Son - 30, daughter - 20.

What is the working(logic)
Son - x, daughter - y
y=x-10 and 2y=x+10
By simplifying this equation we get x-30,y-20.
In eq 1 it should be y+10 = x-10 and
In eq 2 it should be 2(y-10) = x + 10

A man phoned his daughter to ask her to buy a few things he needed for a trip. He told her she would find enough dollar bills for the purchases in an envelope on his desk. She found the envelope with 98 written on it.

In a store she bought \$90 worth of things, but when it was time to pay she not only didn’t have \$8 left over but she was short.

By how much was she short of cash, and why?
