Answer 1

there are 14 one ruppee coins and 21 fifty paise coins

Answer 2

Answer:

One rupee coins=14

50 paise coins =42.

Step-by-step explanation:

Let us assume that in the bank there are p one-rupee coins and q fifty paise coins.

Then by the condition is given, the total amount in the bank is given by  

p+ q/2 =35 ....... (1)

Again, the bank contains 3 times as many 50 paise coins as one rupee coins.

Hence, q=3p..... (2)

Now, solving equations (1) and (2) we get,

p +3p/2 =35, ⇒ p=14.  

Again, from equation (2), we get, q= 3p=3×14 =42.

Therefore, the number of one rupee coin is 14 and that of 50 paise coin is 42. (Answer)
