Question

Pls help me with this question.

Answer 1

Step-by-step explanation:

Total amount in the bag = Rs. 30=3000 paise

Let the number of 50 paise coins be x

Then the number of 25 paise coins =4x

Now, according to the question

25(4x)+50x=3000

100x+50x=3000

150x=3000

x=

150

3000

x=20

4x=80

Therefore, number of 50 paise coins =20

Number of 25 paise coins =80

Answer 2

Answer:

The number of 50p coins is 100 and the number of 25p coins is 600.

Step-by-step explanation:

Let's assume that, the number of 50p coins is x.

According to the problem, the number of 25p coins is 6x.

Also, $Rs. \frac{x}{2} + Rs. \frac{6x}{4} = Rs. 200$  [since every pair of 50p coins make a rupee

                                                 and every four 25p coins make a rupee]

$=>\frac{x}{2} + \frac{6x}{4} = 200$

$=>2x + 6x = 800$  [multiplying both sides by 4]

$=>8x = 800$

$=>x = \frac{800}{8} = 100$

$=>6x = (6).(100) = 600$

The number of 50p coins is 100 and the number of 25p coins is 600.
