A shopkeeper sold a mobile for Rs.14400 and incurred a profit. If he sold the mobile for Rs.11400, he incurred a loss which is equal to 25% of the amount of profit incurred, then find the cost price of the mobile?
A. Rs.12000
B. Rs.16000
C. Rs.15000
D. Rs.10000
E. None of these
Sol:
Answer: A
Let the cost price of the mobile = x
(14400 – x) * 25/100 = x – 11400
14400 * 1/4 – x/4 = x – 11400
3600 + 11400 = x + x/4
4x + x = 15000 * 4
x = 15000 * 4/5
x = 12000
