In a bag, there are coins of 25 p, 10 p and 5 p in the ratio of 1 : 2 : 3. If there is Rs. 30 in all, how many 5 p coins are there?

100

150

200

Answer : Option C

Explanation :

Let the number of 25 p, 10 p and 5 p coins be x, 2x, 3x respectively.

Then, sum of their values = Rs.[ $\frac { 25X } { 100 }$ + $\frac { 10 *2X } { 100 }$ + $\frac {5 *3X } { 100 }$ ] =Rs. $\frac {60X } { 100 }$

$\frac {60X } { 100 }$ =30 x = $\frac { 30*100 } { 60}$ =50

Hence, the number of 5 p coins = (3 x 50) = 150.
