My sister spends 45% of her monthly income on house rent, 15% of her monthly income on food and medicines and saves the remaining amount of Rs 6,270. What is her monthly income?

Rs 15,500
Rs 17,000
Rs 18,800

Rs 12,500

Validate

Solution:

Let my sister’s monthly income be Rs x.
∴ x = (45 + 15 + 7)% + 6,270
x = 67% of x + 6,270

x = 67/100x+ 6,270

x-67/100 x= 6,270

33x = 6,270 × 100

x={6,270×100}/33=19,000
