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 $=3\times 50$ $=150$
