<p><p>A, B and C entered into a partnership by investing in the ratio of 7:4:5. At the end of the year, the total profit is in the ratio of 21:4:10. Find the ratio of period of time they invested in the business.</p></p>
<p><p>Ratio of investment = 7:4:5</p> <p>The ratio of profit = 21:4:10</p> <p>Ratio of period = ratio of profit/ratio of investment</p> <p>=&gt; 21/7 : 4/4 : 10/5</p> <p>=&gt; 3 : 1 : 2</p></p>
(23 × 8) – (13 × 5) + 67 =? x 6
140% of 9/8 of ? = 108% of 2800
[564 + 32 of 18 × 9 ÷ 12 + 162 ] ÷ 4 = ?
The value of 97 × 103 is _________.
212.3 × 4414.7 × 4623.4 × 4845.85 = 462?
((67)32 × (67)-18/ ? = (67)⁸
33 × ?2 – 6 × 5 = 3270
{(? × 15) + (? × 45)} – 120 = 360
(3/7) x 868 + 25% of 240 = (? + 65)
