if one apple get 25% profit and another apple gets 25% loss then what is the change ..either loss or profit ?

Reply Like? Yes | No

Devendra Marghade 9 years ago

No profit, No loss

Considering the cost prices of each the apples=x, then total cost price=2x
Selling one at 25% profit & another at 25% loss will give total selling price=(125/100)x + (75/100)x=2x
As selling price=cost price, So there is no profit and no loss.

no loss no gain
if the apple cost is 100 each
1st one selling price is 125
and 2nd is 75..
Total gives 200 which is cost price of 2 apples..
so no loss no gain

Rajul Singh Gaur 9 years ago

Speed = 54 x 5 m/sec = 15 m/sec.
18
Length of the train = (15 x 20)m = 300 m.

Let the length of the platform be x metres.

Then, x + 300 = 15
36
x + 300 = 540

x = 240 m.

A company rented a machine for Rs.700/- a month. Five years later the treasurer calculated that if the company had purchased the machine and paid Rs.100/- monthly maintenance charge, the company would have saved
Rs.2000/-. What was the purchase price of the machine?

Reply Like? Yes (4) | No (4)

Rajul Singh Gaur 9 years ago

Let the price of the machine = x rupee
5 year maintenance charge = 100*60 = 6000
so total investment = x+6000
now total rental charges for five year = 700*60 = 42000
so according to given condition 42000-x-6000 = 2000 so x = 34000

Q: Viru and dhoni are running in a race if there speed is in the ratio 5:3 respectively and total distance traveled by them in one round is .5 km . Find the distance traveled by viru when he passes dhoni for the sixth time.
PLEASE SOLVE THIS QUES.... I HAVE WASTED LOTS OF TIME TO SOLVE THIS.

Reply Like? Yes | No

Rajul Singh Gaur 9 years ago

let speed of viru and dhoni are 5x and 3x.
ratio of distance traveled by them= ratio of speed of them =5:3
total distance traveled by both=.5km
so distance traveled by viru in one round= .5*(5/8) =.3125km and distance traveled by dhoni in one round will be .1875 km.
so the length of track =.3125.
time taken by viru to complete one round=.3125/5x
and time taken by dhoni to complete one round=.3125/3x
both will meet after time( LCM of .3125/5x and .3125/3x)=.3125/x
both meet for the sixth time after (.3125/x)*6
so distance traveled bu viru upto 6th meet = (.3125/x)*6*5x =9.375km

Like? Yes (1) | No

siddharth prakash singh 9 years ago

Ans will be 7.5 km.
Let the speed of viru and dhoni be 5x and 3x respectively.
( Since we know that if two or more person starts moving from same pt on the circumference of circle on the same path in the same direction around the circle they will first meet in the lcm of time the fastest runner takes in totally overlapping each other.)
so to find overlapping time we have to find relative speed of both person (as here only two persons are given)
so their relative speed is 2x.
let they will meet after t sec.
so, 2xt=0.5
t=0.25/x
hence viru will overlap dhoni at every 0.25/x unit time.
now distance traveled upto first meeting by viru= 5x*t =1.25 km .
hence viru will cover 1.25*6= 7.5 km when he will cross dhoni 6th time.

the first statement of the ques is v confusing so ignore it
lets begin with the subsequent part of the ques

Like? Yes | No

neha 9 years ago

so.. lets begin
since for 5 strikes time taken is 6 sec and time taken to strike once is negligible
so no. of strikes=5-1=4
so time taken to strike 4 times=6 s
so strike per times=4/6= 1.5 s
similarly, for 9 stirkes time taken =12 s
so time taken per strike= 12/8=1.5 s
so wen it strikes once it takes negligible time.
wen it strikes twice it takes 1.5 s,
wen it strikes thrice it takes 1.5+1,5 s,
wen it strikes 4 times it takes 1.5+1.5+1.5 s
so it forms an AP
so for one rotation i.e. from 12 to 12 i.e. it completes 12 hr strikes
time taken=
@1 @2 @3 @4 ..... @12 back at 1
1.5*0+1.5*1+1.5*2+1.5*3......1.5*11+1.5*0
=>1.5(1+2+..+11)
sum of n terms of an ap=n(n+1)/2
1.5(11*12)/2= 99 secs
so time taken to strike 24 hours =99*2=198 secs. ans

actually the rays wil enter from theh corner and reach d bottom at 2.5 cm (the centre of the bottom)
the rays wil be slant and fall at an angle of 45 degree
since angle of incidence is same as angle of reflection it wil reflect in d same mannern exit from top right corner.
so two right angles are formed
2.5^2+15^2=hypotenuse^2
so total distance =2*(sq root(2.5^2+15^2)) ans.

Ashwini Nandan 5 years ago

For n bits, the range of 2’s complement signed integers that are allowed is -2^(n-1) to (2^(n-1))-1.

For your question, you asked the range of 6 bit signed integers, I am assuming you are asking for the range in 2′C format. The answer is -32 to +31 both numbers included. Hence, 32 and 64 both cannot be represented by using 6 bits.

Like? Yes (1) | No

Pritam 4 years ago

2^6 = 64. So you can represent 64 values. This means 0 to 63 for unsigned integer and -32 to 31 for signed integer (twos complement).
