# If selling price is doubled then profit become tripled. Therefore profit percent is :

(a) 66 2/3

(b) 100

(c) 105 1/3

(d) 120

**Answer: (b) 100**

**Solution:-**

Let the CP be 100,

According to question,

Then, SP = 200

Profit = (SP-CP)/100 x 100

= (200-100)/100 x 100

= (100/100) x 100

= 100

Therefore the profit is 100

Hence, the correct answer is option (b) 100.
