A man bought two
bikes at equal cost price. He sold one bike at a profit of 14% and sold the
other bike at Rs 4290 more than the cost price. The overall
profit he had on these two bikes is 20%. Find the cost price of each bike?

Answer :

CP of two bikes = 200x Rs. Total profit = 20% = SP = 240x 
Now on one bike, profit = 14% = SP = 114x 
On other bike, SP = 100x + 4290 Rs 
Equating both ==> 114x + 100x + 4290 = 240x
Finding x = 165. And CP of bike = 16500 Rs
