Question

If the cost of a dozens soap is 460.80 , what will be the cost of :
(i) each soap (ii) 15 soaps
(iii) 3 dozen soaps

Answer 1

Cost of dozen soaps $460.80$

Cost of one soap $\frac{460.80}{12}=38.4$

Cost of $15$ soaps $\frac{460.80\times 15}{12}=38.4\times 15=576$

Cost of $3$ dozens $3\times 460.80=1382.4$
