</li><li><p>1.6% increase</p>
</li><li><p>1.4% increase</p>
</li><li><p>1.3% decrease</p>
</li></ol> <h2 id="content-id-0354291768-5"><b> Ratios And Proportion Questions Solution</b></h2><p>The correct answer is <strong>option 3</strong> i.e. <strong>1.4% increase</strong>.</p>

<p>Let the initial expenditures on rent, groceries and transport be 3x, 5x and 2x respectively.</p>

<p>Total initial expenditure = 3x + 5x + 2x = 10x</p>

<p>New expenditure on rent = 108% of 3x = 3.24x</p>

<p>New expenditure on groceries = 94% of 5x = 4.7x</p>

<p>New expenditure on transport = 110% of 2x = 2.2x</p>

<p>Total new expenditure = 3.24x + 4.7x + 2.2x = 10.14x</p>

<p>Required percentage = [(10.14x - 10x)/10] × 100</p>

<p>⇒ 100 × 0.14/10 = 1.4% increase</p>
