Write the given information as an equation and find its solution.
Sakshi prepared some jam at home and filled it in bottles. After giving away 7 of the bottles to her friends, she still has 12 for herself. How many bottles had she made in all? If she filled 250g of jam in each bottle, what was the total weight of the jam she made?
उत्तर
Let the total number of jam bottles made by Sakshi be x.
According to the given condition,
Total number of jam bottles made by Sakshi − Number of jam bottles given to her friends = Number of jam bottles left with Sakshi
∴ x − 7 = 12
⇒ x − 7 + 7 = 12 + 7 (Add 7 to both sides)
⇒ x + 0 = 19
⇒ x = 19
So, the total number of jam bottles made by Sakshi is 19.
Weight of jam in each bottle = 250 g
∴ Total weight of the jam
= Weight of jam in each bottle × Number of bottles
= 250 g × 19
= 4750 g
= 4.75 kg (1 kg = 1000 g)
Thus, the total weight of the jam made by Sakshi is 4750 g or 4.75 kg.
