उत्तर

Let the required number of days be x.

Soaps Hours Days
9600 15 6
14400 (15 + 3) = 18 x

To produce more soaps more days required.

∴ It is direct proportion

∴ Multiplying factor = `14400/9600`

If more hours spend, less days required.

∴ It is indirect proportion

∴ Multiplying factor = `15/18`

∴ x = `6 xx 14400/9600 xx 15/18`

`(6 xx 14400 xx 15)/(9600 xx 18)`

x = `15/2`

`15/2` days will be needed.
