If 18 dolls cost ₹630, how many dolls can be bought for ₹455
plz help me​

Answer 1

Answer:

If more dolls are bought the cost will also be more. Therefore it's directly proportional. ∴ 13 dolls can be bought for ₹455.

Answer 2

Cost of 18 dolls=Rs.630

Cost of 1 doll=18630=35rupees.

According to the problem,

(cost of 1 doll)(Number of dolls)=Total cost

⇒35x=455

⇒x=35455=13

So,13 dolls can be bought.
