Answers
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
