Let the cost price of the cycle be Rs. 100x
So, its sale price =Rs.108×[Profit is 8%]
Secondly, when the cost price is 10% less
i.e., when the cost price = Rs. (100x -10x) = Rs. 90x
The profit =12% of Rs. 90x =Rs.(12100)×90x=Rs.108x10
Its sale price =Rs.90+Rs.(10810)=Rs.100810
First sale price - Second sale price = Rs. 36
Rs.108x−Rs.1008x10=Rs.36
Or, (1080x−1008x)10=Rs.36
Or, 72x10=Rs.36
Or, x=5
Cost price of the cycle = Rs. 100x = Rs. 500
