23, 25, 53, 163, 657, 3291, ?

=> 23 Ã— 1 + 2 = 25

=> 25 Ã— 2 + 3 = 53

=> 53 Ã— 3 + 4 = 163

=> 163 Ã— 4 + 5 = 657

=> 657 Ã— 5 + 6 = 3291

=> ? = 3291 Ã— 6 + 7 = 19746 + 7 = 19753 - 3, 4, 12, ?, 196

3, 4, 12, ?, 196

=> 3 Ã— 1 + l^2 = 3 + 1 = 4

=> 4 Ã— 2 + 2^2 = 8 + 4= 12

=> 12 Ã— 3 + 3^2 = 36 + 9 = 45

=> 45 Ã— 4 + 4^2 = 180 + 16 = 196 - 0, 5, 18, 43, 84, 145, ?
230202215222200Option A

0, 5, 18, 43, 84, 145, ?

=> 0 + 5 = 5

=> 5 + 13 = 18

=> 18 + 25 = 43

=> 43 + 41 = 84

=> 84 + 61 = 145

=> ? = 145 + 85 = 230 - 45, 46, 70, 141, ?, 1061.5

45, 46, 70, 141, ?, 1061.5

=> 45 Ã— 1 + 1 = 46

=> 46 Ã— 1.5 + 1 = 70

=> 70 Ã— 2 + 1 = 141

=> 141 Ã— 2.5 + 1 = 352.5 + 1 = 353.5 - ?, 16, 28, 58, 114, 204
108141920Option C

?, 16, 28, 58, 114, 204

=> 14 + 1 Ã— 2 = 16

=> 16 + 3 Ã— 4 = 16 + 12 = 28

=> 28 + 5 Ã— 6 = 28 + 30 = 58

=> 58 + 7 Ã— 8 = 58 + 56 = 114

=> 114 + 9 Ã— 10 = 114 + 90 = 204 - Three containers, A, B and C are having mixtures of milk and water in the ratio 1 : 5, 3 : 5 and 5 : 7 respectively. If the capacities of the containers are in the ratio 5 : 4 : 5, then find the ratio of the milk to the water, if the mixtures of all the three containers are mixed together.
35 : 15144 : 10143 : 10555 : 11153 : 115Option E

By question ratio of milk and water

= [(1/6)*5 + (3/8)*4 + (5/12)*5] : [(5/6)*5 + (5/8)*4 + (7/12)*5] = 106 : 230

= 53 : 115 - Two cars start together in the same direction from the same place. The first goes with a uniform speed of 10 km/h. The second goes at a speed of 8 km/h in the first hour and increase the speed by 1/2 km each succeeding hour. After how many hours will the second car overtaken the first if both go non stop ?
2 h5 h7 h9 h4 hOption D

Let second car overtake the first car after n h.

Distance covered by first car = Distance covered by second car

=> 10n = 8 + [8+(1/2)] + [8+(1/2)] + [8+ (n-1)/2] => 10n = 8n + Â½[1+2+â€¦â€¦â€¦+(n-1)] => 10n = 8n +1/2[n(n-1)/2] => 2n = Â¼(n^2 – n)

=> n = 9

Hence the answer is 9 h. - Peter got 30% of the maximum marks in an examination and failed by 10 marks. However, Paul who took the same examination got 40% of the total marks and got 15 more than the passing marks in the examination. What were the passing marks in the examination ?
8077908574Option D

Let the maximum marks be x.

Then, x Ã— 30% + 10 = x Ã— 40% – 15

=> x Ã— 10% = 25

=> x = 250

Passing marks = 250 Ã— 30/100 + 10

= 85 - Mr. Sarang invests 6% of his monthly salary i.e. Rs.2,100 on insurance policies. Also he invests 8% of his monthly salary on family mediclaim policies and another 9% of his salary on NSCs. What is the total annual amount invested by Mr. Sarang ?
Rs.74520Rs.95200Rs.82000Rs.96600Rs.89500Option D

6% of Sarangâ€™s monthly income = Rs. 2100

Sarangâ€™s monthly income = 2100 * 100/6 = Rs. 35000

Percentage of monthly investment = 23%

Sarangâ€™s annual investment = 12 Ã— 35000 Ã— 23/100

= Rs. 96600 - 6 men can complete a piece work in 12 days. 8 women can complete the same piece of work in 18 days whereas 18 children can complete the piece of work in 10 days. 4 men, 12 women and 20 children work together for 2 days. If only men were to complete the remaining work in 1 day how many men would be required totally ?
2036302533Option B

72 men = 144 women = 180 children

2 men = 4 women = 5 children

4 men +12 women + 20 children

= 4 men+ 6 men+ 8 men

= 18 men

When 6 men do 1 work in 12 days 18 men will do the same in 4 days.

In 2 days half work will done.

Remaining work = Â½ M1*D1/W1 = M2*D2/W2

=> 1/2 Ã— 6 Ã— 12 = l Ã— M2

=> M2 = 36 = Number of men
