Question

If the cost of a dozen soaps is Rs. 153.60, what will be the cost of 15 such soaps?

Answer 1

We know that 1 dozen = 12
Since, cost of 12 soaps = Rs. 153.60

Therefore, cost of 1 soap = `153.60/12` = Rs. 12.80

Therefore, cost of 15 soaps = Rs. 12.80 × 15 = Rs. 192.

Thus, cost of 15 soaps is Rs. 192.
