the number of 2 coins.​

Answer 1

Answer:

here your answer.......

Step-by-step explanation:

given ratio of coins 4:6:9.

let the number of 5 rupee coins is 4a

5 × 4a = 20a

similarly 2 rupee coins 6a, 2 × 6a = 12a

and

1 rupee coins 9a, 1 × 9a = 9a

the bag contain total money 410

then,

20a + 12a + 9a = 410

41a = 410

a = 410/41

a = 10

Hence

the number of 5 rupee coins

4a = 4 × 10 = 40 coins,

2 rupee coins 6a = 6 × 10 = 60 coins,

1 rupee coins 9a = 9 × 10 = 90 coins.

therefore the number of Two rupee coins

is 60 coins.

verification:-

Here

5 rupee coins is 40

2 rupee coins is 60

1 rupee coins is 90

so

5 × 40 + 2 × 60 + 1 × 90

200 + 120 + 90

410

Hence verified.
