1. A stool costs 360 rupees. What is the total cost of 2 chairs and 3 tables?

2. There were 3 times as many bugs sitting on a tree as there were crows. If the number of bugs is 10 more than the number of crows, then how many crows were sitting in the tree?



Answer :

Certainly! Let's tackle each part of the problem step-by-step:

### Part 1: Cost of 2 Chairs and 3 Tables

Given:
- The cost of one stool is 360 rupees. (However, we’re talking about chairs and tables, so this is just a reference and not directly useful here.)
- We need to find the total cost of 2 chairs and 3 tables.

Unfortunately, we don't have the cost of one chair or one table specified. However, if we did have that information, we could set up the equation like this:

Let:
- [tex]\( C \)[/tex] be the cost of one chair
- [tex]\( T \)[/tex] be the cost of one table

The total cost would be computed as:
[tex]\[ \text{Total Cost} = 2 \times C + 3 \times T \][/tex]

### Part 2: Number of Crows and Bugs on a Tree

Given:
- The number of bugs is 3 times the number of crows.
- The number of bugs is also 10 more than the number of crows.

Let:
- [tex]\( c \)[/tex] be the number of crows
- The number of bugs would then be [tex]\( 3c \)[/tex]

We know that the number of bugs is also 10 more than the number of crows. Therefore, we can set up this equation:
[tex]\[ 3c = c + 10 \][/tex]

Now, let's solve for [tex]\( c \)[/tex]:

Subtract [tex]\( c \)[/tex] from both sides:
[tex]\[ 3c - c = c + 10 - c \][/tex]
[tex]\[ 2c = 10 \][/tex]

Divide both sides by 2:
[tex]\[ c = 5 \][/tex]

Therefore, the number of crows on the tree is 5.

### Summary:

1. Total cost of 2 chairs and 3 tables: To determine this, you would need the specific costs of one chair and one table.
2. Number of crows on the tree: 5 crows
