उत्तर
Let he required number of cement bags be x.
| Days | Machines | Cement bags |
| 12 | 36 | 7000 |
| 18 | 24 | x |
Number of days more ⇒ More cement bags.
∴ It is direct variation.
∴ The multiplying factor = `18/12`
Number of machines more ⇒ More cement bags.
∴ It is direct variation.
∴ The multiplying factor =`24/36`
∴ x = `7000 xx 18/12 xx 24/36`
`(7000 xx 18 xx 24)/(12 xx 36)`
x = 7000 cement bags
7000 cement bags can be made
