Given that,
original expenses $=$ $₹ 350$
Increased expense $=$ $₹ 500$
Ratio of original expenses to increased expenses $=$ $350 : 500$
Simplified form of $350 : 500$ can be obtained by dividing both terms by their HCF $50$
$350 : 500 = \frac{350}{500} = \frac{\frac{350}{50}}{\frac{500}{50}} = \frac{7}{10}$
Hence, the ratio of original expenses to increased expenses is $7 : 10$
