Answer 2

Answer:

3.89 Kgs

Step-by-step explanation:

Given :

The cost of 1 kg of apple is Rs 180

To find :

apple to  be purchased at Rs 700

Solution :

Here, it is given that 1 kg of apple costs Rs. 180

We know that,

$\boxed{\mathrm{Cost\ of\ apples = No.\ of\ kgs\ \times \ Cost\ per\ kg }}$

So,

As, Cost of apples = Rs. 700 and cost per kg = 180

Substituting in the above formula, we get,

$\implies \mathrm{700 = No.\ of\ kgs\ \times 180}$

$\implies \mathrm{No.\ of\ kgs = \dfrac{700}{180}}$

$\implies \mathrm{No.\ of\ kgs = \dfrac{70\not{0}}{18\not{0}}}$

$\implies \mathrm{No.\ of\ kgs = \dfrac{70}{18}}$

Dividing by 2

$\implies \mathrm{No.\ of\ kgs = \dfrac{35}{9}}$

$\implies \mathrm{No.\ of\ kgs = 3.888...}$

$\implies \mathrm{No.\ of\ kgs = 3.8\dot8}$

$\implies \mathrm{No.\ of\ kgs \approx 3.89}$

So, it is approximately, 3.89 kgs
