Step-by-step explanation:
it will be 2500 for 1 set of radio set. so it will be 1250 for the cost of each radio.
Answer: 2000 radios were sold at a 12℅.
3000 radio were sold at a 8%
Step-by-step explanation:
Let x represent the cost of the radio8% loss that was sold at a loss of 12%.
Let y represent the cost of the radio that was sold at a gain of 8%.
A man bought two radio sets for Rs 5000 . He sold one at a loss of 12% and the other at gain of 8%. This means that
x + y = 5000
Profit made on the first radio is 0.12x
Profit made on the second radio is 0.08x.
He neither gained nor loss in the transaction. This means that
0.12x = 0.08y - - - - - - - - - -- - -1
Substituting x = 5000 - y into equation 1, it becomes
0.12(5000 - y) = 0.08y
600 - 0.12y = 0.08y
0.08y + 0.12y = 600
0.2y = 600
y = 600/0.2
y = 3000
x = 5000 - y = 5000 - 3000
x = 2000
