Question

(2)
In a bag, number of one rupee coin is three times than two rupees coin. If there
are only Rs 150 in this bag, then find out the number of both the coins.​

Answer 1

Answer:

=> No. of 1 rupee coin = 90

=> No. of 2 rupees coin = 30

Step-by-step explanation:

Let the no. of two rupees coin = x

So, no. of one rupee coin = 3 × x = 3x

A.T.Q

=> 1(3x)+2(x) = 150

=> 1 × 3x + 2 × x = 150

=> 3x + 2x = 150

=> 5x = 150

=> x = 150

5

=> x = 30 .

Answer 2

Answer:

Let the no of Rs 1 and Rs 2 coin be x and y.

x=3y-------(1)

A/q

x(1)+y(2)=150

3y+2y=150(using 1)

5y=150

y=30

No of Rs 1 coin=3(30)=90

No of Rs 2 coin=30
