-
If the income of Company X in 1998–99 was equal to the expenditure of Company Y in 2001–2002, what was the ratio of their respective profits?
-
- 13 : 15
- 15 : 26
- 13 : 26
- Cannot be determined
- None of these
Correct Option: E
Suppose in the year 1998–99 expenditure of company X = रु a
Then profit earned by company X in this year = रु (30% of a) Hence, income of company X = रु (130% of a)
| = रु | 130 | x a |
| 100 |
Again, expenditure of company Y in 2001–02
| = रु | a + 130 |
| 100 |
Hence, profit earned by company Y in 2001–02
| = रु | a × 130 | × | 50 |
| 100 | 100 |
Thus, required ratio = profit earned by company X in this year : profit earned by company Y in 2001–02
| = | 30a/100 | = | 30 × 100 x 100 | = | 30 | = 6 : 13 |
| ( 50 x 130a )/10000 | 100 × 130 × 50 | 65 |
