Answer 1

Answer:

1. The numbers are 96 and 36.

2. Total number of 2 rupee coins = 20

Total number of 5 rupee coins = 16

total number of rupee 10 coins = 8

Step-by-step explanation:

1. Let us take the numbers as 8x and 3x. We know that their sum is 132.

So,

8x + 3x = 132

11x = 32

x = $\frac{132}{11}$

= 12

Therefore, the first number is 8x = 8 × 12 = 96 and the second number is 3x = 3 × 12 = 36

2. Let's take the numbers as 10 × 2x = 20x, 5 × 4x = 20x and 2 × 5x = 10x.

Now, we know that

10x + 20x + 20x = 200

50x = 200

x = $\frac{200}{50}$

x = 4

Therefore, we know that there's totally:

20x = 80 rupees worth of 10 rupee coins.

20x = 80 rupees worth of 5 rupee coins.

10x = 40 rupees worth of 2 rupee coins.

Now,

Total number of 2 rupee coins = 40/2 = 20

Total number of 5 rupee coins = 80/5 = 16

total number of rupee 10 coins = 80/10 = 8

Their ratio now is 8:16:20

When simplified, their ratio is 2:4:5.

I hope this helps!!
