Given that,
Original expenses $=$ $₹ 350$
Increase in expense $=$ $₹ 500 - ₹ 350 = ₹ 150$
Ratio of increase in expenses to original expenses $=$ $150 : 350$
Simplified form of $150 : 350$ can be obtained by dividing both terms by their HCF $50$ .
$150 : 350 = \frac{150}{350} = \frac{\frac{150}{50}}{\frac{350}{50}} = \frac{3}{7}$
Hence, the ratio of increase in expenses to original expenses is $3 : 7$ .
