a student multiplied a number by 3 / 5 instead of 5 / 3 , what is the percentage error in the calculation ?
"let the number be x . then , ideally he should have multiplied by x by 5 / 3 . hence correct result was . by mistake he multiplied x by 3 / 5 . hence the result with error = then , error = error % = = 64 % answer : b"
multiply(divide(subtract(divide(5, 3), divide(3, 5)), divide(5, 3)), const_100)
