the total of 324 of 20 paise and 25 paise make a sum of rs. 71. the no of 20 paise coins is
divide(subtract(multiply(324, 25), multiply(71, const_100)), subtract(25, 20))
"explanation : let the number of 20 paise coins be x . then the no of 25 paise coins = ( 324 - x ) . 0.20 * ( x ) + 0.25 ( 324 - x ) = 71 = > x = 200 . . answer : d ) 200"
