Pattern is 2^2, 3^2-1, 4^2, 5^2 – 1, 6^2 and so on.

? = 48 - 3, 22, ?, 673, 2696, 8093

(/ 2 – 1), (/ 2 – 1), (/2 – 1)…

=>142/2 – 1 = 71 –1 = 70 - 17, 9, ?, 16.5, 35, 90
1510212517Option B

(×0.5 + 0.5), (×1 + 1), (×1.5 + 1.5), (×2 + 2)

=> 9 × 1 + 1 = 10 - 730, 675, 626, 575, ?

Pattern is (27^2+1),( 26^2 – 1), (25^2+1),(24^2 – 1), and so on.

? = 23^2+ 1= 530 . - Two pipes A and B can fill a tank in 15 hours and 20 hours respectively while a third pipe C can empty the full tank in 25 hours. All the three pipes are opened in the beginning. After 10 hours, C is closed. Now how much time more is required to fill the tank?
5 hrs.3 hrs.2 hrs.9 hrs.4 hrs.Option C

Let the required time be T hours.

Now part filled by A in (10 + T) hours + part filled by B in (10 + T) hours + part empty by C in 10 hours = 1

=>[𝑇 + 10]/15+[𝑇 + 10]/20−10/25=1

=>𝑇= 2 hrs. - A, B and C can do a piece of work individually in 8, 12 and 15 days, respectively. A and B start working but A quits after working for 2 days. After this, C joins B till the completion of work. In how many days will the work be completed?
3(1/9) days5(8/9) days2(2/5) days5(3/7) days7(8/9) daysOption B

Work was done by A and b in 1 day

=1/8+1/12=5/24 2 day’s work of A and B = 10/24

After 2 day’s A left the work

∴ Remaining work =1−10/24=14/24

One day work of B and C together =1/12+1/15=9/60

So, the number of days required by B and C to finish work

=14/24/9/60 =14/24×60/9 =35/9

∴ Total days to complete the work

=2+35/9 = 53/9 = 5(8/9) days - Mahesh borrows Rs.7500 from a bank at SI. After 5 years he paid Rs.3500 to the bank and at the end of 8 yrs from the date of borrowing he paid Rs.6500 to the bank to settle the account. Find the rate of interest.
9.05%7.02%4.00%5.05%8.03%Option D

Total interest

=(interest on 7500 for 5 years)+(interest on 4000 for 3 years)

=> 7500×5×𝑅 /100 + 4000×3×𝑅/ 100 = 3500+6500-7500

=> 375R+120R=2500

=>R=5.05% - 85 kg of a mixture contains milk and water in the ratio 27 : 7. How much more water is to be added to get a new mixture containing milk and water in the ratio 3 : 1?
5 kg.8 kg.7 kg.10 kg.4 kg.Option A

Milk in 85 kg of mixture = (85×27/34) kg =135/2 kg.

Water in it = (85−135/2) kg =352 kg.

Let x kg of water be added to it.

Then, (135/2)/(35/2 + 𝑥)= 31

=>135/35+2𝑥=31

=>105+6𝑥=135

=> 6𝑥=30

=>𝑥=5.

Hence,Quantity of water to be added = 5 kg. - Tickets numbered 1 to 20 are mixed up and then a ticket is drawn at random. What is the probability that the ticket drawn has a number which is a multiple of 3 or 5?
11/179/2010/192/115/9Option B

S = {1, 2, 3, 4, …., 19, 20}.

Let E = event of getting a multiple of 3 or 5 = {3, 6 , 9, 12, 15, 18, 5, 10, 20}.

P(E) = n(E)/n(S) =9/20 .
