4. Your monthly take up pay of $1804 increased by 6% due to a promotion, but your expenses have changed in certain areas as shown in the table below. DO YOUR SAVINGS INCREASE OR DECREASE AND BY HOW MUCH ?

Answer 1

Answer:

Let the present age of Dilip's son be x. Age of Dilip's son 2 years ago = (x - 2) Age of Dilip 2 years ago = 3(x - 2) Age of Dilip's son after 2 years = (x + 2) Age of Dilip after 2 years = 3(x - 2) + 4 = 3x - 6 + 4 = (3x - 2) Twice the age of Dilip is equal to five times the age of his son. 2(3x - 2) = 5(x + 2) 6x - 4 = 5x + 10 6x - 5x = 10 + 4 x = 14 Present age of Dilip's son is 14 years. Age of Dilip 2 years ago = 3(14 - 2) = 36 years Present age of Dilip = 36 + 2 = 38 years
