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 !!! ☺
