Answer:
Step-by-step explanation:
Let the no. of 50 p coins = x
no. of 25 p coins = 2x
Value of 50 p = 50*x = 50x
Value of 25 p = 25*2x = 50x
34 rs = 3400 p
Equation = 50x + 50x = 3400
Solve :
100x = 3400
x = 3400/100
x = 34
Therefore, no. of 50 p coins = 34
no. of 25 p coins = 34*2 = 68
Check :
50 p coins = 34*50 = 1700
25 p coins = 68*25 = 1700
1700 + 1700 = 3400
Hence, proved.
