- 14, 13, 22, 55, 212, 1035
1035212225514Option D

14, 13, 22, 55, 212, 1035

14 × 1 – 1 = 13

13 × 2 – 4 = 22

22 × 3 – 9 = 57

57 × 4 – 16 = 212

212 × 5 – 25 = 1035

Hence, the wrong number is 55. - 217, 224, 213, 226, 210, 228
210228224226213Option A

217, 224, 213, 226, 210, 228

217 + 7 = 224

224 – 11 = 213

213 + 13 = 226

226 – 17 = 209

209 + 19 = 228

Hence, the wrong number is 210. - 153, 495, 712, 837, 901, 928
712153901495928Option D

153, 495, 712, 837, 901, 928

153 + 7^3 = 496

496 + 6^3 = 712

712 + 5^3 = 837

837 + 4^3 = 901

901 + 3^3 = 928

Hence, the wrong number is 495. - 11, 42, 214, 1045, 4148, 12417
1112417214414842Option C

11, 42, 214, 1045, 4148, 12417

11 × 7 – 7 × 5 = 42

42 × 6 – 6 × 6 = 216

216 × 5 – 5 × 7 = 1045

1045 × 4 – 4 × 8 = 4148

4148 × 3 – 3 × 9 = 12417

Hence, the wrong number is 214. - 488, 245, 124, 64, 35, 20.25
6424512448835Option E

488, 245, 124, 64, 35, 20.25

488 ÷ 2 + 1.0 = 245

245 ÷ 2 + 1.5 = 124

124 ÷ 2 + 2.0 = 64

64 ÷ 2 + 2.5 = 34.5

34.5 ÷ 2 + 3.0 = 20.25

Hence, the wrong number is 35. - A horse and a carriage together cost Rs 8000. If by selling the horse at a profit of 10% and the carriage at a loss of 10% a total profit of 2.5% is made, then what is the cost price of the horse ?
Rs. 4000Rs. 9000Rs. 7000Rs. 5000Rs. 6000Option D

Let the CP of horse be Rs x.

then CP of carriage would be Rs (8000 -x)

SP of horse = 1.1x SP of carriage = 0.9 (8000 – x)

=>1.1x × 0.9 (8000 – x)= 8000 × 1.025

=>1.1x + 7200 – 0.9x = 8200

=> 0.2x = 1000

=> x = Rs. 5000 - A well with 14 m inside diameter is dug 10 m deep. Earth taken out of it has been evenly spread all around it to a width of 21 m to form an embankment. Find the height (in metres) of the embankment.
1/2 m5/7 m2/3 m6/7 m3/5 mOption C

Volume of earth dug out = (22/7 * 7 * 7 * 10)

= 1540 m^3

Area of embankment = 22/7 [(28)^2 – (7)^2] = 2310 m^2

Height of embankment = Volume/Area

= 1540/2310 m

= 2/3 m - A train can travel 20% faster than a car. Both start from the point A at the same time and reach point B, 75 km away from A at the same time. On the way however the train lost about 12.5 min while stopping at the stations. Find the speed of the car.
60 km/h20 km/h30 km/h40 km/h50 km/hOption A

Let the speed of the car be x km/h.

Speed of train = x × 1.2

= 6x/5 km/h

Now, (5/6x) * 75 + 25/ (2*60) = 75/x

= 60 km/h - 9 children can complete a piece of work in 360 days. 18 men can complete the same piece of work in 72 days and 12 women can complete the piece of work in 162 days. In how many days can 4 men, 12 women and 10 children together complete the piece of work ?
63 days77 days62 days50 days81 daysOption E

9 × 360 children = 18 × 72 men = 12 × 162 women 45 children =18 men = 27 women

5 children = 2 men = 3 women

Now, 4 men +12 women +10 children

= 4 men + 8 men + 4 men

= 16 men 18 men can complete the work in 72 days.

16 men can complete the work in = (18 * 72)/16

= 81 days - A video magazine distributor made 3500 copies of the March issue of the magazine at a cost of Rs 350000. He gave 500 cassettes free to some key video libraries. He also allowed a 25% discount on the market price of the cassette and gave one extra cassette free with every 29 cassettes bought at a time. In this manner, he was able to sell all the 3500 cassettes that were produced. If the market price of a cassette was Rs.150, then what is his gain or loss per cent for the March issue of video magazine ?
8.18%6.78%4.15%5.42%7.25%Option B

CP of 3500 cassettes = Rs 350000

The SP of one cassette after discount is Rs =112.50

SP of each set of 30 cassettes = (29 +1) = Rs 29 × 112.50

= Rs 3262.50

SP of 3500 cassettes including 500 free cassettes = Rs 326250

Overall loss on Rs 350000 is Rs 23750

Loss percent = (23750/350000) × 100

= 6.78%
