Question

A vegetable seller had 25kg of onions He sold 20 kg 250 g How much onions are left with him ?

Answer 1

4 kg 750 gm of onions are left with the vegetable seller.

------------------------------------------------------------------------------------------------

Let's understand a few concepts:

The conversion rate of grams to kilograms is:

$\boxed{\bold{1 \:gram = \frac{1}{1000}\:kilogram = 0.001\:kilogram }}$

-----------------------------------------------------------------------------------------------

Let's solve the given problem:

We will convert 20 kg 250 g into kilograms by using the following conversion rate:

20 kg 250 gm = 20 kg + $\frac{250}{1000} \:kg$ = 20 kg + 0.25 kg = 20.25 kg

We are given,

The quantity of onions the vegetable seller had = 25 kg

The quantity of onions he sold = 20.25 kg

Therefore,

The quantity of onions left with him after selling 20.25 kg from 25 kg is,

= 25 kg - 20.25 kg

= 4.75 kg

= 4 kg + 0.75 kg

= 4 kg + (0.75 × 1000) gm

= 4 kg 750 gm

Thus, 4 kg 750 gms of onions are left with him.

Answer 2

Given,

A vegetable seller had 25kg of onions and he sold 20 kg 250 g.

To Find,

Onions left with him =?

Solution,

We can solve the question as follows:

It is given that the shopkeeper has 25 kg of onions and he sold 20 kg 250g.

Now,

We will convert grams into kilograms so that the physical quantities are in the same S.I. unit.

We know,

$1 g = 0.001 kg$        (Since 1 kg = 1000 grams)

We will multiply 250g with 0.001 to convert it to kilograms,

$250 g = 250*0.001 kg$

        $= 0.25 kg$

Now, the total amount of onions sold will be equal to 20kg and 0.25 kg.

Amount of onions sold $= 20kg + 0.25 kg$

                                        $=20.25 kg$

Amount of onions left with him = Total onions - onions sold

                                                     $= 25kg - 20.25 kg$

                                                       $= 4.75 kg$

Hence, the vegetable seller has 4.75 kg of onions left.
