12. A can contains a mixture of two liquids A and B is the ratio 7 : 5. When 9 litres of mixture are drawn off and the can is filled with B, the ratio of A and B becomes 7 : 9. How many litres of liquid A was contained by the can initially?

**Answer:**** Option C **

**Explanation:**

Suppose the can initially contains 7x and 5x of mixtures A and B respectively.

Quantity of A in mixture left = (7x-7*9/12 ) Litres = (7x - 21/4) litres.

Quantity of B in mixture left = (5x - 5*9/12) Litres = (5x - 15/4) litres.

[(7x - 21/4)/ (5x-15/4)+9] = 7/9

=> (28x - 21)/(20x + 21) = 7/9

=> 252x - 189 = 140x + 147 => 112x = 336

=> x = 3.

So, can contained 21 litres of A.

14. In how many different ways can the letters of the word 'LEADING' be arranged in such a way that the vowels always come together?

**Answer:**** Option C **

**Explanation:**

The word 'LEADING' has 7 different letters.

When the vowels EAI are always together, they can be supposed to form one letter.

Then, we have to arrange the letters LNDG (EAI).

Now, 5 (4 + 1 = 5) letters can be arranged in 5! = 120 ways.

The vowels (EAI) can be arranged among themselves in 3! = 6 ways.

Required number of ways = (120 x 6) = 720.

15. Sam purchased 20 dozens of toys at the rate of Rs. 375 per dozen. He sold each one of them at the rate of Rs. 33. What was his percentage profit?

**Answer:**** Option D **

**Explanation:**

Cost Price of 1 toy = Rs. (375/12) = Rs. 31.25

Selling Price of 1 toy = Rs. 33

So, Gain = Rs. (33 - 31.25) = Rs. 1.75

Profit % = (1.75/31.25) x 100 % = 28/5 % = 5.6%

16. If the simple interest on a sum of money for 2 years at 5% per annum is Rs. 50, what is the compound interest on the same at the same rate and for the same time?

**Answer:**** Option A **

**Explanation:**

Sum = Rs. (50 * 100)/(5*2) = Rs. 500.

Amount = Rs. [500 * (1 + 5/100)2]

= Rs. (500 * 21/20 * 21/20 )

= Rs. 551.25

C.I. = Rs. (551.25 - 500) = Rs. 51.25
