Question

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?

• A. 50
• B. 100
• C. 150
• D. 200

Answer 1

The correct option is C 150

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

Then, sum of their values = Rs. $(\frac{25x}{100}+\frac{10x2x}{100}+\frac{5x3x}{100})=Rs\frac{60x}{100}$

$\therefore \frac{60x}{100}=30\iff =\frac{30x100}{60}$ = 50

Hence, the number of 5 p coins = $(3\times 50)=150$
