The policeman runs at the rate of 20 km/hr

And thief runs at the speed of 15 km/hr

Formula used:

Distance = speed x time

Calculation:

Relative speed = (20 - 15)km/hr = 5 km/hr

Time = distance/ relative speed

= 0.350/5

= 0.07 h

= 4.2 minutes

= 4 minutes 12 seconds

Shortcut Trick

Ratio of efficiency for P, Q, and R = (1/10) : (1/20) : (1/60)

Multiplying by LCM 60, Efficiency ratio = 6 : 3 : 1

Combined Efficiency = 6 + 3 + 1 = 10 units/day

Total Work = 60 units

Time taken = 60 ÷ 10 = 6 days

∴ The correct answer is 6 days.

Alternate Method

Given:

Time taken by P = 10 days

Time taken by Q = 20 days

Time taken by R = 60 days

Formula Used:

Efficiency = Total Work ÷ Time Taken

Calculations:

⇒ Combined efficiency of P, Q and R = 6 + 3 + 1

⇒ Combined efficiency = 10 units/day

⇒ Time taken to complete the job together = Total Work ÷ Combined Efficiency

⇒ Time taken = 60 ÷ 10

⇒ Time taken = 6 days

∴ The correct answer is 6 days.

= 50

No. of students who got B grade 

= 5

Percentage 

=  (No. of students who got B grade/total no. of students) × 100

=  (5/50) × 100

= 10%

Hence, The Required value is 10%.

Given:

 \(\left( {2x - \frac{1}{{4x}}} \right) \)  = 8

Formula used:

a³ - b³ = (a - b)³ + 3ab(a - b)

Calculations:

According to the question,

 \(\left( {8{x^3} - \frac{1}{{64{x^3}}}} \right)\)

= (2x)³ - (1/4x)³

= (2x - 1/4x)³ + 3(2x)(1/4x)(2x - 1/4x)

= 8³ + (3/2)(8)

= 512 + 12

= 524

Hence, The Required value is 524.

Given:

The diameter of ball is 14 cm.

Formula used:

Surface area = 4πr²

Calculations:

Given:

Ramesh bought a mobile phone at 25% discount on the marked price. Had he bought it at 33% discount, he would have saved Rs. 640.

Calculations:

According to question,

(33 - 25)% of x = 640

⇒ 8 % of x = 640

⇒ 0.08x = 640

⇒ x = 640/0.08

⇒ x = 8000

Now, The Cost price 

= 75% of 8000

= 3/4 × 8000

= 6000

Hence, The required value is Rs. 6000.

Given : 

cosec θ + cot θ = 2/5

Formula used :

cosec²θ - cot²θ = (cosec θ + cot θ)(cosec θ - cot θ) = 1 

Calculations :

cosec θ + cot θ = 2/5     ....(1)

cosec θ - cot θ = 5/2    ....(2)

Solving equation 1 and 2 , we get 

cosec θ = 29/20

⇒ sinθ = 20/29          (sin θ = (1/cosec θ)

∴ sin θ is equal to 20/29.

Given:

Diameter of 20 cm then, height = 8 cm.

= πr²h 

= π × (10)²× 8 

= 800π

So, Volume = 800π cm3

∴ Volume of the cylinder is 800π cm³.

Given:

Down payment = Rs.5,000

Formula:

Let P = Principal, R = Rate of interest and N = time

Compound interest = P(1 + R/100) n - P

Calculation:

Amount to be paid in installments = 25000 - 5000 = Rs.20000

Let each installment be of Rs.a

⇒ 20000 = a/(1 + 25/100) + a/(1 + 25/100) 2 + a/(1 + 25/100) 3

⇒ 20000 = 4a/5 + 16a/25 + 64a/125

⇒ 20000 = 244a/125

⇒ a = 20000 × 125/244

⇒ a = 10245.90

∴ Amount of each installment is Rs.10245.90.

Given:

First increase in salary = 10%

Second increase in salary = 5%

Formula used:

Shortcut Trick

Ratio of Amount to Principal = 3 : 2

Interest for 2 years = 3 − 2 = 1 unit

Interest for 1 year = 1 ÷ 2 = 0.5 units

Rate % = (Interest per year ÷ Principal) × 100

Rate % = (0.5 ÷ 2) × 100 = 25%

∴ The correct answer is 25 Percent p.a.

