A) 700
B) 720
C) 668
D) 672
Correct Answer: B
Solution :
If Ratio of 50p, 25p and 10p coins = 5 : 9 : 4 Then, Ratio of 50p, 25p and 10p in rupees \[=\frac{5}{2}:\frac{9}{4}:\frac{4}{10}\] \[=50:45:8\] Now, \[50x+45x+8x=206\] \[103x=206\] \[x=2\] Now, Total number of coins \[=50\times 2\times 2+45\times 2\times 4+8\times 2\times 10\] \[=200+360+160\] \[=720\]You need to login to perform this action.
