A) 50
B) 100
C) 150
D) 200
Correct Answer: C
Solution :
Let the coins are 25 paise. 10 paise and 5 p? are x, 1x and 3x respectively. \[x\times 0.25+2x\times 0.10+3x\times 0.05=30\] \[\Rightarrow \] \[0.25x+0.20x+0.15x=30\] \[\Rightarrow \] \[0.60x=30\] \[\therefore \] \[x=\frac{30}{0.60}\] \[=50\] \[\therefore \] Required number of 5 paise coins \[=3\times 50\] \[=150\]You need to login to perform this action.
