Given:

Principal = Rs. 10,000

Rate = 10% per annum

Time = 3 years

Formula used:

For Compound interest,

(i) A = P{1 + (R/100)}ⁿ

where,

A = Amount

P = Principal

R = Rate

n = Time

(ii) A = P + CI

where,

CI = Compound interest

Calculations:

A = P{1 + (R/100)}n

⇒ A = 10,000{1 + (10/100)}³

⇒ A = 10,000(11/10)3

⇒ A = 10,000 × (1331/1000)

⇒ A = Rs. 13,310

A = P + CI

⇒ 13,310 = 10,000 + CI

⇒ CI = 13,310 – 10,000

⇒ CI = Rs. 3,310

∴ The compound interest is Rs. 3,310.

1000 → Rs. 10,000

⇒ 1 → Rs. 10

⇒ 331 → Rs. 3,310

∴ The compound interest is Rs. 3,310.

Given:

Selling price = Rs. 2,250

Profit percentage = 12.5%

Formula used:

(i) Profit Percentage = {(SP - CP)/CP} × 100

(ii) Profit = SP - CP

where,

SP = Selling price

CP = Cost price

Calculations:

Profit Percentage = {(SP - CP)/CP} × 100

⇒ 12.5 = {(2,250 - CP)/CP} × 100

⇒ 1/8 = {(2,250 - CP)/CP}

⇒ CP = (2,250 - CP) × 8

⇒ CP = 18,000 - 8CP

⇒ 9CP = 18,000

⇒ CP = Rs. 2,000

Profit = SP - CP

⇒ 2,250 - 2,000

⇒ Rs. 250

∴ The amount of profit was Rs. 250.

CP × 112.5% = 2,250

⇒ CP × 9/8 = 2,250

⇒ CP = Rs. 2,000

Profit = 2,250 - 2,000

⇒ Rs. 250

∴ The amount of profit was Rs. 250.

Ratio of prize money = 3 : 5 : 7

R got 1000 rupees more than P.

Calculations:

Let the money received by P, Q and R be 3x, 5x and 7x respectively.

7x - 3x = 1000

⇒ 4x = 1000

Given:

Length of diagonal of rectangle = 11 cm

Half of perimeter = 13 cm

Formula used:

(i) Area of rectangle = l × b

(ii) Perimeter of rectangle = 2(l + b)

(iii) Diagonal of rectangle = √(l2 + b2)

where,

l = length of rectangle

b = breadth of rectangle

(iv) (a + b)2 = a2 + b2 + 2ab

Calculations:

Diagonal = √(l² + b²)

⇒ 11 = √(l2 + b2)

⇒ l2 + b2 = 121      ----(i)

Perimeter = 2(l + b)

Half of perimeter = 2(l + b)/2

⇒ 2(l + b)/2 = 13

⇒ l + b = 13      ----(ii)

On squaring both sides,

⇒ (l + b)² = (13)²

⇒ l2 + b2 + 2lb = 169

⇒ 121 + 2lb = 169

⇒ 2lb = 169 - 121

⇒ 2lb = 48

⇒ lb = 24 square cm

∴ The area is 24 square cm.

Given:

(x2 - y2)/(x - y) =?

Formula used:

(a2 - b2) = (a - b)(a + b)

Calculations:

(x2 - y2)/(x - y) =?

⇒ (x - y)(x + y)/(x - y) =?

⇒ x + y = ?

∴ The value of ? is x + y.

Additional Information

(i) (a + b)² = (a² + b² + 2ab)

(ii) (a - b)2 = (a2 + b2 - 2ab)

(iii) (a³ - b³) = (a - b)(a2 + b2 + ab)

(iv) (a3 + b3) = (a + b)(a2 + b2 - ab)

(v) (a + b)³ = a³ + b³ + 3ab(a + b)

(vi) (a - b)3 = a3 - b3 - 3ab(a - b)

Given statement: A woman has no siblings. Pointing to a photo, the woman says, "This woman's mother is my mother's daughter".

Below given diagram shows the above relation:

Hence, Women's daughter is correct.

Given:

Selling price = Rs. 1,458

Cost price = Rs. 1,350

Formula used:

Profit Percentage = {(SP - CP)/CP} × 100

where,

SP = Selling price

CP = Cost price

Calculations:

Profit Percentage = {(SP - CP)/CP} × 100

⇒ {(1,458 - 1,350)/1,350} × 100

⇒ (108 /1,350) × 100

⇒ (2/25) × 100

⇒ 8%

∴ The profit percentage is 8%.

The correct answer is Evaporation.

