Forecast the Growth Rate for the year 1995 from the following data:
In the growth rate the pattern followed is:
3.5 + 0.2 = 3.7
3.7 + 0.2 × 2 = 3.7 + 0.4 = 4.1
4.1 + 0.4 × 2 = 4.1 + 0.8 = 4.9
4.9 + 0.8 × 2 = 4.9 + 1.6 = 6.5
Now, 6.5 + 1.6 × 2 = 6.5 + 3.2 = 9.7
Thus 9.7 is the answer.

Two pipes can fill a tank in 10 hours and 12 hours respectively, while a third pipe empties the full tank in 20 hours. If all the three pipes operate simultaneously, in how much time the tank will be filled?
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

In a group of 50 students, 25 play Hockey, 30 play Football, and 8 play neither game. What is the number of students who play both Hockey and Football?
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.

Two numbers A and B are 22% and 34% less then a third number C. Find by what percentage is the number B less than the number A?
A = C – 0.22C = 0.78C
B = C – 0.34C = 0.66C
∴ Required % = ((0.78C – 0.66C)/0.78C) × 100 = 15.3 ≈ 15%
∴ B is less than A by 15%
'Yug Purush, Bharat Ratna, Atal ji' has been written by _______.

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.
A and B together can complete a work in 24 days. B alone does 1/3rd part of this work in 12 days. How many days will A alone take to complete the remaining work?
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

The cost of Type 1 material is Rs. 15 per kg and Type 2 material is Rs. 20 per kg. If both Type 1 and Type 2 are mixed in the ratio of 2 : 3, then what is the price per kg of the mixed variety of material?
⇒ 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
The surface area of the three coterminous faces of a cuboid are 6, 15, 10 sq.cm respectively. Find the volume of the cuboid.
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 :
⇒ l^{2} b^{2} h^{2 }= 6 x 15 x 10
⇒ Volume = l x b x h
⇒ Volume =6x15x10−−−−−−−−−√=6x15x10
∴ Volume is 30

A man travels 30 km at speed 10 km/h and next 40 km at 20 km/h and there after travel 60 km at 30 km/h. His average speed is
As per the given data, we get
Time taken for the first 30 km = distance /speed = 30/10 = 3 hours
Time taken for the next 40 km = 40/20 = 2 hours
Time taken for the next 60 km = 60/30 = 2 hours
Total time = 3 + 2 + 2 = 7 hours
Total distance = 30 + 40 + 60 = 130 km
∴ Average speed = total distance/total time = 130/7 = 18.6 km/hr

⇒ 5 + (2^{2} + 5) × 4 – (6 ÷ 2)
⇒ 5 + 9 × 4 – 3
⇒ 5 + 36 – 3
⇒ 41 – 3
∴ 5 + (2^{2} + 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
Find the value of x in the given expression.17% of x = 66% of 128 – 31% of x
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

The average of 8 consecutive numbers is K. If next 4 numbers are also added, the average increased by
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]
The present age of Akhil and Vinay is 27 and 36 years respectively. After how many years from now, will the ratio of their ages be 4 : 5?
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
A vessel contains liquids A and B in ratio 5 : 3. If 16 litres of the mixture are removed and the same quantity of liquid B is added the ratio becomes 3 : 5 What quantity does the vessel hold?
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

If the price of pen decreases by 20%, then a man can buy 10 more pens for Rs 100. What is the new price (in Rs.) of each pen?
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
A certain sum of money triples itself in 5 years at simple interest. In how many years it will be five times?
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

A shopkeeper sells a table at a discount of 20% and earns a profit of 60%. If he sells the same table at 40% discount, then what will be his new profit percent?
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%

Question:
What was the percentage decrease in the number of scholars from Tamil Nadu from 2000 to 2001?
% 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

Two trains are moving in the same directions at speed of 43 km/h and 51 km/h respectively. The time taken by the faster train to cross a man sitting in the slower train is 72 seconds. What is the length (in metres) of the faster train?
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

If ‘ ÷ ’ means ‘ × ’, ‘ – ‘ means ‘ ÷ ’, ‘ + ’ means ‘– ‘ and ‘ × ’ means ‘ + ’ then what is the value of:180 ÷ 6 + 36 – 9 × 18
Changing operators as given format.
÷ → ×
– → ÷
× → +
+ → –
→ 180 ÷ 6 + 36 – 9 × 18 will be 180 × 6 – 36 ÷ 9 + 18
→ 180 × 6 – 4 + 18
→ 1094.
Hence, answer is 1094.
