Given : A man sells two watches for Rs. 1820 each
on one he gain 30% and the on the other he loses 30%.
To Find : the total total cost price of the two watches.
Rs.2000
Rs.3640
Rs.4000
Rs.3500
Rs 3000
Solution:
Cost prices of watches are A & B
30 % Gain
= (30/100)A
= 0.3A
A + 0.3A = 1820
=> 1.3A = 1820
=> A = 1400
30% loss
= (30/100)B
= 0.3B
B - 0.3B = 1820
=> 0.7B = 1820
=> B = 2600
Total Cost price = 1400 + 2600 = Rs 4000
total total cost price of the two watches. = Rs 4000
