Question

Siva spends 78% of his monthly income. If he saves Rs. 7,700/- per month, what is his monthly income?

Answer 1

Let Siva’s monthly income = Rs. x 

Percentage of income spent = 78% 

Percentage of income saved = 100% – percentage of spent income 

= 100% – 78% = 22% 

Saved income = 22% of monthly income = 7700

= 22% of x = 7700 

⇒ \(\frac{1}{2}\) × x = 7700

⇒ x = \(\frac{7700\times100}{2}\)

⇒ x = Rs. 35000

∴ Siva’s monthly income = Rs. 35000
