Question
"M' sold a watch to 'N' making a
profit of 20%. 'N' then sold it to 'X' at a 10% loss. If 'M' had directly sold the watch to 'X' at a 10% profit instead, he would have earned Rs. 16 more. What was the price at which 'N' purchased the watch from 'M'?Solution
ATQ, Let price of watch for 'M'= 100x Price for N = 120% of 100x = 120x Price for X when N sold the watch to him = 90% of 120x = 108x Price for X when M sold the watch to him = 110% of 100x = 110x ATQ, 110x – 108x = 16 x = 8 Price at which N bought that watch from M = 120x = Rs.960
