Question 6 : A, B, C and D share a loot. A gets a% of the total. B gets b% of the remaining (after A has taken his share). C gets c% of the remaining and D gets the rest. D gets a% less than what A gets, B and C get equal amounts. b = 2a.

1. What percentage of what A got did C get?

2. If the total amount is equal to Rs. 1000, what is the difference between what A got and what D got?

Let total amount = T

A would have got T * a. After A takes his share, there would be T (1 - a) left

B would have got T (1 - a) * b

C would have got T (1 - a)(1 - b) * c

D would have got T (1 - a) (1 - b) (1 - c)

D gets a % less than what A gets, or, T *a (1 - a) = T(1 - a) (1 - b) (1 - c), or

a = (1 - b)(1 - c) ------(1)

B and C get the same amounts, or (1 - a) * b = (1 - a) * (1 - b) * c, or b = (1 - b) c, or, b = c - cb, or

b = \\frac{c}{c}\\) + 1 ------(2)

b = 2a -------(3)

Substituting, Equations (2) in and (3) in (1), we get

\\frac{c}{2(c + 1)}\\) = \\frac{1 - c}{c + 1}\\), or c = 2 - 2c, or c = \\frac{2}{3}\\)

b = \\frac{c}{c + 1}\\) = \\frac{2}{5}\\) , a = \\frac{1}{5}\\)

A gets 20% of the loot, B gets 40% of the remaining 80%, or 32% of the loot. C gets 66.6% of 48%, or 32% of the overall loot. And D gets the final 16% of the overall amount (20% lesser than A's share).

The question is **" 1. What percentage of what A got did C get? "**

A got 20% of overall, C got 32% of overall. Or, C got 160% of A

**" 2. If the total amount is equal to Rs. 1000, what is the difference between what A got and what D got? "**

A would have got Rs. 200, D Rs. 160. A would have got Rs. 40 more than D.

Choice A is the correct answer.
