Let the present age of Ashish be ‘x’ years. Present age of Vivek = 0.80 × x = ‘0.8x’ years Present age of Karan = 1.75 × 0.8x = ‘1.4x’ years According to question, 1.4x – x = 12 0.4x = 12 x = 30 So, the present ages of Ashish, Vivek and Karan are 30 years, 24 years and 42 years, respectively. Average age of Ashish, Vivek and Karan after 7 years = {(30 + 24 + 42)/3} + 7 = (32 + 7) = 39 years
