1)
.·.2 divides p² then 2 also divides p
.·.p is an even number
Let p=2a (definition of even number,'a' is positive integer)
Put p=2a in eq (1)
p²=2q²
(2a)²=2q²
4a²=2q²
q²=2a²
.·.2 divides q² then 2 also divides q
Both p and q have 2 as common factor.
But this contradicts the fact that p and q are co primes or integers.
Our supposition is false
.·.√2 is an irrational number.

Viren Davra 5 years, 5 months ago

Given:- a circle with center O. a perellelogram ABCD touching the circle at points P, Q, R and S. To prove:- ABCD is rhombus. Proof :- a rhombus is a perellelogram with all sides equal. So, we have to prove all sides equal. In perellelogram ABCD, AB=CD & AD=BC, ( opposite sides of perellelogram are equal.)..................(01) From theorem 10.2, length of tangent drown from external point of circle are equal. Hence, AP = AS,........... (02) BP = BQ,............(03) CR = CQ, ............(04) DR = DS. ............(05) Adding equation (02) + (03) + (04) + (05) AP + BP + CR + DR = AS + BQ + CQ + DS (AP + BP)+(CR + DR) = (AS + DS)+(BQ + CQ) AB + CD = AD + BC But from equation (01) : AB=CD & AD=BC AB + AB = AD + AD 2AB = 2AD AB = AD So, AB = AD & AB=CD & AD=BC. So, AB = CD = AD = BC. So, ABCD is a perellelogram with all sides equal, There fore. ABCD is rhombus. Hence proved.
