Time taken by A , B and C to fill/empty the tank completely = 10 , 12 and 20 hours respectively

Hence part of tank filled by A, B and emptied by C in 1 hour = 1/10, 1/12 and 1/20 respectively

Part of tank filled by all 3 pipes in 1 min =1/10+1/12−1/20=1/10+1/12−1/20

=660+560−360=660+560−360

=860=860

= 2/15

Hence it will take 15/2 hours ie 7 hours and 30 mins to completely fill the tank

Mizoram is the second most literate state in all of India (88%), second only to Kerala, with Serchhip and Aizawl districts being the two most literate districts in India (literacy rate is 98.76% and 98.50%),both in Mizoram. 

Total students = 50

Student who play hockey = 25

Student who play football = 30

Students who play neither football nor hockey = 8

Total students = (Student who play hockey) + (Students who play football) – (Students who play both hockey and football) + (Students who neither play hockey nor football)

50 = 25 + 30 – (Students who play both hockey and football) + 8

Students who play both hockey and football = 13

So, total 13 students play both hockey and football.

Here, According to the Venn diagram,

Doctors who are not  Engineers but Good speakers = 6.

Actual amount they have to got -

But mistakenly they got the amount in the ratio = 3 : 4 : 2

Hence, A and B gained in the transaction.

208, 225, 259, 310, ?, 463

225 – 208= 17

259 – 225= 34

310 – 259= 51

The value increases in multiples of 17.

The next number will be increased by 68, 310 + 68 = 37

Hence the correct option is 378

Putting A = 1, B = 2, C = 3, D = 4, ....., X = 24, Y = 25, Z = 26,

we have since K = 11,

so value corresponding to missing letter = (27 – 11) = 16.

So, the missing letter is the 16^th letter of the English alphabet, which is P.

Work done by B in one day = (1/3)/12 = 1/36

Work done by both A and B in one day = 1/24

Work done by A in one day = (1/24) – (1/36) = 1/72

Time taken by A alone to complete the work = 1/(1/72) = 72 days

∴ Time taken by A alone to complete the work = 72 days

Remaining work = 1 - 1/3 = 2/3

A alone take to complete the remaining work = 72 × (2/3) = 48 days

⇒ Cost Price (C.P) of Type 1 material is Rs. 15 per kg

⇒ C.P of Type 2 material is Rs. 20 per kg

⇒ Type 1 and Type 2 are mixed in the ratio of 2 : 3 

⇒ C.P of the resultant mixture 

⇒ {(15 × 2) + (20 × 3)}/(2 + 3)

⇒ (30 + 60)/5 = 90/5

⇒ (30 + 60)/5 = 18

∴ Price per kg of the mixed variety of material = Rs.18

If l, b, h be the dimensions of the cuboid,

then volume of the cuboid = l x b x h 

⇒ l x b = 6

⇒ l x h = 15

⇒ b x h = 10

multiplying all the three equations we get :

⇒ l² b² h² = 6 x 15 x 10

⇒ Volume = l x b x h

⇒ Volume =6x15x10−−−−−−−−−√=6x15x10

∴ Volume is 30

⇒ 5 + (2² + 5) × 4 – (6 ÷ 2)

⇒ 5 + 9 × 4 – 3

⇒ 5 + 36 – 3

⇒ 41 – 3

∴ 5 + (2² + 5) × 4 – (6 ÷ 2) = 38

Computing,

4 × 11 × 5 × 5 = 1100

Sum of decimal places = 2 + 1 + 3 + 1 = 7

Hence,

(0.04 × 1.1 × 0.005 × 0.5)

= 0.0001100

= 0.00011

17% of x = 66% of 128 – 31% of x

⇒ 0.17x = (0.66 × 128) – 0.31x

⇒ 0.17x + 0.31x = 84.48

⇒ 0.48x = 84.48

⇒ x = 84.48/0.48

⇒ x = 176

If 8 numbers are 1, 2, 3, 4, 5, 6, 7, 8

The average of these numbers is

⇒ (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8)/8 = 4.5

If next four numbers are added, then,

⇒ (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12)/12 = 6.5

∴ The average is increased by 2

[Note: No matter which consecutive numbers we choose, the increase or decrease in average is same]

Given the present ages of Akhil and Vinay are 27 and 36 years respectively

⇒ Let us consider after ‘x’ years the ratio of their ages will be 4 : 5

Their ages after ‘x’ years will be (27 + x) and (36 + x) years respectively

⇒ From the condition,

(27 + x)/(36 + x) = 4/5

⇒ (27 + x) × 5 = (36 + x) × 4

⇒ 135 + 5x = 144 + 4x

⇒ 5x – 4x = 144 – 135

⇒ x = 9 years

∴ The ratio of their ages will be in the ratio 4 : 5 after 9 years from the present ages

 Suppose the vessel contains 5x litres and 3x litres of liquids A and B respectively.

