Mayank spend 35% of his monthly income on household items, 25% on electronic items, and 7% on medicines. He saves the remaining amount of ₹11,550. What is Mayank's monthly income (in ₹)?

₹35,000

Let total amount = 100

Spend on household items = 35% = 35

Spend on electronic items = 25% = 25

Spend on medicine = 7% = 7

Remaining = 100 - ( 35 + 25 + 7 ) = 33

33x = 11,550

then, 100x = \(\frac{11,550}{33}\) × 100 = ₹35,000
