Given:

The marked price of a book is ₹900.

The purchase price after two discounts is ₹769.50.

The first discount rate is 5%.

Concept:

Successive discount calculation involves applying each discount one after the other on the reduced price.

Formula Used:

Let the second discount rate be x%.

First discount price = Marked Price × (1 - First Discount Rate)

Second discount price = First Discount Price × (1 - Second Discount Rate)

Calculation:

Let the second discount rate be x.

First discount price:

⇒ ₹900 × (1 - 0.05)

⇒ ₹900 × 0.95

⇒ ₹855

Second discount price:

⇒ ₹855 × (1 - x)

Given second discount price is ₹769.50:

⇒ ₹855 × (1 - x) = ₹769.50

Solve for x:

⇒ 1 - x = 769.50 / 855

⇒ 1 - x = 0.9

⇒ x = 1 - 0.9

⇒ x = 0.1

∴ The second discount rate is 10%.

Formula used:

1. (a³ - b³) = (a - b)³ + 3ab(a -b)
2. (a - b)² = a² - 2ab + b²
3. (a + b)2 = a2 + 2ab +b2
4. (a - b)(a + b) = a2 - b2

Calculation:

Given that

x = and y =

⇒ xy = × = 1 -----(1)

⇒ x - y = -

⇒ x - y =

By using the formula (2), (3) & (4)

⇒ x - y =

⇒ x - y = 2√3 -----(3)

We know that

(x3 - y3) = (x - y)3 + 3xy(x -y)

⇒ (x3 - y3) = (2√3)³ + 3 × 1 (2√3)

⇒ (x3 - y3) = (2√3)3 + 3 × 1 (2√3)

⇒ (x3 - y3) = 8 × 3√3 + 6√3

∴ (x3 - y3) = 30√3

Given:

An inlet pipe can fill an empty tank in 4 1/2hours while an outlet pipe drains a completely filled tank in 7 1/5  hours.

Concept used:

Efficiency = (Total work / Total time taken)

Efficiency = work done in a single day

Calculation:Time taken by A = 9/2 hours

Time taken by B = 36/5

Capacity of tank = LCM(9/2, 36/5) = 36 units

Efficiency of A = 36/(9/2) = 8 units

Efficiency of B = 36/(36/5) = - 5 units

tank filled in 2 hours = 8 - 5 = 3 units

tank filled in 20 hours = 30 units

and

Please note that after 20 hours, the remaining capacity = 6 units

Now in the 21st hour, pipe A will work and fill the tank so no need to add time after that.

Time taken by pipe A to fill 6 units = 6/8 = 3/4 hours

So,
Total time taken = 20 + 3/4 = 20 3/4  hour 

Given:

A is 26° more than its complementary angle.

B is 30° less than its supplementary angle.

Concept used:

Complementary angles are those angles whose sum is 90°

Supplementary angles are those whose sum is 180°

Calculation:

A + A - 26 = 90

⇒ 2A = 116

⇒ A = 58

B + B + 30 = 180

⇒ 2B = 150

⇒ B = 75

So,

A - B

⇒ 58 - 75

⇒ - 17

∴ required value is - 17

Given

Speed of bus without stoppage = 60 km/h

Speed of bus with stoppage = 51 km/h

concept

Time = Distance/ speed of bus without stoppage

1 hour = 60 minutes

calculation

Bus travelled in 1 hour excluding stoppage = 60 km

Bus travelled in 1 hour including stoppage = 51 km

such that bus travelled 9 km less (60 - 51) due to stoppage

Time taken by bus to cover 9 km = 9/60 hours

⇒ (9/60) × 60 minutes

⇒ 9 minutes

∴ Bus stop per hour is 9 minutes.

Given:

Speed during first half of the journey (s) = 24 km/hr.

Speed during second half of the journey (s') = 36 km/hr.

Total time taken for the whole journey = 7 hours 30 minutes = 7.5 hours

Formula used:

Speed = distance / time.

Calculation:

Let the total distance be 2x km.

Speed = distance / time

Time = distance / speed

7.5 = x/24 + x/36

7.5 = (3x + 2x) / 72

5x = 72 × 7.5

x = 540 / 5

x = 108 km.

Total distance travelled = 2x = 2(108) = 216 km.

∴ Total distance he travelled is 216 km.

Given : [{(49 × 12) - (6 ÷ 2)} + (4 - 3)] ÷ 5

So, after interchanging the signs :

⇒[{(49 - 12) + (6 × 2)} ÷ (4 + 3)] × 5

⇒[{37 + 12} ÷ 7] × 5

⇒[49 ÷ 7] × 5

⇒7 × 5

⇒35

Hence, "35" is the correct answer.
