Given : A man bought two computers for Rs.45000. He sold one at a loss of 5% and the other at a profit of 5% . the selling price of each set is same
To Find : the cost price of each set.
Solution:
CP are 100x & 100y
100x + (5/100)100x = 105x
100y - (5/100)100y = 95y
105x = 95y
=> 21x = 19y
100x + 100y = 45000
=> x + y = 450
x + y = 450
21x = 19y
=> 21x = 19(450 - x)
=> 40x = 19 * 450
=> 4x = 19 * 45
=> 4x * 25 = 19 * 45 * 25
=> 100x = 25 * 19 * 45
=> 100x = 21375 Rs
100x + 100y = 45000
=> 100y = 23625 Rs
Cost price are Rs.23625 and Rs.21375
