If 18 Dolls Cost Rs.630, How Many Dolls Can Be Bought For Rs.455?

Cost of 18 dolls = Rs. 630

Cost of 1 doll = Rs.{35 210 630/18 6}

Let no. of dolls which can be bought is Rs. 455 be x

Acc. to problem

(Cost of 1 doll)(No of dolls) = Total cost

35x = 455

x = 455/35

x = 13

So, 13 dolls can be bought.

Hope it helps !!! ☺

 13 dolls

as this is the case of direct proportion :

x1/y1 = x2/y2

18/630 = x2/455

18 * 455 = 630 * x
x= 18 * 455/630 = 13 dolls

hope this helps
