Answer» Correct Answer - Option 3 : 150

Concept:

Suppose a set of n objects has n1 of one kind of object, n2 of a second kind, n3 of a third kind, and so on with n = n1 + n2 + n3 +...+ nk then the number of distinguishable permutations of the n objects is = \(\frac{{{\rm{n}}!}}{{{{\rm{n}}_1}! \times {{\rm{n}}_2}! \times {{\rm{n}}_3}! \ldots \ldots \ldots {{\rm{n}}_{\rm{k}}}!}}\)

Addition and Multiplication principal:

If there are m ways to choose an object one and n ways to choose an object two then the number of ways of selecting objects one and two are given by m × n.
If there are m ways to choose an object one and n ways to choose an object two then the number of ways of selecting objects one or two is given by m + n.

Calculation:

Total no. of toys = 5
Total no. of children = 3
Each should get one toy
Selection can be done as follows: (2, 2, 1) or (1, 1, 3)

= ⁵C₂ × ³C₂ × ¹C₁ × \(\frac {3!}{2!}\) + ⁵C₁ × ⁴C₁ × ³C₃× \(\frac {3!}{2!}\)

= (10 × 3 × 1 × 3) + (5 × 4 × 1 × 3)

If the cost price of 5 articles is equal to the selling price of 8 articles, then find the profit or loss percentage.1. 25.5% loss2. 35% profit3. 37.5% loss4. 40% profit

Answer» Correct Answer - Option 3 : 37.5% loss

Given:

5CP = 8SP

Formula used:

Loss% = (CP – SP)/CP × 100

Calculation:

5CP = 8SP

⇒ CP/SP = 8/5

⇒ SP/CP = 5/8

⇒ 1 – SP/CP = 1 – 5/8 [Subtract 1 both sides]

⇒ (CP – SP)/CP = (8 – 5)/8

⇒ (CP – SP)/CP × 100 = 3/8 × 100

⇒ Loss% = 37.5% [Loss% = (CP – SP)/CP × 100]

∴ The loss% is 37.5%.

A dealer sold a motor cycle at 10% discount and he gains 26% . If he gives 26% discount find profit or loss percentage.1. 4.22. 3.6%3. 4.5%4. 8.1%5. 5%

Answer» Correct Answer - Option 2 : 3.6%

Given:

Profit = 26%

Discount = 10%

Case 2 discount: 26%

Formula used:

Selling price = Marked price (100 - discount 1)/100

Calculation:

Let CP be 100

SP = 126

⇒126 = MP × 90/100

MP = 140

According to question

If discount is 26%

SP in case 2

⇒ SP = 140(100 - 26)/100

⇒ SP 140 × 74/100

⇒ SP = 103.6

⇒ Now profit = 3.6

CP = 100

⇒ Profit % = (3.6/100) × 100

∴ Profit % is 3.6.

Calculation

Let the CP of 1 g = x

Given SP of 1 kg = 1.2 CP = 1200x

But the CP of what he is selling = 750x

His Profit = 1200x – 750x = 450x

∴ Total Profit % = (450x/750x) × 100 = 60%

1130.	A man finds that CP of 275 articles is equal to SP of 250 articles. Find the profit percent.1. 10%2. 25%3. 12%4. 8%
Answer» Correct Answer - Option 1 : 10% Given: SP of 250 articles = CP of 275 articles Formula used: P = S.P. – C.P. L = C.P. – S.P. P% = (P/C.P.) × 100 L% = (L/C.P.) × 100 Where, P → Profit L → Loss SP → Selling price CP → Cost price Calculations: Let the CP of 1 article be Rs.y and its SP be Rs.x. So the SP of 250 articles = 250x And the CP of 275 articles = 275y According to the question, 250x = 275y ⇒ x ∶ y = 11 ∶ 10 Now let x and y be 11k and 10k respectively. Since x > y So P = 11k – 10k = k P% = (P/CP) × 100 ⇒ P% = (k/10k) × 100 = 10% ∴ The required Profit% is 10%.

