Question

Aravind has piggy bank.it is full of fifty- paise coins. It contains 3 times as many fifty paise coins as one rupee coins. The total amount of the money in the bank is Rs.35. How many coins of each kind are there in the bank?

Answer 1

Answer:

Answer:

      let number of one rupee coins = x

therefore , number of 50 paisa coins = 3x

Total amount of money = Rs 35

therefore ,

   0.5(3x) + 1(x) = 35

.15x +1x= 35

or 25/10x=35

or 25x= 35*10

or 25x =350

or x= 14

Therefore , Number of one Rupee coins = 12

Hence Number of 50 paisa coins = 3*14 = 42

Hope this Helps You :)

Thank You!!! 

Answer 2

let us assume that the number of coins of 1 rupee are x

therefore coins of 50 paisa are 3x

amount of 1 rupee coin = 1×x=100x paisa

amount of 50 paisa coins=50×3x=150 paisa

100x+150x=4500

250x=4500

x=18

hope it helps you
