Question

If 18 dolls cost € 630, how many dolls can be bought for € 455?​

Answer 1

Answer:

If more dolls are bought the cost will also be more. Therefore it’s directly proportional.

Let the number of dolls be x,

18/630 = x/455

630 × x = 18 × 455

630x = 8190

x = 8190/630

x = 13

Therefore, 13 balls can be brought for ₹ 455.
