Question

In a bag, the number of one rupee coins is three times the number of two rupees coins.If the worth of the coins is Rs. 1200,Find the number of 1 rupee coins​

Answer 1

Answer:

Let two rupees coins are x in numbers.

So, one rupee coins are 3x in numbers. According to question,

1(3x) + 2(x) = 1200

⇒ 3x + 2x = 1200

⇒ 5x = 1200

⇒ x = 1200/5 24

Thus, 240 × 24 – 72 coins are of one rupee coins.

Answer 2

Answer:

let the number of two rupee coin is x

so the number of one rupee coin is 3x

the amount of two rupee coin is 2.x Rs

the amount of one rupee coin is 3x Rs

then,

2.x+3x=1200

=> 5x=1200

=> x=1200/5=240

number of one rupee coin is 3.240=720
