Answer 1

Your answers:

1st problem answer:

Given :

No. of bags produced last year = 1720 bags.

Increased percentage = 20%

Required to find :

1. No. of more bags going to be obtained
2. Total no. of the bags obtained by the farmer this year.

Solution :

1.

so , In the question it is given that a farmer had obtained 1720 bags last year.

But this year he has an expectation that he/she would receive 20% more no. of bags.

so, to find the no. of more bags he obtained

here we should use a simple trick. Please see the explanation of the trick .

No. of more bags he receives is equal to the given percentage multiplied with no. of bags produced last year divided by 100.

Mathematically it is represented as

$more \: bags = \frac{\%}{100} \times bags \: obtained \: last \: year$

so ,

Now substitute there respective values.

Calculations:

$more \: bags \: = \frac{20}{100} \times 1720 \\ more \: bags \: = \frac{34400}{100} \\ more \: bags \: = 344 \: bags$

Therefore,

No. of more bags he will receive = 344 bags.

2.

similarly ,

Total no. of bags he will receive this year is

no. of bags produced last year + no. of more bags obtained this year.

= 1720 + 344

= 2,064 bags.

Total no. of bags received are 2,064 bags.

2nd problem answer :

Given :

Marked price = Rupees 3600

Selling price = rupees 3312

Required to find:

1. Discount amount
2. Discount percentage

solution :

In the question it is given that a cycle was been marked a price of rupees 3600.

But the retailer sold it for a price of rupees 3312 ( selling price ).

Here we have to find the discount amount.

Generally,

It is very simple to discount amount using a formula .

Discount amount = Marked price - Selling price

( This is read as discount price is equal to Marked price minus selling price )

In mathematically it is shown as

discount = M.P - S.P

here,

M.P refers to Marked price

S.P refers to selling price

Therefore, ( calculations)

discount = 3600 - 3312

= rupees 288.

2.

Now , coming to second part of the question we have to find the discount percentage.

Here,

For finding this discount percentage simply use a formula.

$discount\% = \frac{discount}{marked \: price} \times 100$

(This is read as discount percentage is equal to discount amount by marked price multiplied with 100 )

so,

Let's substitute there respective values

$d\% = \frac{288}{3600} \times 100 \\ d\% = \frac{288}{36} \\ d\% = 8\%$

Therefore on solving further we got,

Discount percentage = 8%

Hence your question are solved.
