Sunita has Rs.390in Rs. 5 and Rs. 2 coins .If the number of Rs 2 coins is four times that of Rs. 5 coins, tFind the number of each type of coins .​

Answer 1

Answer:

Let the number of 5 rupees coins be x

∴ No. of 4 ₹2 coins = 4x

Total money = ₹390

Amount of ₹5 coin = x × 5

                               =5x

Amount of ₹2 coin = 4x × 2

                               = 8x

A.T.Q

⇒5x+8x = 390

⇒13x = 390

⇒x = 390/13

⇒x = 30

∴ No. of ₹5 coins = x = 30

  No. of ₹2 coins = 4x = 120

Answer 2

Answer:

The number of Rs. 5 coins is = 30

And the number of Rs. 2 coins is = 120

Step-by-step explanation:

Let the number of Rs.5 coins is = x

Hence the number of Rs.2 coins is = 4x

According to question

5*(x) + 2*(4x) = 390

5x + 8x = 390

13x = 390

x = 30

Hence the number of Rs. 5 coins is = x = 30

And the number of Rs. 2 coins is = 4x = 120
