Answer 1

Given : The Volume of Shampoo Bottle can Hold : 1 Litre & 140 ml

We know that One Litre is Made up of 1000 ml

⇒ The Volume of Shampoo Bottle can hold : (1000 + 140) = 1140 ml

Given : Radhika uses 95 ml of Shampoo every week.

⇒ The Number of weeks the Shampoo bottle will last is :  $\frac{1140}{95}$

⇒ The Number of weeks the Shampoo bottle will last is : 12
