Correct Option: E
As per the given bar graph ,
Income of company Q in 2001 = Rs. 40 crores
From question , we have
| Income of company Q in 2000 = | × 40 = Rs. | crores | 110 | 11 |
If expenditure in 2000 be Rs. y crores,
| Profit % = |  | Income – Expenditure |  | × 100 | |
| Expenditure |
| Profit % = | × 100 | y |
| ⇒ | = | = | 100 | 5 | 11y |
⇒ 5 × 400 – 55y = 11y
⇒ 66y = 2000
| ⇒ y = | = Rs. 30.30 crores | 66 |
Hence , expenditure in 2000 be Rs. 30.30 crores .
