Given:

The average salary of all the employees = Rs. 25,000.

The average salary of 10 employees = Rs. 30,000

The average salary of the rest is Rs. 15,000

Formula used:

Average = Total sum of all values/Number of values

Solution:

Let the number of the total employee be x.

⇒ 25000 × x = (30000 × 10) + (15000 × (x - 10)

⇒ 25000x = 300000 + 15000x - 150000

⇒ 25000x - 15000x = 300000 - 150000

⇒ 10000x = 150000

⇒ x = 150000/10000

⇒ x = 15

Given

Revenue from excise = 120 millions

Revenue from miscellaneous= 40 millions

Concept used

Central angle:

The angle formed by the two radii of the circle is known as the central angle. The circle completes an angle of 360°.

Solution

The sum of  taxes collected by a Government :

⇒ 80 + 120 + 140 + 80 + 40 = 460 millions

⇒ 460 million represents 360°

⇒ 1 millions = 360°/460 = 0.78º

The difference between revenue collected from excise and miscellaneous = 120 - 40 = 80 million

⇒ 80 million = 0.78º × 80

⇒ 62.6º

Given:

Distance = 28 km

Speed of A = 4 km/hr

Speed of B = 3 km/hr

Formula used:

Distance = speed × time

Solution:

Let the distance between Q & R be x.

Since A and B walk at the same time we can conclude T_A = T_B

⇒ (28 + x)/4 = (28 - x)/3

⇒ 3(28 + x) = 4(28 - x)

⇒ 84 + 3x = 112 - 4x

⇒ 7x = 28

⇒ x = 4 km

Distance between P & R = 28 – 4 = 24 km

Given:

x - y = 2280  ....(i)

⇒ 10.5% of x = 15.5% of y

Solution:

Let the two numbers be x and y.

⇒ 10.5% of x = 15.5% of y

⇒ 10.5x = 15.5y

⇒ x/y = 15.5/10.5

⇒ x/y = 31/21

Let x and y be 31a and 21a respectively.

Putting the values in (i):

⇒ 31a - 21a = 2280

⇒ 10a = 2280

⇒ a = 228

Now,

x = 31 × 228 = 7068

y = 21 × 228 = 4788

Solution

⇒ (9876543)/25

Dividing and multiplying the expression by 4.

⇒ (9876543)/25 × 4/4

⇒ (39506172)/100

⇒ 395061.72

Given

Ratio of their income = 5 : 7

Ratio of their monthly expenditures = 5 : 9

Each saving = Rs. 1500 

Concept used:

Savings = Income - expenditure

Solution

Let their income be 5x and 7x and their monthly expenditure be 5y and 9y.

Saving of A will be:

⇒ 5x - 5y = 1500    ....(i)

Saving of B will be:

⇒ 7x - 9y = 1500     ....(ii)

Solving both the equation:

We get x = 600 and y = 300

∴ Their monthly income will be 5x = 3000 and 7x = 4200

Hence their monthly income will be Rs. 3000 and Rs. 4200

Given:

Principal = 22500

Rate = 6.5%

Time = 2 yrs

Formula used:

S.I = PRT/100

⇒ S.I = (222500 × 6.5 × 2)/100

⇒ 225 × 13 = 2925

The amount to be paid back is:

⇒ 22500 + 2925 = 25425

Given

Ramesh speed = 66.8 km/hr

Formula used

Distance = Speed × time

Solution

Ramesh's speed in m/s:

⇒ 66.8 × 5/18

⇒ 334/18 m/s

⇒ 5 minutes = 300seconds

Distance covered by him in 5 minutes, 

⇒ 334/18 × 300

⇒ 5566.66 m ~ 5567 m

Given:

⇒ (49 × 14)³ ÷ (28 × 21)³ × (54432) ÷ 36 = 7^x

Concept used: 

Calculation:

⇒ (49 × 14)3 ÷ (28 × 21)3 × (54432) ÷ 36 = 7x

⇒ (7³ × 2)³ ÷ (7² × 2² × 3)3 × 1512 = 7x

⇒ (7⁹ × 2³) ÷ (7⁶ × 2⁶ × 33) × 1512 = 7x

⇒ (7³)/(23 × 33) × 1512 = 7x

⇒ (73)/(8 × 27) × 1512 = 7x

⇒ (73) × 7 = 7x

⇒ 7⁴ = 7x

Since the base is the same we can equate the power:

∴ x = 4.

