A man has a certain number of one rupee and 10 paise coins. He observes that if the rupees were turned into 10 paise coins and vice-versa, he would have Rs.1.80 less. Again if the rupees were converted into 50 paise coins and the 10 paise coins into 20 paise coins, he would have Rs.5 less. How much amount does he have?

1) Rs.12
2) Rs.12.80
3) Rs.13
4) Rs.10

Read Solution (Total 1)

Rs 13.
he has 12 coins of Rs 1 and 10 coins of 10 paisa.
If he has x coins of 1 Rupee and y coins of 10 paisa, then
90x-90y=180
x-y=2

also 50x-10y=500
5x-y=50

solving, x=12,y=10.
total money = 1*12+0.1*10=13 Rs.
