Given: ₹4,800

Concept:

Percentage of a number can be calculated by multiplying

the number with the percentage and dividing by 100.

Steps:

⇒ 25% of ₹4,800 = ₹4,800 × 25/100 = ₹1,200

⇒ 15% of ₹1,200 = ₹1,200 × 15/100 = ₹180

⇒ 10% of ₹180 = ₹180 × 10/100 = ₹18

Therefore, 10% of 15% of 25% of ₹4,800 is ₹18.

Given:

2% of x = 24.

Formula Used:

To find x:

x = 

Calculation:

2% = 2/100.

Given, 2% of x = 24.

⇒ (2/100) × x = 24

⇒ x = 24 ÷ (2/100)

⇒ x = 24 × (100/2)

⇒ x = 24 × 50

⇒ x = 1200

The value of x is 1200.

Given:

2% of 50% of a number is what percentage of that number?

Formula used:

If x% of y% of a number is taken, the result can be written as:

(x/100) × (y/100) × Number = Result

To find the percentage of the number, use:

(Result / Number) × 100

Calculation:

Let the number be N.

⇒ 2% of 50% of N = (2/100) × (50/100) × N

⇒ = (2 × 50) / (100 × 100) × N

⇒ = (100 / 10000) × N

⇒ = (1 / 100) × N

Now, to find what percentage this is of N:

⇒ ((1 / 100) × N / N) × 100

⇒ (1 / 100) × 100

⇒ = 1 %

∴ The correct answer is option (1).

Given:

50% of 9642 + 40% of 2255 + 12.5% of 384

Concept used:

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

Calculation:

According to the question,

50% of 9642 + 40% of 2255 + 12.5% of 384

⇒ (1/2) × 9642 + (2/5) × 2255 + (1/8) × 384

⇒ 4821 + 902 + 48

⇒ 5771

∴ 5771

Given:

Percentage = 25%

Value = 8000

Formula used:

Value = (Percentage × Total) / 100

Calculation:

Value = (25 × 8000) / 100

Value = 200000 / 100

Value = 2000

∴ 25% of 8000 is: 2000

Given:

P is 40% less than Q.

Shortcut Trick

40% = 2/5

So, Q is 2/(5-2) × 100 = 2/3 × 100 = 66.66% more than P.

∴ Q is 66.66% more than P.

Calculation:

Let, Q = 100y

So, P = 100y × (100 - 40)/100 = 100y × 60/100 = 60y

Now,

(Q – P)/P × 100 = 40y/60y × 100  = 66.66%

∴ Q is 66.66% more than P.

Additional Information

If A is 20% less than B,

So,

B is 20/(100 - 20) × 100 = 20/80 × 100 = 25% more than A

Similarly,

If B is 25% more than A,

So,

A is 25/(100 + 25) × 100 = 25/125 × 100 = 20% less than B.

Given:

200% of k - (k + 2)% of 50 = k

Formula used:

A% of B = (A/100) × B

Calculation:

⇒ 200% of k - (k + 2)% of 50 = k

⇒ (200/100) × k - (k + 2)/100 × 50 = k

⇒ 2k - 0.5(k + 2) = k

⇒ 2k - 0.5k - 1 = k

⇒ 1.5k - 1 = k

⇒ 1.5k - k = 1

⇒ 0.5k = 1

⇒ k = 1/0.5 = 2

Formula Used:

X% = X/100

Calculation:

(120% of 675) + 92 = (? % of 1240) + 716

⇒ × 675 + 92 = × 1240 + 716

⇒ 810 + 92 = 12.4 × ? + 716

⇒ 902 - 716 = 12.4 × ?

⇒ 186/12.4 = ? = 15

∴ The correct answer is 15

Suppose the initial price = Rs. x per kg

Suppose the family spends Rs. 100 initially and this comes down to Rs. 93;

∴ [93/0.75x] – [100/x] = 12

⇒ 124/x – 100/x = 12

⇒ 24/x = 12

⇒ x = 2

∴ Increased consumption = 100/2 + 12 = 62 kg

Formula Used:

X% = X/100

Calculation:

⇒ 980 of 12% = 

⇒ 227 of 30% = 

⇒ 117.6 - = 68.1

⇒ 117.6 - 68.1 = 

⇒  = ? = 11

∴ The correct answer is 11.

Solution:

75% of 480 + 48% of 750

⇒ (75/100) × 480 + (48/100) × 750

⇒ (3/4) × 480 + (12/25) × 750

⇒ 3 × 120 + 12 × 30

⇒ 360 + 360

⇒ 720

Given:

80% of A = 50% of B and B = x% of A

Calculation:

80% of A = 50% of B.

⇒  A =  B

⇒ 8A = 5B

⇒ 

∴ B =  = 160 

So, the value of x is 160.

Given:

20% of (x + y) = 25% of (x - y)

Formula used:

Percentage = (Obtained value/Total value) × 100

Calculation:

20% of (x + y) = 25% of (x - y)

⇒ 20(x + y) = 25(x - y)

⇒ 20x + 20y = 25x - 25y

⇒ 20y + 25y = 25x - 20x

⇒ 45y = 5x

⇒ x = 9y

Now, Percentage = (Obtained value/Total value) × 100

⇒ (x/y) × 100

⇒ (9y/y) × 100 

⇒ 900%

Calculation:

p + p% of 99 = 99 + 99% of p

⇒ p + (p × 99)/100 = 99 + (99 × p)/100

⇒ p = 99

Now, (p + 51)% of 928 + 72

⇒ (99 + 51)% of 928 + 72

⇒ 150% of 928 +72

⇒ 1392 + 72

⇒ 1464

∴ Correct answer is 1464.
