Question
A gave 60% of the amount he had to B. B gave 3/5th of
what he received from A to C. After paying Rs. 220 to the taxi driver out of the amount he gets from B, C is now left with Rs. 1400. How much amount did A have?Solution
Let A’s amount be x. C now having the amount of Rs. 1400, => [x × (60/100) × (3/5)] – 220 = 1400 => x × (60/100) × (3/5) = 1620 => x = 1620/0.36 => x = 4500 A initially having an amount of Rs. 4500.
