priya and her father differ in their ages by 31 years . after 8 years . if the sum of their ages will be 69 , their present ages are
a 11 , 42 let the age of priya = x years then , the age of her father = ( x + 31 ) years atq , ( x + 8 ) + ( x + 31 + 8 ) = 69 2 x + 47 = 69 2 x = 69 – 47 = 22 x = 11 the age of priya = 11 years the age of her father = 11 + 31 = 42 years
subtract(divide(add(subtract(subtract(69, 8), 8), 31), const_2), 31)
