1
Shyam and Ram entered into a partnership with investment in the ratio 3 : 2 respectively. Among them, Ram is the working partner for which he gets 10% of the profit and Shyam is the sleeping partner. If at the end of one year they earned a profit of Rs. 75000 out of which 5% goes to the charity. Find the share of Ram in the profit.
» Explain it
D
 Amount goes to charity = 5 × 75000 = Rs. 3750 100

Amount goes to Ram as a working partner

 = 10 × 75000 = Rs. 7500 100

Remaining amount = Rs. (75000 – 3750 – 7500) = Rs. 63750

 Share of Ram in the remaining profit = 2 × 63750 = Rs. 25500 5

Total share of Ram = Rs. (7500 + 25500) = Rs. 33000

Hence, option D is correct.

2
An alloy of aluminium, copper and Iron contains 85% aluminium, 8% copper and 7% iron. A second alloy of aluminium and iron melted with the first and the mixture then contains 75% aluminium, 5% copper and 20% iron. Find the percentage of aluminium in the second alloy.
» Explain it
B
Let x and y be the mass of 1st alloy and 2nd alloy.

 aluminium in the 1st alloy = 85x 100

 copper in the 1st alloy = 8x 100

 iron in the 1st alloy = 7x 100

According to question, for copper

 8x 100 × 100 = 5 x + y

8x = 5x + 5y

3x = 5y

 x = 5 y 3

x = 5 and y = 3

Let p = percentage of aluminium in the 2nd alloy

According to question,

 5 × 85 + 3 × p = (5 + 3) × 75 100 100 100

3p = 175

 p = 175 = 58.33% 3

Hence, option (B) is correct.

3
The simple interest on a certain sum for 2 years at a certain rate of interest is Rs.2000 and compound interest on the same sum, same time and same rate of interest is Rs.2050. Then find the ratio between CI for 2 years and CI for 3 years?
» Explain it
A
SI for 2 years = Rs.2000

SI for 1 year = Rs.1000

In the 2nd year Rs.50 is added in CI which is 5% of 1000

Hence, R = 5%

⇒ 5% = 1000

⇒ 100% = 20000

Sum = Rs.20000

 CI for 3 years = 20000 ( 105 ) 3 – 20000 100

⇒ 23152.5 – 20000

⇒ 3152.5

Required ratio = 2050 : 3152.5

⇒ 20500 : 31525

⇒ 820 : 1261

Hence, option A is correct.

4
If four coins are tossed together, what is the probability of at least getting 2 heads?
» Explain it
B
P (getting at least 2 heads) = 1 – P (getting no head or exactly one head)

 P (getting no head) = P (getting all tails) = 1 16

Getting exactly one head means 3 tails and 1 head in any order and the total occurrences here are
 = 4! = 4 3!

 = 4 = 1 16 4

Hence, P(getting at least 2 heads)
 = 1 – ( 1 + 1 ) = 11 16 4 16

Hence, option B is correct.

5
A fruit vendor sells apples and oranges and gets equal revenue from each. He gets a profit of 20% on each apple and a profit of 25% on each orange. If the ratio of the number of oranges sold to the number of apples sold is 3 : 2, what is the ratio of the cost price of an orange to that of an apple?
» Explain it
B
Let P be revenue from each apple and orange.

 Cost of apples = P × 100 = 5P 120 6

 Cost of oranges = P × 100 = 4P 125 5

Let the number of apples sold by the fruit vendor be 2n, then the number of oranges sold would be 3n.

 Cost price of each apple = 1 × 5P = 5P 2n 6 12n

 Cost price of each orange = 1 × 4P = 4P 3n 5 15n

 Therefore, reqd. ratio = 4P : 5P = 16 : 25 15n 12n

Hence, option B is correct.
