The respective ratio of the heights of cylinders A and B is 2 : 1. What is the respective ratio of volumes of cylinders A and B?**- 25 :42
- 23 : 42
- 32 : 49
- 30 : 49
- 36 : 49

Answer: Option C32:49V= 4_{A}:V_{B }= πr_{A}^{2}h_{A}: πr_{B}^{2}h_{B}^{2}x2 : 7^{2}x1 = 32:49per formula, ( a + b - c )^{2}= a^{2}+ b^{2}+ c^{2}+ 2ab – 2bc – 2ac

Therefore, ( 12 + 16 - 22 )^{2}= 36

**At present, Aanshi is five years younger to Binny. Binny’s age twenty- years hence will be equal to twice of Aanshi’s age five years ago. What will be Binny’s age eight year hence?**- 42 years
- 35 years
- 30 years
- 48 years
- None of these

Answer: Option DLet age of Aanshi be A, Bunny be B.According to equation, A= B-5Also, B+20 = 2(B-10)Solving these we get, B= 40. So 8 years hence his age will be 48 years.**A number is such that when it is multiplied by 6, it gives another number which is s more than 168 as the original number itself is less than 168.

**Percent profit earned when an article is sold for Rs. 558/- is double the percent profit earned when the same article is sold for Rs. 504/-. If the marked price of the article is 30% above the cost price, what is the marked price of the article?**- Rs. 585/-
- Rs. 595/-
- Rs. 624/-
- Rs. 590/-
- Rs. 546/-

Answer: Option ALet Percent profit be P558 = (1+ 2P/100)CP504 = (1+P/100)CPSolving these equations we get, CP=Rs.450, p=12%Now, MP=1.3*450 = Rs.585/-.**Dhruva gave 35% of her monthly salary to her mother. From the remaining salary, she paid 18% towards rent and 42% she kept aside for her monthly expenses. The remaining amount she kept in bank account.

- Rs. 75,000
- Rs. 64,000
- Rs. 76,000
- Rs. 72,000

Answer: Option ELet ‘x’ be the monthly salary, then

(65/100 × 40/100)x + 35/100x = 43920

Solving, X= 72000**18 litres of pure water was added to a vessel containing 80 litres of pure milk. 49 litres of the resultant mixture was then sold and some more quantity of pure milk and pure water was added to the vessel in the respective ratio of 2 : 1. If the resultant respective ratio of milk and water in the vessel was 4 : 1, what was the quantity of pure milk added in the vessel? (in litres)**- 4
- 8
- 10
- 12
- 2

Answer: Option E80(M) + 18(W) = 9849 liters sold => 49 is left40(M) + 9(W)Let x be the quantity of pure milk addedGiven, (40 + 2x)/(9 + x) = 4/1Solving, x = 2**There are two motor cycles (A & B) of equal cost price. Motorcycle A was sold at a profit of 14% and motorcycle B was sold for Rs. 4,290/- more than its cost price. The net profit earned after selling both the motor cycles (A & B) is 20%. What is the cost price of each motorcycle?**- Rs. 16,500/-
- Rs. 16,000/-
- Rs. 15,500/-
- Rs. 71,500/-
- Rs. 17,000/-

Answer: Option A

Let the cost price of each motorcycle be Rs. ‘A’. So SP of A = 1.14A and SP of B = A + 4290. Total CP = 2A. As net profit is given to be 20% on both the motorcycles, so we can form the equation as (2.14A + 4290 - 2A)/2A = 20%. Solving it further, we get (0.14A + 4290)5 = 2A. Solving this equation, we get value of A as 16,500**A bag contains 3 white balls and 2 black balls. Another bag contains 2 white and 4 black balls. A bag and a ball are picked at random.
