Omkar's present age = (8x + 5) Nitin's present age = (7x + 5) Now, as per the equ. सहȣ वकãप: ड प च स ल पहल Đमश 8x और 7x कȧ उĨ मɅ ओमकर और ǓनǓतन कȧ उĨ दɅ ओमक र कȧ वत[म न उĨ = (8x + 5) ǓनǓतन कȧ वत[म न आय = (7x + 5) अब, EQUATION क अन स र Then, (8x + 5) + 3 = 12 (8x + 8) = 12 (7x + 5) + 3 11 (7x + 8) 11 On cross multiplication, we get 88x + 88 = 84x + 96
4x = 8 x = 2. Nitin's present age = (7x + 5) = (7 2 + 5) = 19 years. Hence, option D is correct. 6 Present age of A and B are in the ratio of 6 : 7 respectively. 8 years hence, the ratio of ages will become 7 : 8 respectively. What is A's present age in years? 6 A और B कȧ वत[म न आय Đमश: 6: 7 क अन प त मɅ ह 8 स ल इस लए, आय क अन प त Đमश: 7: 8 बन ज एग वषɟ मɅ A कȧ वत[म न उĨ Èय ह?
