1. Answer:

   There are 1500 coins of 5 p in the bag.

   Step-by-step-explanation:

   We have given that,

   There are coins of 25 p, 10 p and 5 p in the ratio of 1 : 2 : 3.

   Let the common multiple be x.

   ∴ 25 p coins = x

   10 p coins = 2x

   5p coins = 3x

   From the given condition,

   There are total Rs. 30 in the bag.

   Now, we know that,

   Re. 1 = 100 paise

   ⇒ Rs. 30 = 30 * 100 paise

   ⇒ Rs. 30 = 3000 paise

   ∴ x + 2x + 3x = 3000

   ⇒ 3x + 3x = 3000

   ⇒ 6x = 3000

   ⇒ 3x = 1500 – – – [ Dividing by 2 ]

   ∴ There are 1500 coins of 5 p in the bag.

2. Given :-

   In a bag, there are coins of 25 p, 10 p, and 5 p in the ratio of 1:2:3. If there is Rs. 30 in all

   To Find :-

   Number of 5 p coins

   Solution :-

   We know that

   1 rupees = 100 paise

   30 rupees = 30 × 100 = 3,000 paise

   Let

   Number of 25 paise = y

   Number of 10 paise = 2y

   Number of 5 paise = 3y

   y + 2y + 3y = 3000

   6y = 3000

   y = 3000/6

   y = 500
