Answers
Answer:
In the question it is said that the no of some particular coins are in the ratio= 1:2:3
&
The value of these coins is = Rs 30
Now, lemme make it simple for you guys
It is given that,
Face value of coins= 25p 10p 5p
No of coins = 1: 2 : 3
Value =0.25 0.20 0.15
We got the values by converting the paise into rupees and then multiplying with its respective no of coins
25paise = 25/100 *1=0.25
5 paise = 5/100 *3 = 0.05*3 =0.15
Note - It is very important to convert paisa into rupees because values are measured in terms of rupees only and not in terms of paisa
A/Q
=> 0.25u+0.20 u+0.15u=30
=> 0.60 units = 30
=> 1unit = 30/0.60
=> 1unit = 50
So the number of 5p coins are =50 *3 = 150 coins
