MBA Exam Numerical Ability Number System

A number is represented in the number system to the base 8 by three hundred consecutive 3s. What is the representation of N in the number system to the base 4?

1) 3333….upto 450 terms
2) 1231123111223…..upto 450 terms
3) 123123….upto 300 terms
4) 121212…..upto 450 terms
5) None of these

Read Solution (Total 1)

(333333.......300th )base8---->(..........)base4

No. of terms would increase as base is decreasing so option 3 eliminated
also when converted into base 4 no. of terms would be 450 and
4--->2^2 so pattern cums like dis
(011011011......011011011)base4 taken 2 digits frm rightt at a time--->
(123123123.....123123)base4 no. of digits=450
none of these option

Suppose, the seed of any positive integer n is defined as follows:
seed(n) = n, if n < 10
= seed(s(n)), otherwise,
where s(n) indicates the sum of digits of n. For example,
seed(7) = 7, seed(248) = seed(2 + 4 + 8) = seed(14) = seed(1 + 4) = seed(5) = 5 etc. How many
positive integers n, such that n < 500, will have seed (n) = 9?
