Yuan ze university Interview Questions, Process, and Tips

these are question tht are seem to be like it consumes
time. so dont see jus the question and run to the next .

ans. a) 12

if 9 balls are added then the ratio to the combination
becomes 2:4:3.

9 balls make the ratio 3 for grey balls in tht mixture.
so the factor is 9/3 = 3 (in tht mixture)

so the same factor has to be maintained through out the
ratio. so black balls is 4 * 3 = 12 and white balls is 2 *
3 = 6.

4 boy 3 sis

answer : 36 –Explaination:
X= Chickens
Y = Qty per day

X*Y*9= 12 *.9 *Y*30

x=36

By 1hour both trains meet, so the distance travel by fly in
1hr is 120km.

No, the tank will be filled after 36 minutes

24/16= 1,5

24×1,5= 36

Let x be fathers present age and y be son present age.
5 yrs ago, the age of father and son be x-5 & y-5.
Then,
x-5+y-5=40
x+y-10=40
x+y=50
y=50-x ———–> (1)
ratio between father and son in present age
x:y=4:1
x/y=4/1
x=4y
Apply eq (1) ,
x=4(50-x)
x=200-4x
x+4x=200
5x=200
x=200/5
x=40,,
=> The present age of father is 40.

3×3=9

343 : 729 :: 125 : ?
7^3 : 9^3 :: 5^3:7^3

Answer:50.24
Explanation:
Area of a circle =π*r*r
616=π*r*r
r*r= 616÷3.14
r*r =196
r =13
Circumference of a circle= 2*π*r
=2*π*13
=16*3.14=50.24
