Answer 1

Answer:

please mark me brainlist

Explanation:

1 Dozen = Generally 12 Pieces

Now answering the question -

36 Dozens = ₹720

18 Bananas as pieces how much?

Let’s first convert 36 Dozens into Pieces as it will make the solution easy to understand as the question asked is in pieces!

So 36 x 12 (As 12 Pieces make a Dozen)

= 432 Pieces

Now let us know the Price per piece of Banana

720/432 Total Price Divided by 36 Dozens which is 432 Pieces

720/432 = ₹1.66666666666 |Price Per Piece|

(Now that’s Something :p)

So now that we know the Price per Piece it’s very easy to know the price of 18 Pieces…. Just Multiply

Final Answer - 18 x 1.66666666666

= 29.9999999 [₹30] Round Figure!

18 Bananas cost ₹30 making a 0.1 Profit :P

Answer 2

Explanation:

We have given that cost of 1 dozen banana is 36 rupees

we know that

1 dozen= 12 price

So

1 dozen banana=12 bananas

So cost of 1 banana =

$36 \div 12 = 3 \\ in \: the \: same \: way \\ cost \: of \: 5 \: bananas = 3 \times 5 = 15$

So from this question you need to keep 2 things in mind.

1. While finding the value of 1 peice or 1 thing from many things we do divide
2. While finding multiple quantities from 1 peice or thing we multiply
