A. B and C are boxes with marbles in the ratio 2 : 3 : 4. The total number of marbles in the boxes is 360. The above ratio can be
changed to 3 : 8 : 7 by which of the following?
(i) By transferring 20 marbles from A to B and 20 marbles from C 10 B.
(ii) By u.msferring 20 marbles from A to Band 10 marbles from C 10 B.
(iii) By transfen-ing 40 marbles from A to Band 20 marbles from C to B.
(iv) By transferring 30 marbles from A to B and 30 marbles from C to B.
(ii)
(iv)
(i)
(iii)
- Initially, the marbles in boxes A, B, and C are in the ratio 2:3:4. Calculate the number of marbles:
- Total marbles = 360.
- A = 2x, B = 3x, C = 4x. So, 2x + 3x + 4x = 360 ? 9x = 360 ? x = 40. Thus, A = 80, B = 120, C = 160.
- Check each option to see if the new ratio 3:8:7 is achieved:
- Option (i): Transfer 20 marbles from A to B and 20 marbles from C to B.
- New counts: A = 60, B = 160, C = 140.
- New ratio: 60:160:140 simplifies to 3:8:7.
- Option (ii): Transfer 20 marbles from A to B and 10 marbles from C to B.
- New counts: A = 60, B = 150, C = 150.
- New ratio does not simplify to 3:8:7.
- Option (iii): Transfer 40 marbles from A to B and 20 marbles from C to B.
- New counts: A = 40, B = 180, C = 140.
- Option (iv): Transfer 30 marbles from A to B and 30 marbles from C to B.
- New counts: A = 50, B = 180, C = 130.
- ?? Correct Answer: Option 3 (i)
