A) 60
B) 120
C) 150
D) 180​

Answer 1

Answer:(a)60

Step-by-step explanation:

let the number of one rupe coin contain in the box in the ratio 2x

similarly 50 paise contain 3x and

25 paise contain 4x

according to the question

2x+3x+4x=180

=>9x =180

=>x=180/9

=>X=20

SO , The number of one rupe contain 2x = 2*20=40

Number of 5o paise contain 3x=3*20=60

And number of 25 paise contain 4x =4*20=80

Answer 2

Answer:

120

Step-by-step explanation:

Let the number of coins = x

So, the number of Rs. 1 coins = 2x

Number of 50 paise coins = 3x

Number of 25 paise coins = 4x

According to question,

1(2x) + 1/2(3x) + 1/4(4x) = 180

2x + 3(x)/2 + x = 180

3x + 3(x)/2 =180

6 + 3(x)/2 = 180

9(x)/2 = 180

x = 180 × 2 / 9

x = 40

The number of 50 paise coins are 3x = 3(40) = 120

∴ The number of 50 paise coins are 120.
