Answer 2

Answer:

The cost of one trouser is Rs.414

Step-by-step explanation:

Given:

• Cost of five trousers exceeds the cost of eight shirts by Rs 150.
• The cost of one shirt is Rs.240

To find: The cost of one trouser.​

Solution

Let

The cost of 1 shirt be x

The cost of 1 trouser be y

The linear equation is

5y - 8x = 150

Given that

cost of 1 shirt = Rs.240

x = 240

⇒ 5y - 8x = 150

⇒ 5y - 8 (240) = 150

⇒5y - 1920 = 150

⇒5y = 1920 + 150

⇒5y = 2070

⇒ y = 2070 / 5

⇒ y  = 414

Cost of one trouser = Rs. 414

Final answer:

The cost of one trouser is Rs.414
