Four numbers are in the ratio 1 : 2 : 3 : 5. Two times their sum is 44. Find the ratio in the numbers obtained by subtracting 3 from the cube of each number. |
2 : 31 : 204 : 999 3 : 13 : 208 : 992 11 : 67 : 219 : 1003 5 : 61 : 213 : 997 |
5 : 61 : 213 : 997 |
1 : 2 : 3 : 5 total = 11R So, 2 x 11R = 44 R = 2 Nos. = 2, 4, 6, 10 The ratio of their cubes = 8 : 64 : 216 : 1000 required ratio = 5 : 63 : 213 : 997 |
