151. There are 60 slots around a circle, numbered 1 to 60. A man starts from the first slot and jumps to the 5th slot. From there he jumps to the 9th slot and so on. In which slot will he land in his 2200th jump?

**Answer:**** Option B **

**Explanation:**

At each jump it moves 4 slot.

So, total jump * 4 will give at which slot he is i.e. 2200 * 4 = 8800

but given that. there are 60 slots around a circle

so take mod 60

8800 mod 60 = 40

but mod gives and between 0 to 59...but actual slot number are from 1 to 60 hence +1 ans

hence final answer is 40 +1 = 41

154. Three non negative numbers, X, Y and Z are such that the mean is M and the median is 5. If M is 10 more than the smallest number and 15 less than the biggest number, find the value of X+Y+Z.

**Answer:**** Option D **

**Explanation:**

Given median=5,so y=5

x+y+z/3=10+z ---(1)

x+y+z/3=x-15 ---- (2)

By solving eq. (1) and (2) we get,

x=25,y=5,z=0

so x+y+z=30

F+6=2(R+6)

F= 2R+6

M-2=2(R-2)

M= 2R-2

Therefore the sum of Raju's Parent's age is

F+M=2R+6+2R-2

F+M=4R+4

4 more than four times Raju's age

**Answer:**** Option C **

**Explanation:**

At 12 o clock A cover 40km and on the other side B at 11 o clock cover 40km, again they traveled towards each other(which is actually the distance between them), that is A has to traveled 2hr(From 12 to 2 at 20km/hr) i.e 2*20=40km and other side B has to traveled 3hr(From 11 to 2 at 40km/hr) i.e 3*40=120Km.

Then the total distance traveled by them is the Actual distance between them ie 40+120=160Km(Ans.)

159. A circle has 29 points arranged in a clockwise manner numbered from 0 to 28. A bug moves clockwise around the circle according to the following rule. If it is at a point i on the circle, it moves clockwise in 1 second by ( 1 + r ) places, where r is the reminder ( possibly 0 ) when i is divided by 11. Thus if it is at position 5, it moves clockwise in one second by ( 1 + 5 ) places to point 11. Similarly if it is at position 28 it moves ( 1 + 6 ) or 7 places to point 6 in one second.

If it starts at point 28, at what point will it be after 9994 seconds?