A man finds that CP of 275 articles is equal to SP of 250 articles. Find the profit percent.1. 10%2. 25%3. 12%4. 8%

Answer» Correct Answer - Option 1 : 10%

Given:

SP of 250 articles = CP of 275 articles

Formula used:

P = S.P. – C.P.

L = C.P. – S.P.

P% = (P/C.P.) × 100

L% = (L/C.P.) × 100

Where,

P → Profit

L → Loss

SP → Selling price

CP → Cost price

Calculations:

Let the CP of 1 article be Rs.y and its SP be Rs.x.

So the SP of 250 articles = 250x

And the CP of 275 articles = 275y

According to the question,

250x = 275y

⇒ x ∶ y = 11 ∶ 10

Now let x and y be 11k and 10k respectively.

Since x > y

So P = 11k – 10k = k

P% = (P/CP) × 100

⇒ P% = (k/10k) × 100 = 10%

∴ The required Profit% is 10%.

Answer» Correct Answer - Option 4 : 55%

Given:

Shalu bought a tea set = 3/10^th of MP

SP = 50% more than CP

Calculation:

⇒ CP = 3/10 × 100 = Rs. 30

⇒ SP = 30 × 150/100 = Rs. 45

⇒ discount = Rs (100 - 45) = Rs. 55

⇒ discount% = 55/100 × 100% = 55%

∴ The discount percent is 55%.

A toy seller sells his toy at successive discount of 37.5% and 12.5% respectively. Still he gains 5% profit. Find the ratio of MP & CP 1. 15 :72.2 : 13. 48 : 254. 24 : 255. 6 : 13

Answer» Correct Answer - Option 3 : 48 : 25

Given:

Profit% = 5%

Discount 1 = 37.5% Discount 2 = 12.5

To find: MP: CP

Formula used:

Selling price = Marked price (100 - discount 1)/100 × (100 - discount 2)/100

Calculation:

Let CP = 100 there is a profit of 5% on CP that is 105

Hence SP = 105

105 = MP [(100 - 37.5) / 100 × (100 - 12.5) / 100]

105 = MP 62.5 / 100 × 87.5 / 100

105 = MP 5/8 × 7/8

MP = 192

MP : CP = 192 : 100

⇒ MP : CP = 48 : 25

Answer» Correct Answer - Option 5 : 1286.40

GIVEN:

⇒ Discount % = 27.27% = 3/11.

⇒ Profit = 12.5% = 1/8

⇒ The difference of Cost price and Selling price = Rs. 160.80

FORMULA USED:

⇒ C.P = {100/(100 + gain %)] × S.P

⇒ S.P – C.P = Gain

CALCULATION:

⇒ Let cost price = Rs. x

⇒ Profit = 12.5%

⇒ Selling price = x × (112.5/100)

⇒ S.P = 1.125x

⇒ Discount = 27.27%

⇒ Selling price = Marked price × (72.73/100)

⇒ 1.125x = Marked price × (72.73/100)

⇒ Marked price = 1.54x

⇒ Now, Gain = S.P – C.P

⇒ 1.125x – 1x = Rs. 160.80

⇒ 0.125x = Rs. 160.80

⇒ x = Rs. 1286.40

1136.	Look at leaves of the same plant on the shady side and compare it with the leaves on the sunny side. Or, compare the potted plants kept in the sunlight with those in the shade. Which of them has leaves that are darker green? Why?
Answer» Light is a limiting factor for photosynthesis. Leaves get lesser light for photosynthesis when they are in shade. Therefore, the leaves or plants in shade perform lesser photosynthesis as compared to the leaves or plants kept in sunlight. In order to increase the rate of photosynthesis, the leaves present in shade have more chlorophyll pigments. This increase in chlorophyll content increases the amount of light absorbed by the leaves, which in turn increases the rate of photosynthesis. Therefore, the leaves or plants in shade are greener than the leaves or plants kept in the sun.
