Question

A shopkeeper sells 5 candies for Rs. 350. If he increases the price of each candy by Rs. 10 then what will be the new cost of one candy and how much will the 5 candies cost after the cost is updated?

• A. Rs. 80, Rs. 360
• B. Rs. 60, Rs. 355
• C. Rs. 75, Rs. 375
• D. Rs. 80, Rs. 400

Answer 1

The correct option is D Rs. 80, Rs. 400

Initial cost of 5 candies = Rs. 350
Initial cost of 1 candy = $\frac{350}{5}$ = Rs. 70
Updated cost of candy = 70 + 10 = Rs.80
Cost of 5 candies after increase in cost = 80 $\times$ 5 = Rs. 400
