Question

Raj had 10 coins of Rs5 & 20 of Rs10.He exchanged 5 Rs10 coins with 5 Rs10 notes,out of which 2 were fake.Find the total valid money Raj has now?

• A. Rs 220
• B. Rs 230
• C. Rs 250
• D. Rs 200

Answer 1

The correct option is B Rs 230

Amount with Raj:

10 coins of Rs.5 = $10\times 5=Rs.50$

And 20 coins of Rs.10 = $20\times 10=Rs.200$

Total amount with Raj = 50 + 200 = Rs.250

Raj exchanged 5 Rs.10 coins with 5 Rs.10 notes

So, he exchanged Rs 50

2 Rs 10 notes were fake = Rs.20

Hence, total valid money with Raj now = 250 - 20 = Rs.230

Answer: B Rs.230
