40 × ? + ( 12 + 8 ) × 3 / 5 = 1212
"explanation : = > 40 × ? + ( 12 + 8 ) × 3 / 5 = 1212 = > 40 × ? = 1212 - ( 12 + 8 ) × 3 / 5 = > 40 × ? = 1212 - 20 × 3 / 5 = > 40 × ? = 1212 - 20 × 3 / 5 = 1200 = > ? = 1200 / 40 = 30 answer : option e"
divide(subtract(1212, multiply(add(12, 8), divide(3, 5))), 40)
