Answer / jhilam bera
At 1:00 pm the dif'n between A & B = 8 km
after 2:00 pm ................... = 11 km (as B's speed
is 1 and A's 4km, then eqv speed=(4-1)=3km)
After 3:00....................... = 13km (as B's speed 2km)
After 4:00....................... = 14km
after 5:00....................... = 14km (A's speed= B's
speed)
after 6:00....................... = 13km
after 7:00....................... = 11km
after 8:00....................... = 8km
after 9:00....................... = 4km
and now the eqv speed is= (9-4) =5km/hr;
and the remaning distance is 4km;
then, time=(60*4)/5=48 min;
then the meeting time is=9:00+48min=9:48 pm;

Answer / vivek kumar 2k6 bit mesra
lets say it takes time = T hr + t(fraction)hour
then for for T hours distance traveled by A = 4(T+2)
and that by B = T(T+1)/2
also Dist travelled by A > dist by B .......in T hours as in T+t hours it B reaches to A
4(T+2)>T(T+1)/2
-1.815 < T < +8.815
so integral value of T= 8 hours
So in 8 hr A travelled 4(8+2)=40
B travelled 8(8+1)/2=36
so this lag in distances will be covered up in t minutes
now speed of B will be 9 in the 9th hour
so, 9t-4t=4
t=4/5hr
=48 minutes
So the total time taken is T + t
= 8hr + 48 min
So answer will be 1pm+8:48 = 9:48pm............Ans

Answer / satish raj
A covers 8km till 01.00:pm and B starts at 01.00pm.hence at this point distance among them is 8km.
hence after 1hour at 02.00pm distance among them will be
11 km(i.e with a relative speed of 4-1=3km/h A will cover increase 3km gap).
At 03.00 pm,distance among them will be 13km(i.e. with a relative speed 4-2=2km/h and hence increase 2km gap)
hence,At 04.00- distance among them will be 14km.
at 05.00-distance among them will be 14km.
now 05:00pm-06:00pm slot relative speed will be countable and going with it- we will get 13hr-11hr-8hr-4hr and this 4 gap of will be completed in 4/5 hour=48min(because at that slot relative speed of B will be 5km/h).
ans:-09.48:pm

Answer / vikram mandal
A goes by (11am-1pm)2h 8km.
A covers 3hours=B covers 1hour.
so,A covers the distance of 10hours=40km
where B covers the distance of 8hours=36km
now,speed of B's is 9km/h.
where speed of A's is 4km/h.
within next 1hour A will cover 44km.
so,(44-36)km=8km.to cover this distance B needs time=(8/9)h=.88h
So,B catch up to A same day to 08.54p.m.

Answer / avinash
They will meet after 1 pm.A has unique speed 4 km/hr.so,A cross 8 km at 1 pm.But,B increase speed like(1+2+3+4+5+6+7+8+9 = 45).For A 9*4=36 + 8=44. so before 9 pm and after 8:30 pm they should meet.So, Answer is : 8:45 PM.

10) On planet korba, a solar blast has melted the ice caps on its equator. 9 years after the ice melts, tiny planetoids called echina start growing on the rocks. Echina grows in the form of circle, and the relationship between the diameter of this circle and the age of echina is given by the formula d = 4*√ (t-9) for t ≥ 9 Where d represents the diameter in mm and t the number of years since the solar blast. Jagan recorded the radius of some echina at a particular spot as 7mm. How many years back did the solar blast occur? a) 17 b) 21.25 c) 12.25 d) 12.06 Ans: b
