Sophia invests 25% of her monthly salary in insurance policies. She spends 15% of her monthly salary in shopping and 35% of her salary on household expenses. She saves the remaining amount of Rs. 9,050.What is Sophia’s annual income ?

Let Sophia’s monthly salary be Rs. x.

According to the question,

Sophia’s percentage monthly

expenditure = (25 + 15 + 35)%

= 75%

Savings per cent

= 100 – 75 = 25%

∴ 25% of x = 9050

$Rightarrow frac{25 imes x}{100}=9050 Rightarrow frac{x}{4}=9050$

$Rightarrow x=9050 imes 4=$ Rs. 36200

∴ Sophia’s annual income

= Rs. (12 × 36200) = Rs.
