Question

The cost of one dozen dolls is 120 find the cost of such 10 dolls

Answer 1

Given,

cost of one dozen dolls = 120

To find:

cost of 10 dolls

Sol:

we know that,

cost of 1 doll = cost of 1 dozen dolls/ 12 (since 1 dozen =12 dolls)

=120/12

=10

also we know ,

the cost of 10 such dolls= cost of 1 doll× 10

=10×10

=100

Hence, the cost of ten dolls is ₹100 (hundred rupees) when the cost of one dozen dolls is 120
