a) 2 ¾ litres
b) 1 ¼ litres
c) 1 ¾ litres
d) 2 ¼ litres

Answer 1

Answer:

Hence, option (b) $1\frac{1}{4}$ litre is correct.

Step-by-step explanation:

Given : Total milk in the fridge = $2$ litre

          Milk used by Mrs. Bhole = $\frac{3}{4}$ litre

To find : How much milk is left in the fridge after that?

Solution :

• It is given that total milk in the fridge = $2$ litre

                        Milk used by Mrs. Bhole = $\frac{3}{4}$ litre

• We have to find the amount of milk left in the fridge after the usage.
• We know that, $1$ litre = $1000$ ml
• Now, Amount of milk left in the fridge = $2-\frac{3}{4}$

                                                             = $\frac{2*4-3}{4}$

                                                             = $\frac{8-3}{4}$

                                                             = $\frac{5}{4}$

                                                             = $1\frac{1}{4}$ litre

• ∴ The amount of milk left in the fridge after the usage of Mrs. Bhole = $1\frac{1}{4}$ litre

• Hence, option (b) $1\frac{1}{4}$ litre is correct.  

Answer 2

Answer:

Option b) 1¼ litres

Step-by-step explanation:

Milk in fridge in morning = 2litres = 2000ml

Milk used by Mrs. Bhole in Afternoon = ¾ litres = 0.750ml

Milk left in fridge = 2000 - 0.750 = 1.250ml = 1¼ litres
