ANSWER.....
Mohan has 75 Rupees.
that consists of 25 paise coins and 50 paise coins.
25 paise coins is thrice the Number of 50 coins
25 paise coins be X
50 Paise coins be Y
X = 3 × Y
X/4 + Y/2 = 75
3Y/4 + Y/2 = 75
LCM OF 4 & 2
(3Y + 2Y ) / 4 = 75
5Y = 75×4
5Y = 300
Y= 300 / 5
Y = 60
X = 60 × 3
X = 180
Number of 25 paise coins = 180
Number of 50 paise coins = 60
