2.	How many positive integers n are there such that 3sns 100 and x +x+1 is divisible by x +x+1?
Answer» ANSWER: hey mate!! here is your answer Step-by-step explanation: Let A n =x(x n−1 −na n−1 )+a n (n−1) For n = 2, A 2 =x(x−2a)+a 2 =x 2 −2axa 2 =(x−a) 2 . Thus A 2 is divisible by (x−a) 2 . Now assume that A m is divisible by (x−a) 2 for m ≥ 2, that is, assume A m =x(x m−1 −ma m−1 )+a m (m−1) =(x−a) 2 F (x) so that x m =mxa m−1 −a m (m−1)+(x−a) 2 f(x) We then have A m−1 =x[x m −(m+1)a m ]+a m+1 m =x.x m −(m+1)xa m +ma m,+1 =x[mxa m−1 −a m (m−1)+(x−a) 2 f(x)] −(m+1)xa m +ma m+1 by =ma m−1 [(x 2 −2xa+a 2 )+x(x−a) 2 f(x)] =ma m−1 ((x−a) 2 +x(x−a) 2 f(x) =(x−a) 2 [ma m−1 +xf(x)], After simplification. This shows that A m+1 is divisible by (x−a) 2 . Hence by INDUCTION, A n is divisible by (x−a) 2 for all positive INTEGERS n > 1.

Thus A

But B invests 7,500 and atthe end of 4 months 12,500 more but withdraws* 7,500 at the end of 6 months more. At theAns. I 2.600 each) end of the year the profit they got was 4,725. Find their shares.Ans. (A2,620, B = 2,205]ham future profits as per effective capital
Answer» Solution :- → A = 15000 for 8 months + 20000 for 4 months . → B = 7500 for 4 months + (12500 + 7500) for 2 months + (12500 + 7500 - 7500) for 6 months . So, → Ratio of Profit of A and B = (15000 * 8 + 20000 * 4) : (7500 * 4 + 20000 * 2 + 12500 * 6) = (120000 + 80000) : (30000 + 40000 + 75000) = 200000 : 145000 = 200 : 145 = 40 : 29 . Now, Let us ASSUME that, share of profit of A and B was 40X and 29x . then, → TOTAL share = 40x + 29x = 69x . therefore, → 69x = 4725(given) → x = 4725/69 = 68.47 Hence, → Profit share of A = 40x = 40 * 68.47 = Rs.2738.8 . → Profit share of B = 29x = 29 * 68.47 = Rs.1985.6 .

Find their shares.Ans. (A2,620, B = 2,205]ham future profits as per effective capital

Answer»

Solution :-

→ A = 15000 for 8 months + 20000 for 4 months .

→ B = 7500 for 4 months + (12500 + 7500) for 2 months + (12500 + 7500 - 7500) for 6 months .

So,

→ Ratio of Profit of A and B = (15000 * 8 + 20000 * 4) : (7500 * 4 + 20000 * 2 + 12500 * 6) = (120000 + 80000) : (30000 + 40000 + 75000) = 200000 : 145000 = 200 : 145 = 40 : 29 .

Now, Let us ASSUME that, share of profit of A and B was 40X and 29x .

then,

→ TOTAL share = 40x + 29x = 69x .

therefore,

→ 69x = 4725(given)

→ x = 4725/69 = 68.47

Hence,

→ Profit share of A = 40x = 40 * 68.47 = Rs.2738.8 .

→ Profit share of B = 29x = 29 * 68.47 = Rs.1985.6 .

Step-by-step explanation:

$\huge\boxed{\boxed{\boxed{\red{\underbrace{\orange{\overbrace{\dag ANSWER \dag}}}}}}}$

$\large{\red{\underbrace{●SOLUTION●}}}$

➡️Let the PRESENT age of REHMAN =x
3 YEARS ago Rehman’s age =(x–3) years
5 years later Rehman’s age =(x+5) years.
Now, according to the condition,
(x–3)1+(x+5)1=31
(x–3)(x+5)(x+5+x–3)=31
(x2–3x+5x–15)(2x+2)=31
x2+2x–15=6x+6
x2–4x–21=0
(x+3)(x–7)=0
Either,x+3=0 Or, x–7=0
Thus, x=7 or –3; but age cannot be negative.
HENCE the present age of Rehman is 7 years.
