a) 35/256
b) 33/220
c) 63/253
d) 43/190
e) 59/253


Q1. SOL:   D

More the diameter more will be the water flowing through it and less will be the time taken.
Means bigger pipe will take less time to fill the tank
So, for 1 cm time, (1^2)/(3^2) = 21/t, we get t = 189
For 2 cm time, (2^2)/(3^2) = 21/t. We get t = 189/4
So total time = 1/21 + 1/189 + 4/189 = 2/27
So total time = 13.5 minutes

Q2. SOL:   D

The tank supposed to be filled in (30*20)/50 = 12 minutes
so, (1/20 + 1/30)*12 – 12/C + (1/20 + 1/30)*5 = 1 (A and B work for 12 minutes and also C work for 12 minutes and then A and B takes 5 more minutes to fill the tank)
solve for C, we will get C = 144/5 = 28.8

Q3.  SOL:   D

Time taken by a deer to complete one round = 9 minutes
Time taken by a rabbit to complete one round = 5 minutes
They meet together for the first time at the starting point = LCM of 9 and 5 = 45 minutes.

Q4. SOL:   D

Side of 1st square = 60/4 = 15 cm.
Smallest side of right angled triangle= 15 −6 = 9 cm.
Length of 2nd rectangle = 80/5 = 16 cm.
Second largest side of the 1strectangle = 16−4 = 12 cm.
Largest side = hypotenuse=√9^2+12^2=15cm

Q5. SOL:   C

Volume of the ball = volume of the raised water
4*22*r3/3*7 = 22*100*5
r= 11000*3*7/88 = 2625
r = 13.79 or 14

Q6. SOL:   B

D = 40(t+20/60) and D = 60(t-10/60)
solve these two equation and get D.

Q7. SOL:   A

26000*12 : 16000*9 : 25000*6
312:144:150 = 156 : 72 : 75
K’s share = 17000* 75/303 = 4208
9-6 = 3

Q8. SOL:   B

SI =>Amount = x*8*7/100 + x = 56x+100x/100 = 156x/100 = 39x/25
CI=> 39x/25[(1+10/100)2 – 1] 1638 = 39x/25[121/100 – 1] = 39x/100[21/100] X = 1638*100*25/21*39 = 5000

Q.9 SOL:   C


Q10. SOL:   C

From 1 to 24, there are 8 numbers which are multiple of 3
Case 1: 2 are multiple of 3, and one any other number from (24-8) = 16 tickets
8C2*16C1 / 24C3 = 56/253
Case 2: all are multiples of 3.
8C3 / 24C3 = 7/253
Add both cases.
