Given that She has 7 more than 2 coins than 50 paise coins = 2(x + 7.)
Given that the value of all the coins = 76.50
= > 0.5x + 2(x + 7) = 76.50
= > 0.5x + 2x + 14 = 76.50
= > 2.5x = 62.5
= > x = 25.
x + 7 = 25 + 7
= 32.
The number of 50 paise coins = 25 and number of 2 rupee coins = 32.
Hope this helps!
