Question:

A bag contains 1 rupee, 50-paise and 25-paise coins in the ratio 5 : 6 : 7. If the total amount is ₹390, find the number of 25-paise coins

Options:

280

200

240

260

Correct Answer:

280

Explanation:

                            Total amount = 390

                            1 Rs.           50 P            25 P

Number    →            5                6                 7

In Rupees →            5x             \(\frac{6}{2}\) = 3x      \(\frac{7}{4}\) = 1.75x

 

So, (5 + 3 + 1.75)x = 390 (given)

                     9.75x = 390

                           x = 40

 

No. of 25 P coins = 7 × 40 = 280
