Am I completely retarded or is this answer wrong? It was one of the questions on the GMAT prep CAT. I got a 53Q, by the way on the prep CAT
"In May Mrs. Lee's earnings were 60 percent of the Lee family's total income. In June Mrs. Lee earned 20 percent more then in May. If the rest of the family's income was the same both months, then in June, Mrs. Lee's earnings were approximately what percent of the Lee family's total income."
Why is the answer not 72? This problem is driving me nuts.
