Three companies are working independently and receiving the savings 20%, 30%, 40%. If the companies work combinely, what will be their net savings?
suppose total income is 100
so amount x is getting is 80
y is 70
but total money is 300
so they are getting 90 rs less
90 is 30% of 300 so they r getting 30% discount
The income ratio of C and D is 3:4.the ratio of their expenditures is 4:5. Find the ratio of their savings if the savings of C is one fourths of his income?
If P(0) = -1 P(1)= 1 and P(N)=P(N-1) - P(N-2) then what is the value of P(6)?
Person1 can copy 40 pages in 10 hours .Person1 and Person2 together can copy 60 pages in 10 hours, how much time does Person2 takes to copy 26 pages?
Person1 can copy 4 pages in 1hr.(40/10)
Person1 and person2 can copy 60 pages in 10hrs.
thus, Person2 can copy 80 pages in 10 hrs.[eqn. is (40+x)/2=60, where x--> no. of pages Person2 can copy in 10 hrs.]
so, Person2 can copy 9 pages in 1hr.So to copy 26 pages Person 2 will need almost 3hrs.
One circular array is given(means memory allocation takes place in circular fashion) diamension(9X7) and starting add. is 3000, What is the address of (2,3)........
it's a 9x7 int array so it reqiure a 126 bytes for storing.b'ze integer value need 2 byes of memory allocation. and starting add is 3000
so starting add of 2x3 will be 3012.
In a car racing a car started at 8.00a m and after 30 min staying at destination, It returned back to the starting place. The destination is 27 miles from the starting point. the speed of the car 50 percent fast speed. at what time it returns to the starting point
A car cover 27 mile with 18 mph in =27/18= 1 hour 30 min. and it wait at starting point =30 min.
after this speed of return increase by 50% so 50%of 18 mph=9mph
Total speed of returnig=18+9=27
Then in return it take 27/27=1 hour
then total time in joureny=1+1:30+00:30 =3 hour
so it will come at 8+3 hour=11 a.m.
In a town Low temperature at the night is 1/3 more than 1/2 high as higher temperature in a day. Sum of the low temperature and highest temp.is 100 degrees. Then what is the low temp?
Let highest temp be x
so low temp=1/3 of x of 1/2 of x plus x/2 i.e. x/6+x/2
Lowest temp is 40
In Vizag, temperature at noon varies according to v2/2 + 8v + 3, where t is elapsed time. Find how much temperature more or less in 4pm to 9pm
In Equation first put t=9,
we will get 34.5
now put v=4,
we will get 27
A person had to multiply two numbers. Instead of multiplying by 35, he multiplied by 53 and the product went up by 540. What was the raised product?
x*53-x*35=540=> x=30 therefore, 53*30=1590 Ans
How many positive integer solutions does the equation 2x+3y = 100 have?
Given 2x+3y=100, take l.c.m of 'x' coeff and 'y' coeff i.e. l.c.m of 2,3 ==6then divide 100 with 6 , which turns out 16 hence answer is
The total expense of a boarding house are partly fixed and partly variable with the number of boarders. The charge is Rs.70 per head when there are 25 boarders and Rs.60 when there are 50 boarders. Find the charge per head when there are 100 boarders.
Let a = fixed cost and k = variable cost and n = number of boarders
total cost when 25 boarders c = 25*70 = 1750 i.e. 1750 = a + 25k
total cost when 50 boarders c = 50*60 = 3000 i.e. 3000 = a + 50k
solving above 2 eqns, 3000-1750 = 25k i.e. 1250 = 25k i.e. k = 50
therefore, substituting this value of k in either of above 2 eqns we get
a = 500 (a = 3000-50*50 = 500 or a = 1750 - 25*50 = 500)
so total cost when 100 boarders = c = a + 100k = 500 + 100*50 = 5500
so cost per head = 5500/100 = 55
Kiran bought 5 pens, 7 pencils and 4 erasers. Raju bought 6 pens, 8 erasers and 14 pencils for an amount which was half more than what kiran had paid. What % of the total amount paid by Kiran was paid for pens?
Let, 5 pens + 7 pencils + 4 erasers = x rupees
so 10 pens + 14 pencils + 8 erasers = 2*x rupees
also mentioned, 6 pens + 14 pencils + 8 erarsers = 1.5*x rupees
so (10-6) = 4 pens = (2-1.5)x rupees
so 4 pens = 0.5x rupees => 8 pens = x rupees
so 5 pens = 5x/8 rupees = 5/8 of total (note x rupees is total amt paid byamal)
i.e 5/8 = 500/8% = 62.5% is the answer
I lost Rs.68 in two bets. My second bet loss is Rs.6 more than the first bet. My friend lost Rs.4 more than me in the second bet. What is the amount lost by my friend in the second bet in Rs.?
x + x+6 = rs 68
2x + 6 = 68
2x = 68-6
2x = 62
x is the amount lost in I bet
x+ 6 = 31+6=37 is lost in second bet
then my friend lost 37 + 4 = 41 Rs
Sumo is filled with four and half gallons of oil for full round trip. Fuel is taken 1/4 gallons more in going than coming. What is the fuel consumed in coming up.
let fuel consumed in coming up is x. thus equation is: x+1.25x=4.5ans:2gallons
In a software company work is done by the Employees in 24 min. One of them can do this work alone in 40 min. How much time required to do the same work for the second person
Two people work together in 24 mins.
So, their one day work is
One man can complete the work in 40mins
one man's one day work (1/B)= (1/40)
So, A can complete the work in 60 mins.
In a company 30% are supervisors and 40% employees are male if 60% of supervisors are male. What is the probability? That a randomly chosen employee is a male or female?
40% employees are male if 60% of supervisors are male so for 100% is 26.4%so the probability is 0.264
