A) 80
B) 120
C) 100
D) 135
Correct Answer: B
Solution :
Let the number of coins of 50 paise, 25 paise and 10 paise are 2x, 3x and 5x respectively. \[\therefore \] Value of 50 paise coins \[=\frac{2x}{2}=Rs.\,x\] and value of 25 paise coins \[=Rs.\frac{3x}{2}\] and value of 10 paise coins \[=Rs.\frac{5x}{10}=Rs.\frac{x}{2}\] \[\therefore \] \[x+\frac{3x}{4}+\frac{x}{2}=90\] \[\Rightarrow \] \[4x+3x+2x=360\] \[\Rightarrow \] \[x=40\] \[\therefore \] Number of 25 paise coins \[=3\times 40=120\]You need to login to perform this action.
