x+y+z=0 ; x >= 5 ; y >= -5 ; z >= -5 . how many integral solutions ??

Reply Like? Yes (2) | No

As per given conditions assume x=m+5 , y=n-5 , z=o-5 , where m,n,o>=0
so now equation becomes m+n+p=5
values satisfy (1,1,3) => 3 integral solution [i.e. (1,1,3),(1,3,1),(3,1,1)]
(1,2,2)=> 3 integral solution
(4,1,0)=> 3 integral solution
(3,2,0)=> 3 integral solution
so total 12 integral sol

Recently I completed my return test for IBM for the job role of “Associate System Engineer” which was conducted at MLRIT at Hyderabad.
I got a mail that they will invite me for final round interview as soon as possible. But today I got another mail from IBM that
We are reaching out to you for an immediate requirement for an “Associate – Technical Operations” role for our GTS Infrastructure Service Delivery Business Unit.
Having assessed your candidature recently for the “Associate Systems Engineer” role we believe that you would make a good fit for our new requirement.

10000 Rs.

If initial cost price=x, selling price @20% profit=(120/100)*x=1.2x
New selling price with Rs. 500 more=1.2x+500
With new selling price profit is 25%, so 1.2x+500= (125/100)*x, x=10000

Q: A sum becomes 6 fold at 5 % per annum. At what rate the sum becomes 12 fold ?

a) 9 % b) 10 c) 11 d) 12

Reply Like? Yes (13) | No (1)

(9 years ago)

c) 11

For the sum to become 6 fold, its interest should be 5 times the sum. So if sum=x & period=t, then
Calculating simple interest, x *t*5/100 = 5x, t=100
Now for the sum to become 12 fold for t=100 & rate=r,
x*100*r/100=11x, r=11

volume of cylinder=pie*(r^2)*h
here in this case ot will be=pie*((outer radius^2)-(inner radius^2))*h
inner radius=70-4=66cm
=> ((outer radius^2)-(inner radius^2))=70^2-66^2=544
pie*h*544=22*63*544/7=107712 cm^2 ans.

as we know compound interest is the interest on the interest
so rate of interest=100*56.25/375%=15%
so by the formula PRT/100=375
put R=15%, T=1, find p
P*15*1/100=375
P=375*100/15

Lalita gave 25 gold coins to her husband, Amita donated 15 gold coins and Neeta made jewellery out of 30 gold coins. The new respective ratio of the coins left with them was 20 : 73 : 83. How many gold coins did Amita receive from Mr. Pandit?

Reply Like? Yes (20) | No (9)

380 gold coins

No. of total gold coins left = 950-(25+15+30)=880
total ratio = 880/176 = 5
so Amita ratio = 73 ie., 73*5 =365
Amita have donated 15 coins.. so she got 380 from his father Pandit
