Answer 2

Answer:

The price of the shirt is 52 rupees

Step-by-step explanation:

Given, a man's coat cost seven times as much as his shirt.

Let,cost of his shirt be x rupees.

So,cost of his coat is 7x rupees.

It is also given,

the bill for the two togather is rs.416

So,

$x + 7x = 416 \\ 8x = 416 \\ x = \frac{416}{8} \\ x = 52$

Therefore price of the shirt is 52 rupees.

This is a problem of Algebra.

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
