Question

13. There are some 50 p coins and 3 1 coins in a bag. If the coins are equal in number and total
amount in the bag is * 300, then find the number of 50 p and = 1 coins in the bag.

Answer 1

Answer:

n = 200.

Step-by-step explanation:

let the number of 50 paisa coin = n

let the number of 1 rupee coin = n

50 paisa = x

1 rupee = y

now,

nx + ny = 300

n ( x + y ) = 300

n ( y/2 + y ) = 300

n ( 3y/2) = 300 ( as x = y/2)

n = 300 × 2/3 ( putting y = 1 )

n = 200.

Answer 2

Answer:

Let No. of coins be x

We are given, x + x/2 = 300

= 3x/2 = 300

so, x = 200

So, there are 200 50p coins as well as 200 1 rupee coins.
