Three bags A, B and C contain apples. If 170 appies are moved from bag B to C, the ratio of the number of apples in bag A and bag C would be reversed. Instead, if 40 apples are moved from bag A to bag C then the number of apples in bag A and bag C will be equal. Find the number of apples in bag A and bag C together. |
Answer» number of apples in bag A and bag C together. = 1360Step-by-step explanation: Let SAY Apples in Bag A , B & C are respectively A , B & C If 170 apples are moved from bag B to C, the RATIO of the number of apples in bag A and bag C would be reversed. A /(C + 170) = C/A => A² = C² + 170C 40 apples are moved from bag A to bag C then the number of apples in bag A and bag C will be equal. => A - 40 = C + 40 => A = C + 80 Squaring both sides => A² = C² + 160C + 6400 C² + 170C = C² + 160C + 6400 => 10C = 6400 => C = 640 A = C + 80 = 720 A + C = 640 + 720 = 1360 number of apples in bag A and bag C together. = 1360 Learn more: There are 136 apples,170 MANGOES and 255 oranges .
