Answer:-
Let the number of Rs. 1 coins be "x" and 25 P = (Rs. 0.25) coins be "y".
Hence,
Value of Rs. 1 coins = x(1)
→ Value of Rs. 1 coins = x
Value of Rs. 0.25 coins = y (0.25)
→ Value of Rs. 0.25 coins = 0.25y
Given that,
The value of the total number of coins is 6 less than the number of coins.
→ x + 0.25y = (x + y) - 6
→ x - x + 0.25y - y = - 6
→ - 0.75y = - 6
→ y = ( - 6)/ ( - 0.75)
→ y = 8
Hence, there are "8" 25P coins in the purse.
