Open University of Hong Kong Interview Questions, Process, and Tips

c=a/b
c=a-1
=>b=a/c
=>b=a/a-1

Its very simple..
consider the fraction of s in the mixture = 1/3
So if we add one more R the the fraction wil be = 1/4
Automaticaly S becomes 25% of the mixture

80

If the bell rung when they r started is also counted then it
will be 5 otherwise 4

avg sal of 3 is $950
first person earns=$1150
second person earns=$650
let thirdperson =x
avg=(1150+650+x)/3
950*3=1800+x
x=2850-1800
x=$1050

3

let no of total crockery =x
2x/3 crockery broken
x/2 handle broken
x/4 both brocken
2x/3+x/2-x/4 = no of total broken(crockery or handle)
=11x/12
unbroken =x-11x/12=x/12
x/12=2(given in question)
x=24

T is the last speaker.

1, 2, 4, 13, 31, 112,?
This series is written in base 5 numbers for decimal nos of 1,2,4,8,16,32,64

so next number is 224 .
224 in base 5 = 64 in base 10.

so 224 is next number.
