132218118Option C

15 + 3 = 18

18 – 2 = 16

16 + 3 = 19

19 – 2 = 17

17 + 3 = 20

20 – 2 = 18 - 10, 14, 25, 55, 140,?
316388302350374Option B

14 – 10 = 4

25 – 14 = 11 = 4 Ã— 3 -1

55 – 25 = 30 = 11 Ã— 3 – 3

140 – 55 = 85 = 30 Ã— 3 – 5

? = 140 + 85 Ã— 3 – 7 = 140 + 248 = 388 - 1200, 480, 192, 76.8, 30.72, 12.288, ?
5.41003.11224.91524.08455.8102Option C

1200 / 2.5 = 480

480 / 2.5 = 192

192 / 2.5 =76.8

76.8 / 2.5 = 30.72

30.72 / 2.5 = 12.288

? = 12.288 / 2.5 = 4.9152 - 963, 927, 855, 747, 603, 423, ?
210215198200207Option E

963 – 1 Ã— 36 = 963 – 36 = 927

927 – 2 Ã— 36 = 927 – 72 = 855

855 – 3 Ã— 36 = 855 – 108 = 747

747 – 4 Ã— 36 = 747 – 144 = 603

603 – 5 Ã— 36 = 603 – 180 = 423

? = 423 – 6 Ã— 36 = 423 – 216 = 207 - The height of a room is 40% of its semiperimeter. It cost Rs 260 to paper the walls of the room with paper 50 cm wide at the rate of Rs 2 per m allowing an area of 15 m2 for doors and windows. What is the height of the room ?
10m6m4m12m9mOption C

Let the length, breadth and height of the room be l, b and h respectively.

Then, h = 0.4 ( l + b)

Area of the four walls = 2 (l + b) h = 2 (l + b) Ã— 0.4 (l + b) = 0.8 (l + b)^2

Required area where paper has to be pasted = 4/5 (l + b)^2 – 15

Now, area of paper = area of wall Length Ã— breadth = 4/5 (l + b)^2 – 15

Length = [4/5 (l + b)^2 â€“ 15]/1/2

Given, 2*2[4/5 (l + b)^2 â€“ 15] = 260

=> (l + b)^2 = 320

=> (l + b)^2 = 100

=> (l + b) = 10

=>h = 0.4 Ã— 10 = 4 m - Kamya purchased an item of Rs 46,000 and sold it at a loss of 12 percent. With that amount she purchased another item and sold it at a gain of 12 percent. What was her overall gain/loss ?
Loss Rs.666.2Gain Rs.650.15Gain Rs.699.8Loss Rs.662.4Loss Rs.677.5Option D

First S.P. = 46000 * 88/100 = Rs. 40480

Second S.P. = 40480 * 112/100 = Rs. 45337.6

Loss = Rs. (46000 – 45337.6) = Rs. 662.4 - A grocer purchased 2 kg. of rice at the rate of Rs. 15 per kg. and 3 kg. of rice at the rate of Rs. 13 per kg. At what price per kg should he sell the mixture to earn 33(1/3)% profit on the cost price ?
Rs.17.4Rs.15.7Rs.20.2Rs.18.4Rs.10.5Option D

2 kg of rice at Rs. 15/kg + 3 kg of rice at Rs. 13/kg Total weight = 2 + 3 = 5 kg

Total cost price = (2 Ã— 15) + (3 Ã— 13) = 30 + 39 = Rs. 69

Cost price per kg of the mixture = 69/5 = Rs.13.80

Selling price to get 33(1/3) % profit = [10 + 33 (1/3)]/100Ã— Rs 13.80

= 400Ã— Rs 13.80/3*100

= 4/3 Ã— Rs 13.80

= Rs 18.40 - A bus started its journey from Ramgarh and reached Devgarh in 44 minutes with its average speed of 50 km/hour. If the average speed of the bus is increased by 5 km/hour, how much time will it take to cover the same distance ?
60 mins.50 mins.70 mins.40 mins.20 mins.Option D

Distance between Ramgarh and Devgarh = 50 * 44/60

= 110/3 km

New speed = 55 kmph = 55/60 km/minute

Required time = Distance/Speed

= 110/3 Ã— 60/55 = 40 minutes - In how many different ways can 4 blue beads and 3 red beads be arranged in a row such that all the blue beads are together and all the red beads are together.
