All numbers in that set are odd. An odd number plus an odd number is even. 4 odds added together is even, and a fifth will always make it odd. Therefore the sum of 5 numbers from that set can never be 30 as 30 is even.

unit digit in (2^53*7^67*3^95)
please tell me how to solve above problem

Reply Like? Yes | No

(10 years ago)

2^4 =16 , Here unit digit is 6 , It means 2^52 will have unit digit as 6
Therefore 2^53 will have unit digit 2

Similiarly , 7^4 will have unit digit 1, Therefore 7^64 will have unit digit as 1.
so, unit digit of 7^67 will have unit digit 3

similiarly with, 3^95 which will give unit digit 7

Now multiplying unit digit of every number we have,
2*3*7 = 2

A can do a piece of work in 16 days. After working on it for 4 days B joins who can complete work in 32 days. if a earns 1200 how much does B earn ?

Reply Like? Yes | No

(10 years ago)

400

A's 4 days work= 4*(1/16)=1/4
Remaining 3/4 of the work is completed by both A & B
B alone can complete work in 32 days, So B's 1 day work= 1/32
If Both A & B works for 'x' days, then, [(1/16)+(1/32)]*x=3/4 , x=8
A's total work for (4+8)=12 days= 12*(1/16)=3/4
B's total work for 8 days= 8*(1/32)=1/4
As for 3/4 share of the work, A got 1200, so for 1/4 share B will earn=(1/4)*1200/(3/4) =400 Rs.

a product when sold with 10% rebate on the listed price gave a profit of rs 70 what was its cost price?
A.200
B.350
C.700
D.CAN'T BE DETERMINED

The answer is Can't be determined...But i would like to know how....i request anyone to explain the term rebate in a clear view

Reply Like? Yes | No

(10 years ago)

Let the List Price(Marked Price) = x Rs.
After 10% Rebate on List Price the S.P(Selling Price) of that Product will be 90% of M.P
i.e 90*x/100 Rs.

or S.p = 90x/100 Rs.
According to the question It is given that Profit is 70 Rs.

And we know that , S.P - C.P = Profit
9x/100 - C.P = 70..............( 1 )

The above equation is in variable "x" and also we have to find out the value of C.P , which is impossible.

That's why only D.Option is correct

(A+B) 1 hr"s work=(1/12+1/15)=3/20
(A+c)1 hr"s work=(1/12+1/20)=2/15
part filled in 2hr"s=(3/20+2/15)=17/60
for 6hr's=6*(17/60)/2=17/20
remaining=(1-17/20)=3/20
so now it's a turn for A+B and we know that (A+B) 1hr's work is (3/20)
so add 6+1=7hrs given option is wrong i think so

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
