Correct option is B

Given:

Akshay spends 40% of his income.

He saves ₹24,000.

Solution:
Saving % = 100% - 40% = 60%.
Income = $$\dfrac{24{,}000}{0.60} = 40{,}000$$​​

Alternate Method:
Spend : Save = 40 : 60 = 2 : 3.
3 parts = ₹24,000 

1 part = ₹8,000 

Income = (2+3)=5 parts = 5$$\times 8{,}000 = ₹40{,}000$$​​
