The price of sugar is increased by 20%. If the expenditure on sugar has to be kept the same as earlier, the ratio between the reduction in consumption and the original consumption is
-
- 1 : 3
- 1 : 4
- 1 : 6
- 1 : 5
Correct Option: C
| The raised price = | of the former price | 100 |
| ∴ The householder must now consume | of the original amount | 120 |
| ∴ The reduction in consumption = |  | 1 - |  | of the original consumption | 120 |
| = | of the original consumption | 6 |
Required ratio = 1 : 6
Second method to solve this question ,
| Required percentage = | | | × 100 | 100 + 20 |
| Required percentage = | × 100 | 120 |
| Required percentage = | % | 6 |
Required ratio = 1 : 6
