Answer :
Absolutely, let's go through the problem step-by-step.
(i) Express the above statements in the form of linear equations:
Let's define:
- [tex]\( b \)[/tex] as the cost of the bag.
- [tex]\( u \)[/tex] as the cost of the umbrella.
According to the problem, we have two pieces of information:
1. The total cost of the bag and the umbrella is Rs 1000:
[tex]\[ b + u = 1000 \][/tex]
2. The umbrella is cheaper than the bag by Rs 200:
[tex]\[ b = u + 200 \][/tex]
So, the system of linear equations is:
[tex]\[ \begin{cases} b + u = 1000 \\ b = u + 200 \end{cases} \][/tex]
(ii) Find the cost of the bag and the umbrella:
First, we'll substitute the second equation [tex]\( b = u + 200 \)[/tex] into the first equation [tex]\( b + u = 1000 \)[/tex]:
Substitute [tex]\( b \)[/tex] in [tex]\( b + u = 1000 \)[/tex]:
[tex]\[ (u + 200) + u = 1000 \][/tex]
Simplify the equation:
[tex]\[ u + 200 + u = 1000 \][/tex]
[tex]\[ 2u + 200 = 1000 \][/tex]
Next, we'll solve for [tex]\( u \)[/tex] by isolating [tex]\( u \)[/tex]:
[tex]\[ 2u = 1000 - 200 \][/tex]
[tex]\[ 2u = 800 \][/tex]
[tex]\[ u = 400 \][/tex]
So, the cost of the umbrella [tex]\( u \)[/tex] is Rs 400.
To find the cost of the bag [tex]\( b \)[/tex], we use the equation [tex]\( b = u + 200 \)[/tex]:
[tex]\[ b = 400 + 200 \][/tex]
[tex]\[ b = 600 \][/tex]
Therefore, the cost of the bag [tex]\( b \)[/tex] is Rs 600 and the cost of the umbrella [tex]\( u \)[/tex] is Rs 400.
Conclusion:
- The cost of the bag is Rs 600.
- The cost of the umbrella is Rs 400.

[tex]\[ b = 400 + 200 \][/tex]
[tex]\[ b = 600 \][/tex]
Therefore, the cost of the bag [tex]\( b \)[/tex] is Rs 600 and the cost of the umbrella [tex]\( u \)[/tex] is Rs 400.

- The cost of the bag is Rs 600.
- The cost of the umbrella is Rs 400.