Key Points

• Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.
• The oceans, seas, lakes, and rivers provide nearly 90 percent of the moisture in the atmosphere via evaporation, with the remaining 10 percent being contributed by plant transpiration.

NOTE:

Genetic Engineering - Genetic engineering, also called genetic modification or genetic manipulation, is the direct manipulation of an organism's genes using biotechnology.

Hence, Lady Finger is correct.

Given:

12tan A = 5

Concept used:

Using the concept of trigonometric ratios,

tanθ = Perpendicular/Base

cosecθ = Hypotenuse/ Perpendicular

Calculation:

12tanA = 5

⇒ tanA = 5/12

tanA = BC/AB

BC/AB = 5/12

In ΔABC,

By using Pythagoras theorem,

BC² + AB² = AC²

⇒ 5² + 12² = AC²

⇒ 25 + 144 = AC²

⇒ AC = √169

⇒ AC = 13

cosecA = AC/BC

⇒ cosecA = 13/5

∴ The value of cosecA is 13/5.

Given:

Husband's income = Rs. 45000

Wife's income = Rs. 35000

Donation amount = Rs. 5000

Concept used:

Percentage = Given value/Sum of total value × 100

Calculation:

Husband's income = Rs. 45000

Husband's new income = Husband's income – Donation

⇒ Husband's new income = 45000 – 5000

⇒ Husband's new income = Rs. 40000

Wife's income = Rs. 35000

Wife's new income = Wife's income – Donation

⇒ Wife's new income = 35000 – 5000

⇒ Wife's new income = 30000

Total income after donation =  Husband's new income + Wife's new income

⇒ Total income = 40000 + 30000

⇒ Total income = 70000

Required percentage = (Husband's new income)/(Total income) × 100

⇒ Required percentage = 40000/70000 × 100

⇒ Required percentage = 57.14%

∴ The percentage of the husband's income is 57.14% of their combined income.

Given:

Amount = Rs. 10920

Rate of interest = 10%

Time = 4 years

Formula used:

SI = P × R% × T

where, P = Principal, R = Rate of interest, T = Time 

Amount = P + SI

Calculation:

Let the principal sum be Rs. P.

Amount = Principal + SI

⇒ 10920 = P + P × R% × T

⇒ 10920 = P(1 + 10/100 × 4)

⇒ 10920 = P(1 + 2/5)

⇒ 10920 = 7P/5

⇒ P = Rs. 7800

∴ The sum of money he borrowed is Rs. 7800.

Given:

a2 + b2 = 80

a – b = 4

Formula used:

(a – b)² = a² + b² – 2ab

Calculation:

a – b = 4

⇒ (a – b)² = 4²               [Squaring both sides]

⇒ a2 + b2 – 2ab = 16

⇒ 80 – 2ab = 16

⇒ -2ab = 16 – 80

⇒ -2ab = -64

⇒ ab = 32

∴ The value of ab is 32.

Given:

We have to find the code for the word 'definitely'.

Possible codes for the word 'definitely' - 9, 1

Hence, Can't be determined is correct.

Given:

M can do work in 5 days

R can do work in 20 days

Concept used:

If a man can complete a work in x days then the man can complete 1/x work in 1 day.

Calculation:

Work done by M in 1 day = 1/5

Work done by R in 1 day = 1/20

Total work done by them together in 1 day = 1/5 + 1/20

⇒ Total work done by them together in 1 day = 5/20 = 1/4

Together they can complete the work in 1/(1/4) days

∴ M and R together can finish the work in 4 days.

If M can do work in x days and R can do work in y days, then together they can complete the work in (x × y)/(x + y) days

M and R together can do the work in (5 × 20)/(5 + 20) = 100/25

∴ M and R together can finish the work in 4 days.

Given:

4 cricketers played 13, 9, 5, and 11 innings

Mean = 9

Formula used:

Mean = Sum of all observations/Number of observations

Calculation:

Let the 5_th player played x innings.

Sum of all innings played by 5 players = 13 + 9 + 5 + 11 + x

⇒ Sum of all innings = 38 + x

Total players = 5

Mean = Sum of all innings played by 5 players/Total players

⇒ 9 = (38 + x)/5

⇒ 45 = 38 + x

⇒ x = 45 – 38 = 7

∴ Innings played by 5_th player is 7

Given:

⇒ 1328 = 8x 

⇒ x = 1328/8 = 166

The number of arts students = 3x = 3 × 166

∴ The number of arts students are 498

Concept used:

Follow BODMAS rule to solve this question, as per the order given below

Now,

Calculation:

(2 × 43 × 32) / (3 × 16)
