Answer: 50p = 14
25p = 16
Step-by-step explanation:
Total no. coins = 30
Let no. of 50p coins = x
So, no. of 25p coins = 30 - x
₹11 = 11 × 100
= 1100p
Now, 50x + 25 (30 - x) = 1100
50x + 750 - 25x = 1100
50x - 25x = 1100 - 750
25x = 350
x = 350/25
x = 14
Therefore, no. of 50p coins = x = 14
No. of 25p coins = 30 - x = 30 - 14 = 16
