Question

A house wife has 5l of cooking oil. she uses1/20 l of cooking oil each day. how many days will the cooking oil last.​

Answer 1

Answer:

Step-by-step explanation:

Litres of cooking oil with the family = 5 litres

This is the initial reserve oil of the family.

The family consumes 1.25 litres of oil during the whole month in activities such as cooking and heating.

Thus the remaining oil with the family after all their consumption will be 5-1.25=3.75 litres

The remaining oil with family =3.75 litres

Answer 2

Answer:

20 days

Step-by-step explanation:

Total oil available = 5 liters

Total oil in ml = 5000ml

Oil used per day = 1/20

1/20 of 5000 =

$5000 \times \frac{1}{20}$

$\frac{5000}{20} \times 1$

= 250 ml

Oil used per day = 250ml = 0.25 liters

Days the oil will last = 5000ml ÷ 250ml

= 20

Hence the oil will last 20 days if 1/20 of 5 litres oil is used everyday
