In May Mrs Lee's earnings were 60 percent of Lees familys total income. In June Mrs Lee earned 20 percent more than in May. If the rest of the familys income was same both months, in June, Lees earning were approximately what percent of Lee's family's total income ?

These problems are best solved by assuming numbers

Let Lee family's income be 100
Lee earns 60 and rest earns 40
Now a hike of 20% means 60*1.2 = 72
Hence Lee earns 72 and family earns 40
Total earning is 112.

Hence 72/112*100 =64.28
Hence A

Thanks,
