Given:

16 oranges sold for $1 gives 20% loss

Required profit = 60%

Formula Used:

SP = 1 dollar ÷ number of oranges

Loss: SP = 0.8 × CP

Profit: SP = 1.6 × CP

Calculation:

⇒ SP per orange = 1 ÷ 16 = 1/16

⇒ For 20% loss: SP = 0.8CP

⇒ CP = (1/16) ÷ 0.8

⇒ CP = (1/16) × (1 ÷ 0.8)

⇒ CP = (1/16) × 1.25

⇒ CP = 1/12.8

Now for 60% profit:

⇒ New SP per orange = 1.6 × CP

⇒ New SP = 1.6 × (1/12.8)

⇒ New SP = 1/8

⇒ If SP per orange is 1/8 dollars, oranges sold for $1:

⇒ Number of oranges = 1 ÷ (1/8)

⇒ Number of oranges = 8

∴ The correct answer is 8.

Given:

Shalini saves one-third of her income

Savings increase = 21%

Expenses increase = 15%

Income increase = x%

Formula Used:

Income = Savings + Expenses

New amount = Old amount × (1 + increase%)

Savings = Income − Expenses

Calculation:

Let income = 3 units

⇒ Savings = 1 unit

⇒ Expenses = 2 units

Income increases by x%:

⇒ New income = 3(1 + x/100)

Expenses increase by 15%:

⇒ New expenses = 2 × 1.15 = 2.3

New savings increase by 21%:

⇒ New savings = 1 × 1.21 = 1.21

Savings = Income − Expenses:

⇒ 3(1 + x/100) − 2.3 = 1.21

⇒ 3 + 0.03x − 2.3 = 1.21

⇒ 0.03x + 0.7 = 1.21

⇒ 0.03x = 0.51

⇒ x = 0.51 ÷ 0.03

⇒ x = 17

∴ The correct answer is 17%.

Given:

Given:

Principal = 1,900

Amount in 3 years = 2,100

New principal = 11,400

Time = 5 years

Formula Used:

Simple Interest = Amount − Principal

Rate = (SI ÷ (P × T)) × 100

Amount = Principal + Simple Interest

Calculation:

⇒ SI for 3 years = 2,100 − 1,900 = 200

⇒ Rate = 200 ÷ (1,900 × 3)

⇒ Rate = 200 ÷ 5,700

⇒ Rate = 1/28.5 per year

⇒ SI for 5 years on 11,400:

⇒ SI = 11,400 × (1/28.5) × 5

⇒ 11,400 ÷ 28.5 = 400

⇒ SI = 400 × 5 = 2,000

⇒ Amount = 11,400 + 2,000

⇒ Amount = 13,400

∴ The correct answer is ₹13,400.

Given:

20% of the students are under age 10

Students under age 10 = 24

Students over age 10 = one-third of students under age 10

Formula Used:

Total students under 10 = 20% of total

Over-10 students = (1/3) × under-10 students

Total students = under-10 + over-10

Calculation:

⇒ Under-10 students = 24

⇒ Total students = 24 + 8

⇒ Total students = 32

∴ The correct answer is 32.

Given:

Total distance = 560 km

Speed₁ = 40 km/h

Speed₂ = 160 km/h

Total time = 9 hours 30 minutes = 9.5 hours

Let distance travelled at 40 km/h = x km

Formula Used:

Total time = (Distance at 40 ÷ 40) + (Distance at 160 ÷ 160)

Distance at 160 km/h = 560 − x

Calculation:

⇒ $\frac{x}{40} + \frac{560 - x}{160} = 9.5$

⇒ $\frac{x}{40} + \frac{560}{160} - \frac{x}{160} = 9.5$

⇒ $\frac{x}{40} + 3.5 - \frac{x}{160} = 9.5$

⇒ $\frac{x}{40} - \frac{x}{160} = 6$

⇒ $\frac{4x - x}{160} = 6$

⇒ $\frac{3x}{160} = 6$

⇒ $x = \frac{6 \times 160}{3}$

⇒ $x = 320$

∴ The correct answer is 320 km.

Given:

Marked price (MP) = 120 (20% above CP)

Profit percentage = 8%

Discount percentage = x%

Formula Used:

SP = CP × (100 + Profit%) / 100

SP = MP × (100 - Discount%) / 100

Calculation:

⇒ SP = 100 × (100 + 8) / 100

⇒ SP = 100 × 108 / 100

⇒ SP = 108

⇒ 108 = 120 × (100 - x) / 100

⇒ (100 - x) = 108 × 100 / 120

⇒ (100 - x) = 90

⇒ x = 100 - 90

⇒ x = 10

∴ The correct answer is 10.

Given:

Principal (P) doubles itself in 5 years at compound interest (compounded annually)

Formula used:

Amount (A) = P[1 + (R/100)]^T

R = Rate of interest

T = Time period

Calculation:

According to the question:

2P = P[1 + (R/100)]⁵

⇒ 2 = [1 + (R/100)]⁵

⇒ 2^1/5 = 1 + (R/100)   ----(i)

Let the required time period be T years.

⇒ 4P = P[1 + (R/100)]^T   ----(ii)

From (i) and (ii), we get:

4 = [2^1/5]^T

⇒ 4 = 2^T/5

⇒ 2² = 2^T/5

⇒ T/5 = 2

⇒ T = 10

∴ It will become 4 times in 10 years.

Total salary of all = Total salary of technicians + Total salary of remaining employees

Calculation:

⇒ Total salary of 7 technicians = 7 × 24,000

⇒ = 1,68,000

Let the number of remaining employees = x

⇒ Total salary of remaining employees = x × 12,000

⇒ Total salary of all employees = (1,68,000 + 12,000x)

Average salary of all = 18,000

⇒ 18,000 × (7 + x) = 1,68,000 + 12,000x

⇒ 1,26,000 + 18,000x = 1,68,000 + 12,000x

⇒ 18,000x − 12,000x = 1,68,000 − 1,26,000

⇒ 6,000x = 42,000

⇒ x = 42,000 ÷ 6,000

⇒ x = 7

Total number of employees = 7 technicians + 7 remaining employees

⇒ 14

∴ The correct answer is 14 employees.

Work per day = Total work ÷ Time

Y's work = (X + Y) − X

Time = Total work ÷ Y's 1-day work

Calculation:

⇒ Take LCM of 8 and 40 as total work = 40 units

⇒ (X + Y)'s 1-day work = 40 ÷ 8 = 5 units/day

⇒ X's 1-day work = 40 ÷ 40 = 1 unit/day

⇒ Y's 1-day work = 5 − 1 = 4 units/day

⇒ Time taken by Y = 40 ÷ 4

⇒ Time = 10 days

∴ Y alone will complete the work in 10 days.

Given:

Total medals = 85

Ratio = Silver : Gold = a : b

Formula used:

Total medals = k(a + b)
