Answer 1

Given:

अपर्णा खाना पकाने के लिए रोजाना 50 मिली तेल का इस्तेमाल करती हैं। 1 लीटर तेल के पैकेट को पूरी तरह से इस्तेमाल करने में कितना समय लगेगा?* 1️⃣ 25 दिन 2️⃣ 10 दिन 3️⃣ 2 दिन 4️⃣ 20 दिन​

Aparna uses 50 ml of oil daily for cooking. How long will it take to completely use a 1 liter oil packet?

* 1️⃣ 25 days 2️ 10 days 3️⃣ 2 days 4️⃣ 20 days​

To find:

How long will it take to completely use a 1 liter oil packet?

Solution:

The quantity of oil Aparna uses for cooking in 1 day = 50 ml

We know,

$\boxed{\bold{1 \:litre = 1000 \:ml}}$

So, we have to find that how many days will it take for Aparna to finish the 1000 ml packet of oil.

Now,

If 50 ml is used in 1 day

Then, 1 ml will be used in = $\frac{1}{50}$ day

∴ 1000 ml will be used in = $\frac{1}{50} \times 1000 = 20 \:days$ ← option (4)

Thus, it will take 20 days to completely use a 1 liter oil packet.
