Answer 2

Answer:

Step-by-step explanation:

Let the ratio constant be x

therefore, the no. of 1 rupee coins⇒5x

                 the no. of 2 rupee coins ⇒4x

amount in rs 1 coins - Rs 5x

amount in Rs 2 coins - 4x × 2= Rs 8x

total amount⇒ 5x+8x

According to the question,

5x+8x=65

13x=65

x=65/13

x=5

Therefore,no. of 2 rupee coins⇒4x=4×5

                                                   ⇒Rs 20
