Answer 1

$\huge\boxed{\fcolorbox{white}{pink}{Answer:-}}$

50 paise = 0.5 Rs

25 paise = 0.25 Rs

• Let the common multiple be x

• Therefore, number of 1 Rs , 50 paise and 25 paise coins are 4x , 5x and 6x respectively.

• According to the given condition,

• 4x + 5x + 6x = 120

•                15x = 120

•                    x = 8

• Thus , the number of 25 paise coins = 6x

•                                                              = 6 x 8

•                                                              =  48 coins
