Answer:

Number of coin Rs 5 = 20

Number of coin Rs 2 = 60

Number of coin Rs 1 = 80

Step-by-step explanation:

Let,

Coin of Rs 5 = x

Coin of Rs 2 = 3x

Total number of coins is 160

So,

Coin of Rs 1 = 160 - (3x + x)

⇒ 160 - 4x

Coin of Rs 1 = 160 - 4x

★ Value of Coins :

Coin of Rs 5 = 5x

Coin of Rs 2 = 6x

Coin of Rs 1 = 160 - 4x

★ According to the question :

Total Rs. 300

⇒ 5x + 6x + (160 - 4x) = 300

⇒ 5x + 6x - 4x = 300 - 160

⇒ 11x - 4x = 140

⇒ 7x = 140

⇒ x = 140 ÷ 7

⇒ x = 20

Coin of Rs 5 = 20

Coin of Rs 2 = 3x

⇒ 3 (20)

⇒ 60

Coin of Rs 2 = 60

Coin of Rs 1 = 160 - 4x

⇒ 160 - 4 (20)

⇒ 160 - 80

⇒ 80

Coin of Rs 1 = 80

Therefore,

Number of coin Rs 5 = 20

Number of coin Rs 2 = 60

Number of coin Rs 1 = 80
