A, B and C invest in a business. B invests Rs. 5000 more than A and C invests Rs. 5000 more than B. 4/9th of the total profit goes to C. Find the total capital invested in the business.

   A.) Rs. 10,000/-
   B.) Rs. 15,000/-
   C.) Rs. 25,000/-
   D.) Rs. 45,000/-

Answer: Option 'D'

Let the amount of money invested by A be Rs. X
A : B : C = x : x+5000 : x+10000 
C's share = (x + 10000)/(3x+15000) = 4/9
Solving the equation, 
x = Rs. 10000/- 
3x + 15000 = Rs. 45000/-

Answer: Option 'C'

Amount of milk after 2 operations = 10[1 - (1/10)]2 = 10 × (9/10) × (9/10) = 8.1 litres
% of milk = (8.1/10)×100 = 81%

Charan is an much younger than Raju as he is older than Tharun. If the sum of the ages of Raju and Tharun is 50 years, what is definitely the difference between Raju and Charan's age?

   A.) 4 years
   B.) 5 years
   C.) 3 years
   D.) Data inadequate

Answer: Option 'D'

Given that
1. The difference of age between Raju and Charan = The difference of age between Charan and Tharun.
2. Sum of age of Raju and Tharun is 50 i.e (Raju + Tharun) = 50
Question : Raju - Charan = ?
Solution : 
Raju - Charan  = Charan - Tharun
(Raju + Tharun) = 2Charan 
Now given that, (Raju + Tharun) = 50
So, 50 = 2Charan and therefore Charan = 25.
The question is (Raju - Charan) = ?
Here we know the value (age) of Charan(25), but we don't know the age of Raju.
Therefore, (Raju - Charan) cannot be determined
