TCS Other Question

In a group of 120 people 90 have an age of more 30yrs and the other have age of less then 20 yr.if a person is selected at random from htis group .what is the probability the person's age is less than 20.

0.25
0.33
0.42
0.52 32^32^32/7 what is the remainder?

4^32^32/7 as 32%7=4
now, 4^3/7 gives us remainder 1;
we have to write 32^32 in the form of 4^3n+x where x is the unit digit of 32^32 ie 6
so,
we can re write the problem as
4^3n+6/7
=>4^3n/7 always gives remainder 1
and 4^6/7 gives remainder 1.
so final remainder should be 1...what is wrong in it ? as the ans given is 4.
