if the price of a certain computer increased 30 percent from a dollars to 351 dollars, then 2 a =
multiply(divide(351, divide(add(const_100, 30), const_100)), 2)
"before price increase price = a after 30 % price increase price = a + ( 30 / 100 ) * a = 1.3 a = 351 ( given ) i . e . a = 351 / 1.3 = $ 270 i . e . 2 a = 2 * 270 = 540 answer : option a"
