The ratio of the sa laries of Abbi and Monu is 6: 11. If their salaries are increased by 10 per cent and 12 per cent, respectively,
then what will be the new ratio of their salaries?

SSC MTS 26th July 2022 Shift-3
Explanation:
- The initial salary ratio of Abbi and Monu is 6:11.
- This can be taken as 6x for Abbi and 11x for Monu.
- Abbi's salary increase: 10% of 6x \[=>\] \(0.1 \times 6x = 0.6x\), making it \(6x + 0.6x = 6.6x\).
- Monu's salary increase: 12% of 11x \[=>\] \(0.12 \times 11x = 1.32x\), making it \(11x + 1.32x = 12.32x\).
- New salary ratio is \(6.6x: 12.32x\), simplifying to \(66: 123.2\).
- Simplify the ratio to approximately 3.3:6.16 or more accurately 33:61.6.
- Now, checking options:
- Option 1: 5:3 is far from the simplified ratio.
- Option 2: 15:28 roughly estimates to the required ratio.
- Option 3: 12:13 does not fit.
- Option 4: 17:23 also matches roughly close.
Thus, the right choice seems to be Option 2: 15:28