The removed quantity contains = 16/(5 + 3) × 5 = 10litres of A and 16 - 10 = 6 litres of B

Now, (5x - 10) : (3x - 6 + 16) = 3 : 5

⇒ (5x - 10) / (3x + 10) = 3/5

⇒ 25x - 50 = 9x + 30

⇒ 16x = 80

⇒ x = 5

∴ Capacity of vessel = 8x = 8 × 5 = 40

⇒ 2.36 × 3.47 + 5.4

⇒ 8.1892 + 5.4

⇒ 8.19 + 5.4

⇒ 13.59

∴ 2.36 × 3.47 + 5.4 = 13.59

Let the price of 1 pen initially be Rs. X

⇒ Number of pens he can buy now = 100/x

 After 20% discount price of 1 pen = x(1 – 20/100) = 0.8x

⇒ Number of pens he can buy now = 100/0.8x

According to problem statement,

⇒ 100/0.8x – 100/x = 10 pens

⇒ (100/x) × 1/4 = 10

⇒ x = 2.5

∴ the new price is 2.5 × 0.8 = Rs. 2

Let rate be r, principle amount be p and the number of years bet

After 5 years,

⇒ Simple Interest = 3p – p = 2p

⇒ 2p = (p × r × 5)/100

⇒ r = 40

After t years,

⇒ Simple Interest = 5p – p = 4p

⇒ 4p = (p × 40 × t)/100

⇒ t = 10

∴ It will take 10 years

Let the Cost price of the table be a

Since he gains a profit of 60%, the selling price = a + (60/100) x a = 1.6a

Let the Marked price of the table be b

⇒ b – (20/100) x b = 1.6a

⇒ b = 2a

Now, if he sells the table at 40% discount

⇒ New selling price will be = 2a – (2a) x (40/100)

⇒ New selling price = 1.2a

∴ New profit percent = [(1.2a – a)/a] x 100 = 20%

As just looking into the table, we can say no state except Delhi has shown continuous growth in number of scholars going to abroad over the years.

∴ Option 3 is correct

Average = Sum/Number of terms

Sum = 900 + 1200 + 940 + 220 + 298 = 3558

Number of terms = 5

∴ Average = 3558/5 = 711.6

% increase = Increase/Original Value

% increase from 2000 to 2001 = [ {Value (2000) - Value(2001)}/Value(2000)] × 100

⇒ % increase from 2000 to 2001 = [(340 - 220)/340] × 100 = 120 × 100/340

∴ % increase from 2000 to 2001 ≈35.3%

For this, calculate the total number of scholars moved abroad over the given years

West Bengal = 580 + 340 + 450 + 900 + 760 = 3030

Delhi = 460 + 500 + 720 + 1200 + 1360 = 4240

Maharashtra = 670 + 750 + 430 + 940 + 860 = 3650

Tamil Nadu = 200 + 600 + 340 + 220 + 500 = 1860 → Minimum

Kerala = 128 + 450 + 876 + 298 + 567 = 2319

∴ Tamil Nadu shows the least number of scholars going abroad over the years

We know that

⇒ 5/113 = 0.04

⇒ 7/120 = 0.05

⇒ 13/145 = 0.089

⇒ 17/160 = 0.10625

∴ 17/160 is largest

Given: The speed of 2 trains = 43 km/hr and 51 km/hr

Relative velocity of one train w.r.t. another = (51 - 43)km/hr = 8 km/hr

Relative velocity in m/s = 8 × (5/18) m/s

⇒ Distance covered by the train in 72 sec = 8 × (5/18) × 72 = 160

Since, this is the distance covered in crossing the man

Hence, the length of faster train = 160 m
