Detailed Solution

Given, Bhavya’s income is ₹ 50,000 per month and spends 80% of her income. Due to pay revision, her monthly income rises by 20% but due to price rise, she has to spend 20% more.
Her expenditure before pay revision = 80% of 50000
               = 80100×50000
               = ₹ 40000
Her salary increased by 20%.
Her new salary = 50000 + 20% of 50000
= 50000 + 20100×50000 = ₹ 60000
Her expenses after the salary rise = 40000 + 20% of 40000.
= 40000 + 20100×40000 = 48000
Savings = income - expenditure
Savings = 60000 - 48000 = 12000
Hence her new savings are ₹ 12000.
So, option 1 is correct.
