what is the total no of factors of 16!?
solutn gvn=>
16!=1*2*3*4*5*6*7*8*9*10*11*12*13*14*15*16
=2*3*2*2*5*2*3*7*2*2*2*3*3*2*5*11*2*2*3*13*2*7*3*5*2^4
2^15*3^6*5^3*7^2*11*13
So no. Of factor =16*7*4*3*2*2
=448*12
= 53 76

guys why have u multiplied the number of factors. it is asked to find the total number of factors n 16!. shouldn't we add the number of factors to get the total number of factors????

Reply Like? Yes (1) | No

(10 years ago)

look into some small example and observe it .
let it be 4 = 2^2
so total no. of factors is equal to 3. i.e. 1,2,4
similarly for 12=2^2 * 3^1
total factors 3*2 i.e 6 .and factors are 1,2,3,4,6,12 hope you get the logic

– A newspaper agent sells TOI, IE and Herald in equal number to 302 people.7 get IE and Herald, 12 get TOI and IE, 9 get TOI and Herald and 3 get all three.
45. How many get exactly one paper?
1. 280 2. 327 3. 109 4. None of these

From the given info, we can derive
n(IE nd H only) = n(IE n H) - n(IE n H n TOI) => 7-3 = 4
n(IE n TOI only) = 12-3 = 9
n(H n TOI only) = 9-3 = 6
Also it is given that the papers sold in equal number...
So No. of papers in each category is same...
IE+(4+9+3) = H+(4+6+3) = TOI+(9+6+3) = say a constant "k"
n(IE only) = k-16
n(H only) = k-13
n(TOI only) = k-18
From 45th problem, n(IE)+n(H)+n(TOI) = 280
So k-16+k-13+k-18 = 280
k = 109
So no. of papers issued in each category is 109... [Total of 109*3=327 papers]
n(IE only) = 109 - 16 = 93
n(TOI only) = 109 - 18 = 91
n(H only) = 109 - 13 = 96

45)
No. of people getting exactly one paper ll be n(IE)+n(H)+n(TOI)
n(IE)+n(H)+n(TOI) = Total - [n(IE n H) + n(IE n TOI) + n(TOI n H) + n(IE n H n TOI)
=> 302 - [4+9+6+3] => 302 - 22 = 280
Ans : 1) 280

46)
n(TOI nd IE but not H) = 91+93+12-3 = 193
So % of people getting TOI nd IE not H = 193*100/302 = 63.90 = 64% approximately
Ans : 2) 64%

47)
n(TOI nd IE only) = 9
n(TOI n H only) = 6
n(IE n H only) = 4
Ratio => 9 : 6 : 4
Ans : 3) 9 : 6 : 4

48)
n(IE n H only) = 4
n(IE only) = 93
Difference = 93-4 = 89
Ans : 4) None of these

49)
n(TOI only) = 91
Ans : 2) 91

Letbfor 1st case: CP be 100 n after 20% profit Sp become 120

For 2nd case let CP for 1000 g be 100 but due to stealing in weight... 800g costs 100... so if he wud have sold 1000g then hw wud get (100/800)*1000=125

3rd case: let sp of 1000g pure matter be 100 tgen after addition of 20 % impurity it becomes 1240g... now agn we have to find the new sp.. it becomes 124

Then for last case:

Let 1000g costs 100 then after 10% reducn in weight... the new weightbwud be 900 which he will sell at 10% profit I.e 110

So for 10p0 g he will earn (110/900)*100=122.22 so now u can arrange

as per day increase is 25
1st day amount/per day increase =225/25=9(now consider 9 as initial )
final amount /per day increase =9450/25=378(divide it by 9 as nine is take as initial no )
378/9=42

In a rare coin collection, there is one gold coin for every three non-gold coins. 10 more gold coins are added to the collection and the ratio of gold coins to non-gold coins would be 1 : 2. Based on the information, the total number of coins in the collection now becomes

A.90
B.80
C.60
D.50

Reply Like? Yes | No

(10 years ago)

Answer = 90
Solution:
Assuming number of gold coins = x
As per the question if gold coins = x then non gold coins = 3x
If 10 more gold coins are added number of gold coins = x+10
Number of non gold coins would still be = 3x

As per the given information in question: (x+10)/3x = 1/2
Solving we get
=> 2x+20 = 3x
x = 20
Total Coins Initially = x+ 3x = 20+60 =80
Total Coins Now = x+10+3x = 90

Like? Yes (2) | No

(10 years ago)

Ans is A.90
Ratio in Beginning=x:3x; Ratio after adding coins =y:2y
x+10:3x=y:2y
Equating we get x, y
Y=30 so,
Total No of Coins=Y+2y=90

There is a game between A and B.there are 100 sticks..one can maximum take 6 sticks and atleast 1 sticks.the person who take the stick finally consider as a winner.if A starts a game ,is there any winning chance for A,if yes what is that??

Reply Like? Yes (4) | No

(10 years ago)

Yes A has a chance to win by applying following logic.
IfA starts the game he needs to choose max + min no. Of coins I.e.7
Later on after every chance of B ,A needs to choose (max + min -N no. Of coins where N = no.of coins chosen by B.
By this way A can probably win.

I think time is a major concern for every next maths student.for this there are many reasons.
First of all I will say practice matters.by coming across different problems and their logics one can increase their speed.
And secondly one should be fast with their calculations and applying shortcuts .

A cistern has a leak that can empty it in 8hr.An inlet pipe with a capaciity of 60 litres per hour is turned on.When the leak and inlet tap are turned on,the cistern filled with water is emptied in 12 hrs.What is the capacity of the cistern?

Reply Like? Yes | No

(10 years ago)

As per the question
Capacity of cistern + Amount of water added by inlet in 12 hours - Amount of water removed by leak =0
Assuming capacity of cistern = x

x + 60*12 - (x/8)*12 = 0
Solving we 0.5x = 720
x = 1440

@Sasikumar... I dont understand the question... I think the the problem is about remainder or something else... Bcozzz the value of 4^61 ll be very big... We cant calculate that...
4^61 + 4^62 + 4^63 + 4^64
Take 4^61 common outside
4^61(1 + 4^1 + 4^2 + 4^3)
4^61 (1 + 4 + 16 + 64)
4^61 * 85
