Zuti engineering solutions Interview Questions, Process, and Tips

4x:5x:6x
100:50:25
100×4x +50×5x+25×6x
then 400x + 250x + 150x = 16000
800x=16000
x = 20

25 paisa=6x = 20×6=120

so the ans is 120 coins

Hockey

B.25

(115+65+x)/3=95
x=105

Yes, technology give me better efficiency to my work. Just we have take a work piece of sheet metal to convert in product like is box, different size, where manually it’s complete on 3 to 4 days but with the help of technology I have done in 3 hours that’s I said the technology give better efficiency to my better work.

A=P+SI——(1)
sum of money after 30 years = Double the money
A=2P———-(2)

Equate 1 and 2
P+SI=2P
SI=2P-P
SI=P————-(3)

WKT, SI= PTR/100

Equate 3 and SI

P=PTR/100
P=P*30*R/100
R=P*100/P*30
R=100/30 or 10/3 or 3(1/3) %

C. 8 kg

Time =9 seconds

Speed =(60×518) m/sec=(503)m/sec

∴ Speed =DistanceTime

Length of the train (Distance) = (Speed × Time) = (503×9) m=150 m.

volume of a sphere is 4/3 * pi * r^3
by drilling a hole 6 inches long the volume of the sphere is
not affected bcos the hole is a 1 dimension quantity..(say a
straight line) n so it does not have any value w.r.t volume…
hence the volume of the sphere does not change..

13 and 15

A. Rs 140
7+8+11=26
B: 7/26*520= 140

B

let x be lenghth of candles.

thicker one—- in 1 hr 1/6th will go.
thinner one— in 1 hr 1/4th will go.

let he lit for n hrs.

so in n hrs thicker one goes n/6.
and thinner one goes n/4.

so remainini length are x-n/6 and x-n/4.so x-n/6=2(x-n/4)
implie n=3x. if x=1 n=3hrs.
