Answer:
12 Rs 1 coins
Step-by-step explanation:
Ratio between 1 rupee and 2 rupee coins is 3:2
Let say Rs 1 coin = 3x
then Rs 2 coin = 2x
Then Rs 5 coins = 23 - 3x - 2x = 23 - 5x
Value of coins
= (3x * 1) + (2x * 2) + (23-5x) * 5
= 3x + 4x + 115 - 25x
= 115 - 18x
Value of coins = 43
115 - 18x = 43
=> 18x = 72
=> x = 4
number of Rs 1 coins = 3x = 3*4 = 12
1 2 & 5
12 , 8 & 3 Coins
12 + 16 + 15 = 43
