You can assume through the option that if you add 4 in both 12 and 44 than we get 16 and 48 which satisfied the condition

Like? Yes | No

option a 12 n 44

Like? Yes (1) | No

(11 years ago)

ans :a) 12 yrs, 44 yrs
father's age=x
son's age=y
x+y=56 ->equation 1
after 4 years (x+4)=3(y+4) ->equation 2
from equation 1 we will get y=56-x
substitute y value in equation 2
x+4=3((56-x)+4)
x+4=168-3x+12
x+3x=180-4
4x=176
x=176/4
x=44 -> Father's age
then substitute y value to equation 1
44+y=56
so we get y=56-44
son's age y=12

305 in base 2 has 9 digits.....so he can divide the number in half going from 305 to 1(i.e. Deepak Sharma) = 9*2 = 18

Like? Yes | No

(11 years ago)

305/2 => 152 => 76 => 38 => 19 => 9 => 4 => 2 => 0 Up on Successive division by 2 for 305 entries, we end up in 0 after 9 intervals. and each takes 2 mins to answer hence 9*2=18

It is actually based on Binary search. Since, the numbers are in alphabetical order of names, she can call the last number and ask his name. Based on the response, she picks up 305/2 = 152 nd number. Then, 152/2 = 76 th number, then 76/2 = 38th number, 38/2 = 19 th number, 19/2 = 9th number, 9/2 = 4th number, 4/2 = 2nd number, 2/2 = 1st number. So, she has to make minimum 9 calls. Each call duration is 2 minutes. So, she takes 18 minutes.
