TCS Company Numerical Ability Age Problem

3 years ago Jacob's age was twice John's age. 3 years hence Jacob's age will be 4/3 times the age of John's. Find Jacob's present age in binary numbers.

Read Solution (Total 2)

let present age of jacob is X year;
and present age of john is Y year;
now 1st statement says: (X-3)=2(Y-3);
and 2nd statement says: (X+3)=4/3(Y+3);
hence solving these equations we get: X=9 and Y=6;
and hence jacobs age will be in binary: 1001.

let jacobs age be x..n johns age b y(present ages)
3 yrs earlier..(x-3)=2(y-3)
3 yrs later..(x+3)=4/3(y+3)
solving u vl get..x=12&y=6

convert x into binary num..u vl get d answer

Now consider 6 people standing in a que of a super market. You want to predict where behavior based on their age group. You get to know from the super market record that there average age 2 years ago was 41 years. After a while another person joins the queue and the present average age of all the 7 is 39 years. The present age of the last person in queue is.
