Answer 1

Answer:

The  total amount is Rs. 72

Step-by-step explanation:

Let the common ratio is x

Therefore,

Value of Rs. 1 coins = 2x

Number of Rs. 1 coins = 2x/1 = 2x

Value of Rs. 2 coins = 5x

Number of Rs. 2 coins = 5x/2 = 2.5x

Value of Rs. 5 coins = 5x

Number of Rs. 5 coins = 5x/5 = x

Total number of coins = 33

or, 2x+2.5x+x = 33

or, 5.5x = 33

⇒ x = 33/5.5 = 6

The total amount = 2x + 5x + 5x = 12x = 12 × 6 = 72 Rs.

Therefore total amount is Rs. 72
