181+6^{3}+7 = 404

404+7^{3}+8=755

755 +8^{3}+9=1276

20+2+0= 22

22+2+2 = 26

24 + (6*1) = 30

30 + (6*3) = 48

48 + (6*5) = 78

78 + (6*7) = 120

120 + (6*9) = 174 - 71, 96, 145, 226, 347, ?

71, 96, 145, 226, 347, ?

71+ (5)^{2}= 96

96+ (7)^{2}= 145

145+(9)^{2}= 226

226+(11)^{2}= 347

347+(13)^{2}= 516 - A fisherman bought a new motorboat which could travel in still water at 20 km/hr. He has to move to an island 3182km away and come back. How much time will it take for the entire journey if the speed of the stream is 1.5 km/hr?
320 hrs.300 hrs.288 hrs.150 hrs.344 hrs.Option A

Speed of downstream = (20+1.5)= 21.5km/hr.

Speed of upstream = (20-1.5) = 18.5 km/hr.

Total time taken = 3182/21.5 + 3182/18.5

= 148 + 172 = 320 hours - A water tank is filled in 3 hours by 3 pipes X,Y and Z working together. The pipe X is 3 times as fast as pipe Y and pipe Y is 4 times as fast as pipe Z. Then in how much time will pipe Z take to fill the tank alone ?
36 hrs.45 hrs.20 hrs.51 hrs.60 hrs.Option D

Let pipe Z takes x hours to fill the tank alone, pipe Y will take (x/4) hours and pipe Z will take (x/12) hours . Together they filled the tank in 3 hours .

Now, 1/x + 4/x + 12/x = 1/3

=> x = 51 hours - P and Q start a business by investing Rs.700 and Rs.600 respectively. After three months P withdraw (2/7) of his investment but further three months he reinvested (3/5) of withdraw. If they receive Rs. 726 as a profit after end of the year then find the share of P?
Rs.250Rs.300Rs.366Rs.422Rs.316Option C

Ratio of the investments

= (700 *3 + 500 *3 + 620*6) : (600*12)

= 183 : 180

Pâ€™s share = Rs.366 - A goods train engine speed is 56km/hr. without any wagon attached. If the reduction in the speed of engine is directly propotional to the square root of the number of attached wagons , when there are 16 wagons attached then speed calculated 24 km/hr. Find the maximum number of wagons train can carry ?
4537404856Option D

56 â€“ 24 = k(16)^1/2

=> 32 = k*4

=> k = 8

Now, 56 â€“ 0 = 8(w)^1/2

=> w = 49

For moving train = 49-1 = 48 - There are two fathers i.e Mohan and Mohit and two sons i.e Mohit and Mannu in a family. Ratio between grandfather and grandson is 3:1 . Mohit is 26 years older than Mannu and average age of all three is 50(1/3) . What is the difference between the age of Mohan and Mohit ?
15 years24 years35 years40 years18 yearsOption B

Mohan = 3x

Mohit = x+26

Mannu = x

sum of their ages = 3x+x+26+x = 151

=> x = 25

Required difference = [(3*25) â€“ (25+26)] = 24 years