Solution

Daily sale of all chocolates = 10 + 12 + 14 + 16 + 18 + 15 + 12 + 3 = 100

⇒ 10 × 100 = 1000 kit-kat

But as mentioned, the shopkeeper has only 500 Kit-kat:

⇒ 1000 - 500 = 500

So instead of 500 KitKat, 500 dairy milk are sold

The total sale of dairy milk will be:

⇒ (12 × 100) + 500

⇒ 1700 Dairy milk

∴ 1700 chocolates of dairy milk chocolates sold that day.

Given

⇒ 19.678 + 348.91 - ? = 278.63

Solution

Let the missing value be x.

⇒ 19.678 + 348.91 - x = 278.63

⇒ x = 19.678 + 348.91 - 278.63

⇒ x = 368.588 - 278.63

⇒ x = 89.958

Solution

In 2015, rice is more than wheat by:

⇒ (15 - 10)/10 × 100

⇒ 50%

In 2016, rice is more than wheat by:

⇒ (20 - 15)/15 × 100

⇒ 33.33%

In 2017, rice is more than wheat by:

⇒ (22 - 18)/18 × 100

⇒ 22.22%

In 2018, rice is more than wheat by:

⇒ (25 - 22)/22 × 100

⇒ 13.63%

In 2019, rice is more than wheat by:

⇒ (30 - 25)/25 × 100

⇒ 20%

In 2020, rice is more than wheat by:

⇒ (34 - 28)/28 × 100

⇒ 21.42%

Hence, in total 4 years, the production of rice is more than 20% as compared to the wheat produced that year.

Concept used:

The longest rod that can be placed in the cuboid is the diagonal of the cuboid.

Formula used:

Diagonal of cuboid = √l² + b² + h²

Solution:

⇒ √l2 + b2 + h2

⇒ √(102 + 82 + 62)

⇒ √(100 + 64 + 36)

⇒ √(200)

Given:

A shopkeeper buys 120 T-shirts =  Rs. 400/each

He sold 40 T-shirts = 8% profit

Overall profit = 10%

Formula used:

Profit% = (SP - CP)/CP × 100

Solution:

The total cost of 120 t-shirts = 120 × 400

⇒ 48000

He sold 40 T-shirts at 8% profit i.e:

⇒ 40 × 400 × 108/100

⇒ 40 × 432

⇒ 17280

If he wants 10% profit on the whole then:

⇒ 120 × 400 × 110/100

⇒ 52800

Now, he should sell the remaining 80 t-shirts for:

⇒ 52800 - 17280

⇒ 35520

The selling price of each t-shirt for these 80 t-shirts = 35520/80

⇒ 444

While the cost price of each t-shirt was = 400

The profit% for the remaining 80 t-shirts:

⇒ (444 - 400)/400 × 100

⇒ 11%

Given

A, B and C can complete a piece of work in 32, 16 and 40 days respectively

Formula

Total work = Efficiency × Time taken

Solution

Let the total work done be (LCM of 32,16 and 40) = 160 units

Efficiency of A = 160/32 = 5 units/day

Efficiency of B = 160/16 = 10 units/day

Efficiency of C = 160/40 = 4 units/day

Now, the total efficiency of A, B and C = 5 + 10 + 4 = 19 units/day

Working together, they will complete the same work in:

⇒ 160/19 days

Solution

⇒ (1/2) + (1/6) + (1/12) + (1/20) + (1/30) + (1/42) + (1/56) + (1/72) + (1/90)

This expression can also be written as:

⇒ (1 - 1/2) + (1/2 - 1/3) + (1/3 - 1/4) + (1/4 - 1/5) + (1/5 - 1/6) + (1/6 - 1/7) + (1/7 - 1/8) + (1/8 - 1/9) + (1/9 - 1/10)

⇒ 1 - 1/2 +  1/2 - 1/3 + 1/3 - 1/4 + 1/4 - 1/5 + 1/5 - 1/6 + 1/6 - 1/7 + 1/7 - 1/8 + 1/8 - 1/9 + 1/9 - 1/10

⇒ 1 - 1/10

⇒ 9/10 = 0.9
