Question
If the average cost price of 25 identical shirts decreases
by Rs. 5 after replacing one shirt with a new shirt that costs Rs. 100, what was the original cost price of the replaced shirt?Solution
ATQ;
Let the cost price of each shirt be Rs. 'x'.
So, cost price of 25 shirts = Rs. 25x
ATQ:
(25x - x + 100) ÷ 25 = x - 5
Or, 24x + 100 = 25x - 125
Or, x = 225
So, the cost price of the shirt that was removed is Rs. 225.