Alternate Method

Given:

Time (T) = 2 years

Amount (A) = 3/2 × Principal (P)

Formula Used:

Simple Interest (SI) = (P × R × T) ÷ 100

Amount (A) = P + SI

Calculations:

⇒ SI = A − P

⇒ SI = (3/2)P − P = (1/2)P

⇒ (1/2)P = (P × R × 2) ÷ 100

⇒ 1/2 = 2R ÷ 100

⇒ 100 = 4R

⇒ R = 100 ÷ 4 = 25%

∴ The correct answer is 25 Percent p.a.

Additional Information

Simple Interest vs Compound Interest

In Simple Interest, the interest is calculated only on the Principal amount, whereas in Compound Interest, interest is calculated on the Principal plus accumulated interest.

Rate of Interest Formula

R = (SI × 100) ÷ (P × T). This formula is derived directly from the standard Simple Interest equation.

Effective Rate

The Effective Rate for SI is simply R × T. For example, 25% for 2 years results in a total interest of 50% of the Principal.

Given:

In the given figure, diameter AB and chord CD of a circle meet at P. PT is a tangent to the circle at T. If CD = 7.8 cm, PD = 5 cm, PB = 4 cm.

Formula used:

PB × PA = PD × PC

Calculations:

Let AB be x.

Now, According to concept, we have:

PB × PA = PD × PC

⇒ 4(4 + x) = 5(5 + 7.8)

⇒ 16 + 4x = 25 + 39

⇒ 4x = 64 - 16

⇒ x = 48/4 = 12

Hence, The Required value of AB is 12 cm.

Given:

The cost price and the selling price of an item are in the ratio 20 : 17.

Concept used :

loss percentage= (CP - SP)/CP × 100

Calculations:

According to question,

loss percentage

= \(\rm\frac{\frac{CP}{SP} - 1}{\frac{CP}{SP}} \times 100\) 

= \(\rm\frac{\frac{20}{17} - 1}{\frac{20}{17}} \times 100\)

= \(\rm\frac{\frac{3}{17}}{\frac{20}{17}} \times 100\)

= \(\rm\frac{3}{20} \times 100\)

= 3 × 5

= 15

Hence, The Required Percentage value is 15%.

Given:

\(\frac{3}{7}, + ,\frac{7}{9}, \times ,\frac{3}{7} \div \frac{3}{{21}} - \frac{7}{3}\)

= \(\frac{3}{7}, + ,\frac{7}{9}, \times ,\frac{3}{7} × \frac{21}{{3}} - \frac{7}{3}\)

= \(\frac{3}{7}, + ,\frac{7}{3} - \frac{7}{3}\)

= \(\frac{3}{7}\)

Hence, The Required value is \(\frac{3}{7}\).

Given:

2m + 8w = 5 days

3m + 4w = 6 days

Formula used:

Total work = Efficiency × days 

Calculations:

⇒ (2m + 8w)5 = (3m + 4w)6

⇒ 10m + 40w = 18m + 24w

⇒ 16w = 8m

⇒ m/w = 2/1

⇒ Total work = (2 × 2 + 8 × 1) × 5

⇒ Total work = 12 × 5 = 60

Time taken by 1m and 2 w = 60/(1 × 2 + 2 × 1)

⇒ 15 days

∴ Time taken by 1 man and 2 woman is 15 days.

Given:

The floor of a room is 8 m 96 cm in length and 6 m 72 cm in breadth.

Calculations:

Length of floor 

= 8 m + 96 cm

= (800 + 96)cm

= 896 cm

Breadth of floor

= 672 cm

To get minimum no. of squares 

= HCF(896, 672)

= 224

No. of squares

= (896 × 672)/(224 × 224)

= 12

Hence, The Required value is 12.

Given:

p + q + r = 9,  and pq + qr + rp = 26

Formula used:

a³ + b³ + c3 - 3abc = (a + b + c){a2 + b2 + c2 -(ab + bc + ca)}

(a + b + c)² = a² + b² + c² + 2(ab + bc + ac) 

Calculation:

According to the question

p3 + q3 = 91, q3 + r3 = 72 and r3 + p3 = 35

Adding all 3 results, we get, 

⇒ 2(p3 + q3 + r3) = 198

⇒ (p3 + q3 + r3) = 198/2 = 99

Using the 2^nd  formula, we get, 

⇒ 9² = p² + q² + r² + 2(pq + qr + rp)

⇒ 81 = p2 + q2 + r2 + 2(26)

⇒  p2 + q2 + r2 = 81 - 52 = 29

Now using the 1^st formula, we get,

⇒ 99 - 3(pqr) = 9 {29 - 26}

⇒ 99 - 3(pqr) = 9 × 3

⇒ 99 - 27 = 3(pqr)

⇒ 72/3 = 24

∴ The value of pqr is 24.
