Answer:
no of quarter = 58
Step-by-step explanation:
value of a nickel = 5 cents
value of a quarter = 25 cents
Ravi has total coins = 122
Let Ravi has no. of nickel = x
so no of quarter = 122 - x
worth of nickel = 5x
worth of quarter = 25 ( 122 - x )
Total amount worth = 1770 cent = $ 17.70
5 x + 25 ( 122 - x ) = 1770
5 x - 25 x + 3050 = 1770
-20 x = 1770 - 3050
- 20 x = - 1280
x = 1280 / 20
x = 64
no. of quarter = 122 - x
= 122 - 64
= 58
