Answer:
Coins of 5 rupees=23 coins
Coins of 2 rupees=115 coins
Step-by-step explanation:
Let the 2 rupees coins be '5x'.
So, coins of rupees 5 be 'x'.
Total sum of money given in question is 345.
Value of 2 rupees coins= 2×5x.
= 10x
Value of rupees 5 coins = 5×x
= 5x
According to question:
10x+5x = 345
15x = 345
x = 345÷15
x = 23
So, No. of rupees 5 coins = x = 23 coins..
No. of rupees 2 coins = 5x = 115 coins..
Hope this answer helps you!!!
