Two brothers were expected to return here on the same day. Hardik returned 3 days earlier but Kunal returned 5 days later. If Hardik returned on Tuesday, what was the expected day when both the brothers were to return home and when did Kunal Return?

Hardik returned on Tuesday -i.e. 3 days earlier
so actual day to return home is Friday.
Kunal returned after 5 days so Wednesday
S1:S2=1:(3/4)
Since speed and time are inversely proportional. So t1:t2=3/4:1=3:4
Now,diff in time is 1.5 hrs. So,
4x-3x=1.5
X=1.5
So usual time is 3x = 4.5 hours

Divisible by 9 are 9,18,27,36,45,54,63,72,81,90,99,108,117,126,135, 144, 153
Divisible by 4 are 36,72,108 and 144
So, divisible by 9 but not by 4 = 17-4 = 13
