1. By selling a bicycle for Rs. 2,850, a shopkeeper gains 14%. If the profit is reduced to 8%, then the selling price will be:

Solution:
Let Cost Price was X.
X + 14% of X = 2850
X + 14X100 = 2850
X + 0.14X = 2850
1.14X = 2850
X = 2500.
So, Cost Price = Rs. 2500.
Now, Selling Price When profit remains at 8%,
= 2500 + 8% of 2500
= Rs. 2700.

Short-Cut
CP of bicycle = 100114 × 2850 = Rs. 2500
SP for a profit of 8% = 108100 × 2500 = Rs. 2700
