2. The total population of a village is 5000. The number of males and females increases by 10% and 15% respectively and consequently the population of the village becomes 5600. what was the number of males in the village ?
Answer: Option B
Explanation:Lets Assume males and females as x and y respectively.
So total Population (x+y)=5000 -----------(1)
Incresed by 10% and 15%
so (x+(10x/100))+(y+15y/100)=5600
=> 110x/100+115y/100=5600
By Solving eq. (1) & (2)
y=2000 x=3000 (i.e Male population)

4. 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.
