two numbers are in the ratio of 6 : 8 . if 10 is subtracted from each , the new numbers are in the ratio 16 : 32 . find the smaller number .
"explanation : let the number be 6 x and 8 x . then , ( 6 x – 10 ) / ( 8 x – 10 ) = 1 / 2 2 ( 6 x – 10 ) = ( 8 x – 10 ) 12 x – 20 = 8 x – 10 4 x = 10 x = 2.5 the smaller number = ( 6 x 2.5 ) = 15 answer d"
subtract(multiply(multiply(subtract(multiply(32, 10), multiply(16, 10)), 6), divide(8, 6)), multiply(subtract(multiply(32, 10), multiply(16, 10)), 6))
