Answer:
40
Step-by-step explanation:
Let the number of 20cent coins be 'x'
Then, 10cent coins are 'x + 12'
Total amount = $5.4 = 540 cents
20(x) + 10(x + 12) = 540
20x + 10x + 120 = 540
30x = 540 - 120
30x = 420
x = 420/30
x = 14 (14 20cent coins)
x + 12 = 26 (26 10cent coins)
Total coins = 14 + 26 = 40
