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.

Except Lady finer, all other options can be modified through the process of genetic engineering.

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:
