Question

a toy was sold at a gain of 15% . had it been sold for Rs 27 or more , the gain would have been 18% . find the cost price of toy

Answer 1

Let cost price be x
profit = 15x/100
If it was sold for Rs. 27 more, profit=18x/100
18x/100-15x/100=27
3x/100=27
3x=27*100
x=27*100/3
x=9*100
x=900
HOPE IT HELPS YOU.
