Option 4 : 44%

## Detailed Solution

Download Solution PDFA'sweight + B's Weight = 156 × 100/130

∴ A = 156 × 100/130 × 5/12 = 50 kg

∴ B = 156 × 100/130 × 7/12 = 70 kg

Initial weight = 50 + 70 = 120 kg

Now, after increasing B weight = 70 × 120/100 = 84 kg

∴ After increasing A weight = 156 – 84 = 72 kg

Required percent = (72 – 50)/50 × 100 = 44%
